The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C3-U-1 (R16538392Z) is an advanced ball runner block designed for high precision and rigidity in linear motion applications. This runner block features a size 20 profile with a flange width, long length, and standard height, made from unalloyed steel CS for durability. It is characterized by a high preload class C and ultra precision accuracy class UP, ensuring maximum precision without the inclusion of a ball chain. The runner block boasts an overall length of . mm and is prelubricated with Roller bearing grease Dynalub for reduced maintenance. It does not come with attachment elements on either the left or right front reference edges but includes a straight lube connection loosely attached. The body of the runner block is in the standard version, allowing for interchangeability with guide rails of every accuracy. Designed to meet the most demanding rigidity requirements, this ball runner block significantly reduces frictional oscillations and maintains a low friction force level even under external loads. Its excellent dynamic characteristics are supported by a patented entry zone that increases travel accuracy by up to six times. Long-term lubrication over several years is facilitated by lube fittings with metal threads on all sides. The B.RUNNER BLOCK CS KWD-020-FLS-C3-U-1 offers high torque load capacity, various preload classes, and high rigidity in all load directions which allows for applications using just one runner block per rail. Enhanced rigidity under lift-off and side loading conditions is achieved through additional mounting screw holes at the center of the block. An optional integrated, inductive, wear-free measuring system can be included for precise motion tracking. Attachments can be mounted from both above and below on the ball runner block, which is compatible with all SN/SNO ball guide rails. The product ensures high load ratings in all four main loading directions and comes prelubricated from the factory to facilitate immediate use upon installation.
