The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 (R165181323) is a high-precision ball runner block designed for use in linear motion applications requiring rigidity and accuracy. This product features a size FNS format, with a flange width, normal length, and standard height. The runner block body is constructed from unalloyed steel CS and offers low preload in preload class C and high accuracy in class H. It comes equipped with a ball chain, initial lubrication, preservation, and Dynalub roller bearing grease. The B.RUNNER BLOCK CS is devoid of attachment elements on both the left front reference edge and the right front reference edge but includes a straight lube connection that is loosely attached. The overall length of the runner block is specified in the product details. This component boasts interchangeability with guide rails across all accuracy levels, making it versatile for different setups. Key capabilities include reduced frictional oscillations under load, maximum precision due to an innovative entry zone that enhances travel accuracy by up to six times, and the ability to mount attachments from both above and below. It also features integrated all-around sealing for protection against contaminants and a high torque load capacity. The optimized entry zone geometry coupled with a high number of balls minimizes variation in elastic deflection while maintaining high rigidity in all load directions. This allows for applications using just one runner block per rail if needed. Enhanced rigidity under lift-off and side-loading conditions is achieved through additional mounting screw holes at the center of the runner block. For systems requiring maximum rigidity, this ball runner block can be preloaded in an O-arrangement configuration. An optional integrated measuring system can also be added for precise motion tracking without wear concerns. Pre-lubricated at the factory, this Bosch Rexroth ball runner block is compatible with all SN/SNO ball guide rails, supports high load ratings in four main loading directions, and allows for long-term lubrication over several years.
