It is very knowledgeable video, and also your explaining langauge is very best because it is slowly and clear. Thanks.
As this is little complicated topic, so If you have any questions, or want more clarity on any part of this video please do ask. I would like to make a clarity video on your questions.
thank you
Thanks
You welcome 😊
hello, could you send a link to the skf pdf, where to find guidelines on preloading methods (construction), ring width, etc.? You used screen from it for example in 16;07
Sure Krystian, www.skf.com/binaries/pub12/Images/0901d196802809de-Rolling-bearings---17000_1-EN_tcm_12-121486.pdf
Maybe the wrong place but what about on mtb hubs with bearings.. would adjusting the play be preload ? If so how much space in between bearing and cone do you think would be needed for optimum use ? Mm?
I don't think MTB hub (Mountain Bike Hubs) comes with angular contact bearings. if it's simple ball bearing then preload is not required.
For motorized spindle for drilling application,spring preloading would be appropriate?and the general formula u used to calculate preload force can be used for NSK bearings? As the dynamic load rating of bearing we have selected is 23200N and if i take pf=1% then preload=232N so Medium preloading is selected
For machining applications I guess a fixed spacer preloaded would be better. And Yes, the same formula can be used for NSK as well
@mastermechanicaldesign for my application formula can be used?if not then what should i do ,we have gone through many papers but we couldn't get any preloading suitable for our application
Use universal matched pairs of angular contact bearings. As your application is a machining tool. You need precision. So selection preload class universal matched bearing. And there are three preload classes in SKF. But I'm sure about NSK. So try to find in their catalogue or on website
What type of bearing would be used in making a sand mixer (that used in foundries) and how should one approach a project like this.
Thank you
Type of bearings always depends on the load direction, the amount of load, speed, also what kind of misalignment is there, and we can decide the bearing size as per bearing service life calculation.
There is a complete process, I will make the detailed videos on bearing selection
Just after this bearing basic series
@@mastermechanicaldesign Thank you 🙏
@@mastermechanicaldesign Thank you 🙏
Sir,
In case of clamp or using lock nut,
How can I assume or put specific amount of preload?
For example, manufacturer need 100N +/- 10% preload on inner ring,
how can I apply that amount??
Please give me advice
I have seen in SKF, they use a Torque wrench. But i would highly recommend using a set of universal matched bearings. Instead of manual preloading
@@mastermechanicaldesign when I use torque wrench, what amount of torque Nm create 100N?
The bearings are not universal matched set.
This depends on many factors like as i said in this video.. I Can't surely say. Can't be manually calculated. Either consult with the bearing manufacturer sales team or use simulation software if the manufacturer is providing. That's the solution. It's risky.
That R temp formula is only for angular contact bearing or any type of bearing
This is for all types of bearings.
