Bosch Rexroth R201129334 Ball Runner Block

Bosch Rexroth R201129334 Ball Runner Block is a precision component that forms the moving element of Rexroth’s ball rail linear guidance systems. Designed to ride on a compatible Rexroth ball rail, it houses recirculating balls that translate loads into smooth, repeatable linear motion while helping maintain alignment under load. This model is part of Rexroth's B.RUNNER BLOCK family, a modular line engineered for high rigidity and long service life in precision automation applications. For proper installation and performance, pair this block with the matching Rexroth ball rail and the appropriate mounting hardware, and consult the official Rexroth catalog or product page to confirm size compatibility, load ratings, and installation requirements.
