Ball bearings - STC-Steyr

The contact angle is available as 25°, 30° and 40°. The greater the contact angle, the higher the axial load-carrying capacity of the angular contact ball bearings. The standard version of angular contact ball bearings is intended for bearing arrangements where only one bearing is used for each bearing point.

Four Point Bearings | Waviness Analysis

Four point bearings have on their outer and inner rings two circular arc-shaped raceways whose centres of curvature are offset so that during radial loading the balls contact the raceways at four points. The contact angles of four point bearings are large. Therefore these bearings are capable of transmitting high axial loads in both directions.

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.
