- I am looking for bearings. I have all the loads on the shaft, so how do I calculate the stiffness and other bearing requirements?
Hi!
I am working on a design project. I already know all the loads (moment, force and gravity) on the shaft. I want to calculate the bearing requirements to help me choose the right bearing. All loads are very small, and the key requirement of the entire system is high accuracy.
Can I assume that all the loadings apply to bearing, then bearing need to be able to handle all the loadings and also maintain accuracy?
For example, if the total radial loading on the shaft is 10N and need accuracy of 0.01 mm for system. Can I say that the requirement of bearing stiffness is 10N/0.01mm = 1000N/mm?
