Air Bearing Bushings
Description:
Nelson Air's air bearing bushings can be used for both linear and rotary applications. The LB series of bearings utilize air bearing surfaces which provide excellent bearing stiffness and crash resistance. These bearings operate on standard precision ground shafting and deliver frictionless motion whether moving at low or high speeds.
In addition to the standard sizes listed below, custom bushings can be supplied with different lengths, housings and materials to meet your application's exact needs.
