Question:

Selection of rolling bearings and sliding bearings 5

I recently learned some knowledge of rolling bearings and journal bearings. Questions to ask the experts:1, sliding bearings for high speed, heavy load, then in reality, how many high speed, large load sliding bearings?2, in addition to the speed and load, rolling bearings and sliding bearings at the choice of, there are other considerations? Such as price.3, rolling bearings can withstand the maximum speed is generally how much? Such as 7000RPM or 10000RPM.Relatively superficial problem, may not ask the key point, but also ask you to forgive me, thank you!

Answer:

The specific choice is usually to see the design needs. Plain bearings generally consider heavy loads or poor lubrication conditions.
For example, where oil lubrication or grease lubrication is not possible.Scrolling high speed depends on the selected bearings.
There is an article entitled "how to choose the correct size of the bearing". I wonder if it will help you
