Abstract

A multiple track linear motion recirculating roller bearing assembly is provided for movement on a substantially cylindrical shaft. The bearing assembly includes a housing with a pair of end caps having a plurality of radially arranged roller turnarounds therein positioned at either end. The housing defines a plurality of radially disposed axial roller tracks, each having both load-bearing paths and return paths, which paths are in communication with the roller turnarounds formed in the end caps. Axial roller guides are provided which extend longitudinally within the housing between the end caps and are uniquely formed as a single integral axial guide element. This integral axial guide element serves to receive and retain load-bearing plates therein. Rollers are disposed in both the load-bearing and return paths of the roller tracks and are adapted to efficiently move the carriage along a substantially cylindrical shaft.
