Angular Contact Ball Bearings - an overview

In Fig. 4.6a is shown a single row radial thrust (angular contact) ball bearing. The contact angle a is the angle of the axis of contact between balls and races. For a single row radial ball bearing, the angle α is zero. If Fr is the radial force applied to the ball, then the normal force to be supported by the ball is.

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.

Ball Bearings: Guide to selection, appliions

XF r + YF a (3 for ball bearings and 10/3 for roller bearings) ( X = 1 and Y = 0 always). X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r.
