The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C2-U-1 (R16513292Z) is a ball runner block designed for high rigidity and precision applications. It features a size FNS format with standard width, length, and height dimensions. The runner block body is crafted from unalloyed steel CS and is characterized by a medium preload class C and an ultra precision accuracy class UP. Notably, this model does not include a ball chain but comes with initial lubrication and preservation. The product is equipped with roller bearing grease Dynalub and has lube connections that are straight and loosely attached. The overall length of the runner block is specified, ensuring interchangeability with guide rails of every accuracy level. This runner block excels in dynamic characteristics, offering reduced frictional oscillations and low friction levels, particularly under external loads. With its patented entry zone, the travel accuracy is significantly enhanced—up to six times—making it ideal for applications requiring maximum precision. The design allows attachments to be mounted from both above and below the block, while end-face fastening threads accommodate all attachments efficiently. It also boasts integrated all-around sealing for protection against contaminants. The B.RUNNER BLOCK CS KWD-035-FNS-C2-U-1 can handle high torque loads and offers different preload classes to suit various application needs. It provides high rigidity in all load directions, which permits the use of just one runner block per rail in certain scenarios. Additionally, it features improved rigidity under lift-off and side-loading conditions due to extra mounting screw holes at the center. This model can be used on all SNS/SNO ball guide rails and offers long-term lubrication capabilities extending over several years without maintenance. It maintains high load ratings in all four main loading directions thanks to its robust design. Optional features include an integrated, inductive, wear-free measuring system for enhanced functionality.
