Roller Bearing Design and Installation Guide

The basic method to mount the OAV Roller Air Bearing is to transition fit both the OD and ID. If more than one bearing is used, a spacer may be inserted to secure the overall fit. Another means of installation is the injection method. Use an epoxy injection nozzle inserted in the housing epoxy port to inject after the bearing is installed in the housing for a permanent and secure installation.

It is crucial to avoid misaligning the bearings in the seats, and that the mounting loads are never applied through the side plate of the bearing. As shown below, the force should be applied to the face of the bearing itself (the middle component).

Typical Configurations And Design

Roller Air Bearings are light press-fitted into position on the shaft. A housing can be used to hold the roller air bearing. If a customer-designed housing is used, contact OAV for the bore size recommendation.


The roller bearing consists of the frictionless bearing and face collars all in one part. Therefore, the length of the bearing will be the length of the bearing system. The Roller Air Bearings have the same design guidelines as the Thrust Air Bushings.
