Force and Loading Analysis Four Point Contact Ball Bearings - …

Four point contact ball bearings are capable of resisting radial, thrust, and moment loads, it is ordinarily subjected to a coination of two or more of these loads wherever it is applied. If used exclusively, instead of two angular contact or two radial contact bearings, it will usually have all three types of loading applied.

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. In most
