- IN THIS VIDEO WE WILL DISCUSS ABOUT HOW WE CAN SELECT A PNEUMATIC LINEAR ACTUATOR/CYLINDER WITH THE HELP OF REQUIRED SYSTEM INPUTS. WE WILL ALSO LEARN HOW TO READ THE MANUALS OF STANDARD PARTS AND WHAT IS THE MEANING OF DIFFRENT TERMS INVOLVED INIT.
Very nice.mujhe jaisa chahiye tha waise completely practical shown fron catlouge.this step is very much imp in industry
Thank you.. Please do share the video🙏
nice... thanks bro
Thank you!!
HI. Do i need to take into account the pusher's mounting? If I got customize a pusher and mount on the rod
Hello Bennett...Yes you have to take into account the pusher's mounting on the pusher rod. You have to consider a floating joint also if there are misalignments. Also check the lateral load carrying capacity of the pusher. If your bore is too small and stroke is too long there might be chances of the rod bending.
Hi, may I know where’s the diameter 1 and 2 come from? Is the rod and piston is done selected so that we can choose the bore size? If I haven have any other size, but my object is only 4.5cm within 15gram, then I direct choose the smallest 12mm bore size, is it applicable?
Hello Roxanne...1) So D2 is actually the piston rod diameter which has been mentioned in the catalogue as D. The D1 is the piston diameter which is equal to cylinder bore diameter (Practically it will be some microns smaller than the bore diameter to have a sliding fit). 2) Your object is weighing only 15 grams which is equal to 0.015*9.8=0.15N approx. So even if you take the smallest possible bore in this series which is 12, it gives almost 42 N force. so, yes you can directly select 12 mm bore. my suggestion will be you can even go lower on the bore size. you can check other series of SMC or any other make like BIMBA, FESTO, CKD which can provide even smaller bores. (6- or 8-mm bore will also work for this). and one more thing to keep in mind is if you are going for this smaller bore, also check what stroke you require. because smaller bore cylinders have small piston rods so if longer strokes are selected there are chances of bending.
for most situation, μ should be 0.1
Yes. We can consider that on safer side.
Thank you..
you are welcome!!
Dear sir,
i want to be rail guide calculation & sliding unit on rail guide and move through cylinder how to cylinder selection
Hello Rohit...So I consider that you want to select a cylinder to move a load placed on a LM rail...Now in this case you have to calculate the equivalent load that the cylinder has to move. 1) Case-1 Load is moving horizontally...For that you can refer this link...tech.thk.com/en/products/pdf_download.php?file=511E_01_LMGuide.pdf. In this case as the LM rails have balls having very low coefficient of friction, you will require comparatively smaller cylinder. This is applicable if you are moving the load horizontally. 2) Case-2 Load is moving vertically... now if you are moving the load vertically, even though you use the LM rails they will act as a support, and you have to consider the total weight of the job directly for calculating the size of the cylinder. 3) from this you can calculate the size of the cylinder. Again, on the basis of the application you can then select the type of cylinder as simple, guided, rod lock etc.
@@IntroMech562 Thanks ....tray to upload any video with example
Could you please let me know when to use auto switch for the cylinder.?
Hello Sumit... So basically, auto switch also referred as reed switch is used to get the feedback of the piston position. So, the signal from auto switch is taken as the condition that the piston rod has reached at a specific location.
@@IntroMech562 ok , thanks for the information.
How to select among tie rod or round body or any other type of actuator
it's all depend on your application. if you have something that is needed to be guided properly then you can go with guided cylinders i.e. cylinders with guide/tie rod. But the cost of guided cylinder is almost twice than that of the normal cylinder. So you can also go with normal cylinder and separate guide rod and leaner guide bush assembly. The round cylinders you can use if you have small bore requirements or space constraints. But there are no such thumb rules. you can have n number of combinations of these different types of cylinders as per your application, budget , space availability etc.
@@IntroMech562 thanks
can you share the pdf of the video?
Hello Nicolas , this is the link: -content2.smcetech.com/pdf/CQ2_Z.pdf
I wanted to learn Pneumatic System Design, finally I can fulfil my lust for the same.
Thank you Irfan.. Do check out other videos also and don't forget to share!!
please the share the pdf
you can download the cylinder specification pdf from the SMC website. This is the link:-content2.smcetech.com/pdf/CQ2_Z.pdf
