» Bearings for high speed operations - Evolution

Sep 15, 1994· With angular contact ball bearings running at high speeds the increase of stiffness will be greater due to the improved dynamic behaviour of the balls, i.e. the smaller change in contact angles. The smaller deformation in the contact zone of the ceramic rolling element and the steel ring also means that the contact area will be smaller.

Ball bearing - Wikipedia

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
