The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C2-P-1 (R165132222) is a ball runner block designed for high precision and rigidity in linear motion applications. This runner block is part of the Ball Rail Systems product line and features a size format FNS, with a width flange, normal length, and standard height. The body of the runner block is made from unalloyed steel CS, ensuring durability and strength. This model comes with an average preload class C for medium preload and an accuracy class P for precision applications. It includes a ball chain that contributes to low noise levels and optimal travel behavior. The B.RUNNER BLOCK CS is also equipped with initial lubrication and preservation, using Roller bearing grease Dynalub. The design incorporates straight lube connections that are loosely attached, allowing for easy maintenance. The runner block body comes in a standard version with no attachment elements on either front reference edge. The overall length of the runner block is specified in the product details. Notably, this ball runner block boasts interchangeability features, meaning it can be combined with guide rails of every accuracy level. It's engineered to meet high rigidity requirements, reduce frictional oscillations, and maintain low friction force levels even under external load conditions. The patented entry zone of this model increases travel accuracy significantly—up to six times—compared to other systems. Attachments can be mounted from both above and below the ball runner block for versatility in setup. Moreover, it supports high torque load capacity across various preload classes. With an optimized entry-zone geometry and numerous balls within its design, this product minimizes variations in elastic deflection while offering high rigidity in all load directions. This allows for applications that may require only one runner block per rail without sacrificing performance. In addition to these features, the B.RUNNER BLOCK CS provides improved rigidity under liftoff and side-loading conditions due to additional mounting screw holes at its center. For maximum system rigidity, it employs a preloaded O-arrangement. An optional integrated inductive measuring system can be added for wear-free operation if needed. Pre-lubricated at the factory for convenience, this ball runner block is compatible with all SN/SNO Ball Guide Rails by Bosch Rexroth and supports long-term lubrication over several years without the need for frequent maintenance. The B.RUNNER BLOCK CS offers impressive load ratings in all four main loading directions due to its robust design. It also includes integrated all-around sealing for protection against contaminants ensuring longevity even in challenging environments.
