The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-P-1 (R165121220) is a state-of-the-art ball runner block designed for high rigidity applications and characterized by its precision and low preload. This runner block is part of the Ball Rail Systems product line, crafted from unalloyed steel CS and designed to meet the highest standards in terms of size, format, and accuracy. It boasts a preload class C indicating a low preload level and an accuracy class P for precision. The B.RUNNER BLOCK CS is notable for its excellent dynamic characteristics, significantly reduced frictional oscillations, and low friction force levels, especially under external load conditions. Its patented entry zone increases travel accuracy by up to six times. The product provides options for mounting attachments both above and below the runner block body, which comes in a standard version with an overall length specified in the detailed product features. This ball runner block is equipped with all-around sealing and high torque load capacity. It offers different preload classes to cater to various application needs and ensures high rigidity in all load directions. This allows for applications that may require only one runner block per rail. The design includes two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. For enhanced system rigidity, it features a pre-tensioned O-arrangement and has the option of an integrated, inductive, wear-free measuring system. The B.RUNNER BLOCK CS comes pre-lubricated from the factory for long-term lubrication over several years. It can be used on all SN/SNO ball guide rails and supports high load ratings in all four main loading directions. Additionally, this runner block accommodates various environmental conditions with permissible ambient temperatures ranging from minimum to maximum degrees Celsius as specified in its detailed specifications. It maintains compatibility with E profiled rail systems among others, ensuring interchangeability between the runner block and guide rails across every accuracy level.
