Plastic plain bearing Bosch Rexroth
Linear technology Bosch Rexroth
Bosch Rexroth plastic plain bearings are maintenance-free sliding elements for linear motion on precision steel shafts. They run without rolling elements and without relubrication and serve as an alternative to ball bushings where dry running, low weight or insensitivity to dirt is required. The range is organised by shaft diameter through consecutive R part numbers (R132050500, R132050600, R132051000 and more).
Typical applications: Plastic plain bearings suit simple linear guides with moderate loads, dusty or dirty environments, and applications where lubricants are unwanted. Selection follows the shaft diameter of the precision steel shaft in use and the required length; the matching R number ensures correct assignment.
