Ceramic Bearings vs Steel Bearings: An Engineering Analysis - Haini Engineering

11/12/2020· The only real big noticeable difference between the two is the bearing clearance. On ceramic bearings, this is usually a C3 clearance whilst on steel it’s usually CN. The bearing clearance is a measurement given to the small gap between the inner race, outer race and balls. It is required to prevent bearing seizure when it warms up and expands.

Technical Information: Ball bearing types, selection factors, and bearing …

Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.

30/10/2015· Because the contact area between the balls and races is so small, ball bearings can’t supoert as much load as other bearing types, so are best suited for light to moderate loads. However, their small surface contact also limits the heat generated by friction, which makes ball bearings useful in high-speed appliions.
