Bearing structure

Angular Contact Bearing Cages

Plastic cages that guide rolling elements according to the bearing’s designed contact angle.

Product example. Geometry and supply are agreed for each project.

Application and design

The rolling-element type, contact angle and mounting arrangement define the cage geometry. The AXS series shown here is for axial angular contact roller bearings with cylindrical rollers.

Supply scope: Plastic cages only. Rollers, balls, bearing rings and complete bearings are not included.

AXS Series

Axial angular contact roller design

The cage pockets follow the designed contact angle in a thin-section axial angular contact cylindrical roller bearing. Contact angle and roller arrangement are confirmed from the drawing or approved sample.

Materials & customisation

Material selection considers pocket stability, molding of the angled geometry and the operating environment. A material grade is confirmed against the project requirements.

Choose from the nylon materials below for your cage design and operating conditions. The specific resin grade is agreed for the project.
