The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C0-H-1 (R165389320) is a high-precision ball runner block designed for linear motion applications requiring exacting rigidity and dynamic characteristics. This model features a size 20 steel CS runner block body with high accuracy (class H) and is preload-free (class C), ensuring smooth motion without pre-tension. The runner block does not include a ball chain but comes with initial lubrication and preservation, using Roller bearing grease Dynalub, to facilitate long-term operation without frequent maintenance. With a straight lube connection that is loosely attached, the B.RUNNER BLOCK CS offers straightforward maintenance. The overall length of the runner block is specified to accommodate various installation requirements. It boasts interchangeability with guide rails of every accuracy, making it versatile for different setups. Designed for demanding rigidity needs, this model has significantly reduced frictional oscillations and maintains a low friction force level, especially under external loads. The Bosch Rexroth ball runner block is notable for its excellent dynamic characteristics, including maximum precision enhanced by a patented entry zone that improves travel accuracy up to six times. It supports long-term lubrication over several years and features lube fittings with metal threads on all sides for ease of access. The end-face fastening thread allows for diverse attachments. This model is equipped with integrated all-around sealing to protect against contaminants and ensures high torque load capacity suitable for various applications. With different preload classes available and high rigidity in all load directions, it can be used with just one runner block per rail in some cases. The design includes additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. An optional integrated, inductive, wear-free measuring system can be added for precise feedback on positioning. Attachments on the ball runner block can be mounted from above or below, providing flexibility in design integration. It's compatible with all SN/SNO ball guide rails and delivers consistent high load ratings in all four main directions of loading. Pre-lubricated at the factory, this unit promises reliable performance right out of the box.
