Coination Options for Angular Contact Bearing

To function properly, a precision angular contact bearings (ABEC 7 and up) needs to be preloaded against each other (or against an external force) to function properly. It’s only suggested for radial ‘deep groove’ ball bearings, not required. But a proper radial ball bearing preload will help you achieve a higher max RPM (if the radial

Angular Contact Ball Bearings from Koyo and JTEKT North

The preload can be built into the bearing or created when the bearing is Inserted into an assely. The contact angle varies from 15° to 40° and is measured relative to a line running perpendicular to the bearing axis. Angular contact bearings are unidirectional thrust bearings that can withstand heavy thrust loads and moderate radial loads.

Angular Contact Bearings Review - Engineers Edge

Angular contact bearings are asseled with a preload, which is applied between the inner race, the bearing ball and the outer race. The preload minimizes or removes gaps between the bearing balls and the inner and outer races. Angular contact bearings may operate with heavy thrust loads and moderate radial loads.

Bearing preload: What is it and why is it important

Spring loading is also a common method of applying preload to angular contact ball bearings in high-speed grinding spindles. The method is not suitable for bearing appliions where a high degree of stiffness is required, where the direction of axial load changes, or where undefined peak loads can occur.
