Thanks for the video. You both explained all the questions I had with perfect detail; opening the unit itself and displaying the inner working of the actuator was a bonus.!
The damn Actuonix linear actuators with potentiometer feedback don't even come with limit switches. I hit the limit for a just a second and the entire housing started warping. Damnedest thing I have ever seen. Glad you guys designed it right.
Great video guys, I will be using this information for sure! Will send you guys an email shortly regarding a project.
Thanks again for the upload.
This was an amazing video, thank you very much. Really liked that you taken it apart too.
+Colin Richardson Thanks, Colin!
Exactly what I was looking for, Thank you very much. :)
really appreciate this video now I know what I need
A great explanation. I now know 100% more than I did 12 minutes ago!
Glad you found it helpful! Let us know if you have any questions tech@servocity.com.
Great video with simple language for a complex system. I'm a absolute novice but learning so much from these videos, thank you
We're glad you find our videos helpful! As always, don't hesitate to contact us should you have any questions tech@servocity.com.
Very well edited and great info!
Thanks, Michael! Glad you enjoyed it!
Thanks Tom and Dustin. Great job.
This WAS a really good instructional video. Excellent.
Thanks, Dennis! Glad you found it helpful and informative.
Great video, area there any problems that you are aware of regarding installing them in a hot humid greenhouse for ridge and side vent opening? Thank you.
Thank you so much for the video..its very informative..
I had coded a program to set a timer to count the forward extension and reverse retraction of the actuator using 16f877a and to display the time in LCD.
Roopa B please help. How to read position of the actuator with reed magnetic sensor in arduino?
To be more precise, DPDT = Double POLE Double Throw switch. Good intro to servos & actuators!
Great video guys. Minor correction: You meant "double pole double throw" switch. Cheers
Thanks Man, it was awesome video, I will be contacting you guys later on for assistance on my project.
This video was fantastic!
Thanks, Tom. Glad you found it helpful.
excellent video!!! Thanks for posting....it really helped me out for the project I was working on.
You're most welcome. Glad it was helpful for your project!
great video. it helped me. thanks
Glad you found it helpful!
I would like to trigger a light to come on when the actuator is fully extended. Is this possible?
Hi David, there are various ways you could go about it. For example you could use a limit switch ( www.servocity.com/electronics/components/switches/limit-switches ) that is physically engaged to turn on the light. Or you if you are using something like an Arduino or Raspberry Pi with a servo hat you could use a linear servo ( www.servocity.com/servos/linear-servos ) and a PWM switch ( www.servocity.com/electronics/components/switches/pwm-switches ) and send two PWM signals, one to control the linear servo and one to turn on the light via the PWM switch. You could also use a PWM switch with a Y-harness and linear servo to run them both off of the same PWM signal (like from an RC receiver or Arduino, Raspbery Pi etc) but the light would turn on the entire time the servo is extending and not just at full extension. Let us know if you have any other questions tech@servocity.com.
thanks you guys are awesome.
David Guyton i
@@sharpfinch5354 And it will be thew best thing for her.
David Guyton Yes its possible
great video guys !
+Makayla Felipe Thank you, Makayla!
Great video. My question is, can I remove the cover of my "Windy City" actuator and reposition either, or both of the limit switches to stop the extension, or retraction, at a particular position? Thank you.
this is what i looking for.. thanks for the video..
Glad you found it helpful!
Thanks u very much 🙏 thats the information what am looking for excellent n informative 👍👍👍best
Bravo and thank you very much for this video
Very well explained !
Hi, thanks a lot for your interesting video;
I just have a question if you permet
Does the linear actuator contain a limit switch that stop it even if we're giving an order to the motor to move ( forward and backward) ?
THANKS :)
Looking at one of these linear servos to convert a riding mower into a RC mower. Gonna need one for steering, and a light duty one for actuating the hydrostatic transmission control lever. It's gonna be sweet!
I am looking for some ideas as to how to build an old school arcade driving cabinet like Out Run where with the turn of the wheel, the base would move. I am thinking about putting an actuator or servo, I think 4 will do the job. But what I don't know is where to start or look for. Would something like these work at high speed sensitivity and would they handle the weight? I originally was looking at hydraulics, but outside of weight, they would seem slow. Suggestions?
Thank you for reaching out to us. If you could please send additional specifications to our technical department they would be happy to help with some recommendations at tech@servocity.com
Nice, educational video. Thanks.
Glad you found it helpful!
For my application I need 2, of the 2" Stroke 115 lb Thrust Heavy Duty Linear Actuator, I wanted to know if I could use a, "Thrustmaster USB Joystick (PC)", or which one do you recommend. I don't understand much. I have seen your video.
Thanks Raffaele
Hey guys just stumbled upon your channel after trying to find a solution to a problem im having. I have little knowledge of anything to do with servos and could really use a hand figuring out what i need to do what i need to do. Im trying to make an exoskeletal arm brace/ elbow joint for my mum who suffered from arthritis and had many failed attempts at replacing the joint. She now has no elbow or bone 8 inches either side of where the elbow should be. Ive figured out the rigging now im stuck on how to wire up an actuator to extend and hold in place with one button and retract and hold in place when released with another. This is a long shot and im sure youre very busy but any push in the right direction would be amazing! Thanks for your time. Karl :)
Hi, Could you tell me what model linear servo you use in the video. What was the speed of it? Thank you.
Very Nice Description. Can a Micro:bit or Raspberry PI be used to control the Linear Actuator? Thanks!
Great info! Thanks!
Thanks, Phil. We're glad you found it helpful.
A couple questions! What is the noise rating on the servo? Also, if I were to open the servo and move the limit switch on the fully-extended side (desolder, drill, solder), would the servo have a correctly-functioning shortened range? I'm looking to do ~85 lbs with a ~1.5" throw and it would be excellent to have the safety in hardware, not software.
Nice video. Very helpful indeed.
I have been going through some linear actuator sites, they mention usage rate or duty cycle like 20% in their specifications, what does this mean?? Could anyone explain.
I am looking for a linear actuator , 80MM/sec speed, with Hall effect encoder for position feedback. The actuator would be active every 2 minutes, with rest periods of 2-5 minutes. Will this type of operation affect the life of the motor ??
GREAT VIDEO!
I want to put an actuator on my lawnmower deck. How do I calculate the size, travel, and strength needed? The mower deck is roughly 200 lbs.
Thanks!
I bought an actuator for my boat trim motor and it lasted about 3 weeks before it died. I made sure it was water proof and then I also sprayed it with water proofing. So that is one thing you forget to mention. It had much more dynamic and static load rating than I needed and was the correct voltage. It was slow but I would rather slow than not enough lift. Anyway, I would be interested to know what went wrong. The company had a 30 day return but by the time I was able to install I really only got about 3 weeks out of it and maybe had to lift the motor 8 times during that period. Can you comment on what may have/could have gone wrong ?
Very good demo.I like the contrast between you two, I actually learned a lot from two perspectives, that was very thorough and satisfying considering my obsession with finding out everything tech,especially electric motors I will subscribe and like. I love the way you get down to business, no extra B.S. I’m a K.I.S.S. fan myself, keep it simple is usually my aspect on things, I also enjoyed the disassembly, appreciate the convinces you 2 have provided and fantastic presentation!
Thanks, Tommy! We appreciate the kind words and are glad you found it helpful!
You guys are great together, Cracked me when you pulled out the linear servo how Jason was looking at you thinking "why is this dude trying to one up me man"
Do you have an idea of the weight lifting capacity of these items?
Hey, what would I need in order to be able to control force, so let's say it's some kind of actuator that can pull max force of 100lbs but if I set it half way then I can still pull the full range of actuator range but it would be 50 lbs, quarter setting 25lbs, ect.??? So like a shock absorber but with on the fly resistance control?
in case of a real closed loop control, ism't it more correct to use the last stage sensor in place of in-box potentiometer?
Great video
Hi, I have question, I have got the Linear 12 V -DC, 300N, 50mm stroke length the same as Jason tested. I connect to Adaptor 500 mA, but does not work is it because I need more Ampere for 12 v dc adaptor?
Thanks for showing that actuator. I thought I would need a hydraulic cartridge to push something up, but that should work.
Glad you found it helpful, Ted. Let us know should you have any questions tech@servocity.com.
I have a few questions about the linear servo.
I would like to do position control what would I need for this? Just a PWM Signal?
Also this has a Yellow, Black and Red wire which is which?
Yes, a PWM signal will tell the linear servo exactly what position it needs to be at (just like a normal servo). On a servo lead the Red wire is + the black wire is - and the yellow wire is signal.
Great vid. Do you know would you go about controlling the specific position of the actuator throughout the day? Like for a solar tracker. Cheers!
It sounds like you're after a linear servo of some sort, likely combined with a microcontroller to send it position commands such as an Ardunio (www.servocity.com/pololu-a-star-32u4-prime-sv/)
To interpret the signals from a solar tracking sensor or something of the like.
In terms of controlling the analog potentiometer, do you have any equipment on your website or alternate suggestions which connects to a PC, allowing one to set the actuator position by computer?
Thanks guys!
At this time we do not sell any products which allow you to read an analog signal (such as from a potentiometer) from an PC. That being said you might take a look at microcomputers as a means of doing this depending on your project requirements. Please let us know if you have any additional questions tech@servocity.com
Dear Servo City, that is very helpful video, many thanks!!
I have one question though, is the any way to vary the output force of the actuator?
The output force can be varied by changing the voltage or limiting the current supplied to the motor. If you want to have even more control there are force sensors available that could be used in conjunction with a motor controller as a closed loop system. Please let us know if you have any other questions tech@servocity.com
hi, I have one of those activators (4 inches) is what I can lift my tractor snowblower that weighs 300lbs, thank you.
😃 Espectacular muy bien 😃👍👍.
super video...ı was wondering the sytstem and thnxx really
Is it possible to have it extend and retract on a constant basis?
can this be use to move the handles in a hydraulic crane system?
I am looking for a mechanical device that creates more force in one direction than the return stroke. to shake gold particles along a shaker table. if the force is equal = no movement gained. any ideas.
Hello! Great video. Is it possible to create an automatic reciprocating (preferably adjustable) movement with a linear actuator (without having to turn a switch back and forth) and if so what equipment would one need? Thank you so much 😊
arduino
Do they make LAs that aren't DC? I'm concerned about brushes and that kind of wear. Do they make brushless LAs?
kewl video guys!
Thanks, Joe!
hello, excellent video !!! Do you know if the linear servos or the linear actuators would have the necessary force to be able to step on the clutch of a mechanical car?
If so, please recommend one.
I am disabled, I appreciate your response.
Glad you found our video helpful, Braulio. Yes, a linear actuator or linear servo is capable of actuating the clutch on a vehicle. There are a lot of variables involved such as the position of the actuator in relation to the fulcrum, the type of clutch (mechanical, hydraulic, etc.), the pressure of the clutch, rated force of the actuator, etc. Please contact us should you have any additional questions tech@servocity.com, we'd be glad to help.
I am ready to buy the linear servo for an autonomous boat installation using the PIXHAWK
Flight/ navagation controller
A- How do I go about connecting the pixhawk to the linear servo?
Thanks for a great instructional video. I am going to use actuators to control my boats speed and shift her transmission. Do you know of any better suited for the marine environment?
While there are marine grade linear actuators on the market, we do not offer them or have a suggested source that we know to send you to unfortunately. Feel free to reach out to our Tech Team should you have any other questions tech@servocity.com.
o yes, i thought it doesnt have feedback from the actuator. i need this on my thesis. thanks for the video.
Thankyou very much
Sir which are leading company of linear actuators like linak denmark
Do you have any model that uses stepper motor instead?
I loved the way the linear actuator moved. Way better than the servo's jerky moves.
sir ,how much maximum weight lifts the actuator
Great review. I have a question. If you stop it in the middle before it hit the limit switch and keep for a few hours does it use any electricity and drain the battery?
The current draw will be considerably less given the motor is going to be at idle but it will continue to draw from your battery until it's turned off of the battery is discharged. Let us know if you have any other questions tech@servocity.com.
thanks man! i just have a question, what do you call the gear that moves the threaded rod up and down?
The threaded rod (lead screw) gets rotated, it has a lead screw nut which moves up and down along the lead screw as the lead screw rotates.
First it's not up and down. It's in / out or extend / retract.
Next the screw rotates, it doesn't move in or out. The lead screw nut is what travels along the lead screw and Push Rod / Extension Tube is attached to that nut.
The gears that drive the lead screw are a combination of a worm drive/screw that drives the rest of the spur gears.
OOPs My apologies. The one he is showing here does not use a worm gear. It is just a set of spur gears.
Can you provide links to the Proportiojnal Actuator and Controller
I have a question. Can I use the linear actuator to do the automation of the window in smart buildings?
Can i control it using my daq and labview ?
In my case, the windows must open depending on the temperature of the space.
Hi Julien, if the stroke and thrust of the linear actuator is adequate for the task then it should be a fine option. From a control standpoint, an actuator could be wired to a motor controller and it would be up to the controller that you choose to sense things like temperature. Feel free to email our Tech Team should you have any other questions tech@servocity.com.
great video, what can i buy to open and close a ball valve 4" any suggestion?
It depends on the torque required to rotate the valve but a conventional servo would be a good candidate for this application. Feel free to email our Tech Team with specifics and they'd be glad to help answer any additional questions tech@servocity.com.
Where I can buy
Kyle/Jason, What could be the maximum speed that these rods can extend at?? I need something that can push or pull really really very fast. Is that possible??? Saba.
Hi Saba, the pitch and RPM will determine max linear speed. Lead-screws are not normally chosen for high-speed. Pneumatics might be a better option for you. Let us know if you have any other questions tech@servocity.com.
Hi guys! I have been enjoying the channel! Thanks for all the useful info! I have a question about linear actuators and remote setups that - I don't know if you could answer for me? But I thought you might at least be able to point me in the right direction... I have a project I'm working on that requires 2 sets of actuators. I would like them to operate independently and I am trying to use 1 power supply and 1 2-4 channel remote. Let me know if you can help. Take care!
Thanks, Ryan and glad you've found our videos helpful! Our Tech Team has sent an email your way to answer your questions. Let us know if there is anything else we can assist with.
If your still around I would like to ask a question. I have an actuator that has stopped working (extending and retracting) and need to raise (retract) the shaft to its shortest length. What would be the simplest way to do this manually, if possible?
It depends on the design of your actuator, but if you can access the lead screw driving the piston, just rotate the lead screw manually (assuming it will still turn) to manually extend/retract. Feel free to contact us should you have any other questions tech@servocity.com.
Awaome video and display .. 👍👍
Thank you!
Hi, I'm thinking of using the Linear Servo (similar to the one Jason used in this video) to drive my syringe pump. I am quite clueless on this and trying to find the right controller and battery. Which controller was used in this video? And what was the ampere hour draw of the battery used in the setup on the video (I would like to know what level of the ampH battery to buy)?
Thanks
Hi Angelique, we're happy to help answer your questions. The linear servos will run on any type of servo controller able to operate a hobby servo. The Actobotics Dual Servo Controller (www.servocity.com/actoboticsr-servo-controller-w-enclosure) was used to operate the linear servo in the video (reference 6:30). The battery was just a lawn mower battery so that the power source would be quickly recognizable by viewers. Any 12V source will be fine so long as it can provide enough current to operate your linear servo (more applicable when selecting the proper power supply that plugs into the wall). The capacity of the battery will depend on the desired run-time and the current draw from the linear servo will depend on the load and frequency of movement. If you have any other questions feel free to let us know! tech@servocity.com or 620.221.0123
ServoCity Thank you so much
Are there also linear actuators that you can also move by hand and get positional feedback?
Linear Actuators and Servos would be nearly impossible to move by hand with their 500lbs. static load. Let us know if you have any additional questions tech@servocity.com.
yesssss! they considered visual learners! gonna figure out how to pop these into a computer desk 😈
Forwarning, they aren't very powerful unless you pay a bit. Lifting an empty deal sure. But with a monitor and a few books it may struggle.
i, I have an INCA TV lift with a tubular motor. We lost the remote, and
lift got stuck in up position. Any advice how to bring it down? Any
ideas or how to reverse the motor movement? Highly appreciated. Thanks
for sharing awesome ideas.
Hello!
That sounds much outside the realm of our technical support. If you'd like you can send our team an email and see if they can help you out. But no guarantees they will be able to assist troubleshooting other company's products.

Awesome vid...does the amp of battery effect the actuator? Asking because I plan to install 2 linear actuators in my truck and debating if I should tap off the truck battery or off separate battery. Thanks
Thanks, Benjamin. If you are running linear actuators, you can tie them into your vehicle battery without a problem. The motor in an actuator won't be bothered by the fluctuation in voltage due to the alternator. More care would need to be taken if a micro-controller were in the equation. Feel free to email us should you have any other questions tech@servocity.com.
@@ServoCity awesome, thank you!!!
How do you call an actuator that has a linear motion , but also has the rotating motion (screw or turning head)
How do I find out if these work with 220v or 110v? I bought a Linak linear actuator but it doesn't specify.
Our actuators are 12V DC powered. A 110v to 12v converter like a Hitec 12V - 18V, 30A Power Supply would work well www.servocity.com/12v-18v-30a-power-supply. Please let us know should you have any additional questions tech@servocity.com.
any silent actuators ??
Hi any brand you would suggest for underwater linear actuators? I need them underwater on the beach (salt water) for many month, powered from a 12V battery + solar panel on a pier (I have permit don't worry). thanks
Sorry but we do not have a suggestion for a marine grade actuator.
You didn't open up the linear actuator.. I wanted to open up mine to change the position of the limit switch.. Would you recommend to do so?
Here's a video on how to adjust limits on the Super Duty linear actuators. ua-cam.com/video/3jzyQ5gQUFE/v-deo.html Heavy Duty linear actuators do not have adjustable limits. Please let us know should you have any other questions tech@servocity.com.
Is there a servo or actuator that is big enough to reach 8-10 feet? Or something that can reach close to that height? Working on a project for wireless surveys and need something like this to add to a pi
There are some very large linear actuators on the market, but I doubt you'll want to tote something of that scale around given the weight that is likely to be associated. If you take on building something for your application you might get some inspiration from an extension ladder; pull the rope and it extends out. You could use a motor to reel in the rope or cable that you use to drive your assembly. Feel free to email our Tech Team should you have any other questions tech@servocity.com.
Hi there,
I've just bought one from ebay very similar to the one in your video. Its 12v but much slower than I've seen in your video or any video. Is there something wrong with it?.
Help appreciated
Andy
That's hard to say given it's not our product. It could be faulty or could just be a different ratio than what you're comparing it to. Please feel free to reach out to our technical team at Tech@ServoCity.com if you have any additional questions. Thank you.
What a racket those things make!!
Does every linear electric actuator comes with these 4 wires, two for power supply and the other two for control?
Linear servos have five wires total. The large red and black, terminated with a tamiya connector are for 12VDC power. The black, red and yellow with a TJC8 servo connector are to go to your servo controller. Linear actuators have five wires too. The red and the black go to the motor, the blue, yellow and white go to the potentiometer. Please feel free to email our Tech Team should you have any additional questions and we'd be glad to help! tech@servocity.com.
What do you recommend for higher speed motion, >>2"/s and less than 50 lb load?
Pneumatics are a good higher speed option for linear motion. Please feel free to reach out to us, if you have any further questions at Tech@ServoCity.com.
I have a 2" actuator but only need about 1 1/2 of stroke. I want to run a non momentary switch but can I readjust the limit switch to stop on the out-stroke at 1 1/2? If so, how?
Unfortunately, the limit switches are non-adjustable. Adding external limit switches would be the best solution for a shorter amount linear travel. Please let us know if you have any additional questions tech@servocity.com.
Awesome work guys...I have some queries about the servo actuator...how can I contact you?
Hi Sammy, you can email tech@servocity.com with your questions and our team would be happy to assist.
thinking of building my own screen for my home theatre projectore. i want to build a simple frame that would mve black board top and bottom from 16/9 rastio to the ratio 2.39:1. Esentially i am thinking 2 pieces of wood or light material that will move together so when i press a button botom frame goes up and top part of frame goes down. I can build frame easy enough but if i can find some cheap lightweight servoc one for top frame and one for bottom then i think it would work, but not wanting to spend alot, cheap is cheap. Any recomandations for none industry standared parts, for the home brew kits
If you have to move each panel in two directions you might want to look into building a frame behind the panels (think XY table) and fasten the panels to the movable dolly. You'll then want to select a drive mechanism that works for you (timing belts and pulleys, lead-screws, cable and pulleys, friction drive, etc.) Feel free to reach out should you have any other questions tech@servocity.com.
Hi. I was considering to use a linear actuator to change the tilt angle of a structure holding solar panels. Overall, around 200kg. Would this option vaild to keep the structure to a certain angle for longer periods? Or the weight would push it back? Thanks
Hello thank you for reaching out to us. Please email our technical team at Tech@ServoCity.com with your project details and they would be more than happy to help you.
Hey @MrSavage77 did you find any linear actuator that worked for that kind of load?? I'm looking for something similar for a project.
how can rise weight in kg
and we can use in kitchen cabbinets
i would like to use one of these to lift and lower my JD 44 inch snowblower on my x 300 Lawn tractor,will the cold affect the function? slow or stop it from working?
The cold should have no affect short of edge cases like if water somehow got inside in which case freezing temperatures would expand it as it turns to ice which may cause damage. Given their IP ratings this is unlikely. You can check the IP rating of the one you are interested in and look up the meaning with this chart www.servocity.com/glossary/#ingress-protection
