Bosch Rexroth R162211420 Ball Rail Runner Block

Bosch Rexroth R162211420 Ball Rail Runner Block is a slimline, carbon steel carriage designed for precise, low-friction travel along a 15 mm-width ball rail. This runner block, identified by KWD-015-SNS-C1-N-1 and sold under the R162211420 designation, measures 58.2 mm in length and 34 mm in width to fit Rexroth’s 15 mm rail systems. Built as a ball rail runner block (CS), it provides smooth linear motion and robust support for automated positioning tasks in industrial environments. It’s used in a range of applications including machine tools, automated assembly, packaging lines, and robotics where repeatable carriage travel along a fixed rail is required. The compact footprint of the R162211420 enables it to be deployed in tight spaces while maintaining stability and alignment along the guide rail, contributing to accurate task execution and reliable uptime. As part of Bosch Rexroth’s ball rail systems, this runner block is compatible with standard 15 mm rails and is suitable for integration into existing Rexroth guideways or new builds that require a compact, rigid runner carriage for high-precision motion control.
