Ball Bearing Preload - GMN Bearing USA

This constant contact is achieved through a bearing preload. Radial ball bearings don’t need nonstop contact between the balls and raceway; therefore, a preload is usually not required. However, sometimes a preload on a radial bearing is a better option than switching to a “preload required” angular contact bearing.

Analysis of Angular Contact Ball Bearings Design

2. Types of Angular Contact Ball Bearings The angular contact ball bearing is able to carry coined radial and axial loads or pure axial load. In this type of bearings the loads are transmitted from one raceway to another at a certain contact angle. The ISO has given the nomenclature of various dimensions of single and double row angular

Radial Ball Bearings Versus Angular Contact Ball Bearings

Angular Contact Ball Bearings Sometimes referred to as “spindle bearings,” angular contact bearings are used in machinery that requires high accuracy and durability. Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings.
