The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FKS-C1-H-1 (R166521321) is a high-precision ball runner block designed for linear motion applications requiring compactness, accuracy, and rigidity. This runner block features a size 25 flange width, short length, and standard height with a body made of unalloyed steel CS. It belongs to the preload class C, indicating a low preload for reduced frictional forces while maintaining high accuracy class H standards. Notably absent is the ball chain; however, it comes with initial lubrication and preservation. The Bosch Rexroth B.RUNNER BLOCK is engineered for applications where space is restricted in the longitudinal direction. Its design significantly reduces frictional oscillations and maintains a low friction force level even under external loads. The attachments on this runner block can be mounted from both above and below, ensuring flexibility in various mounting scenarios. Featuring maximum precision thanks to its patented entry zone that increases travel accuracy by up to six times, this runner block also supports long-term lubrication over several years, reducing maintenance frequency. It includes lube fittings with metal threads on all sides for easy access and an end-face fastening thread for all attachments. This product boasts an integrated all-around sealing system that enhances durability by protecting against contaminants. It can handle high torque loads and offers different preload classes to match specific application requirements. Its design allows for high rigidity in all load directions, which means it can be used with just one runner block per rail without compromising performance. Furthermore, the B.RUNNER BLOCK has high load ratings in all four main directions of loading and offers maximum system rigidity due to its preloaded O-arrangement. An optional integrated, inductive, wear-free measuring system can be included for precise motion tracking. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FKS-C1-H-1 (R166521321) is versatile and suitable for use on all SN/SNO ball guide rails. It provides excellent dynamic characteristics while being designed to endure challenging operating conditions with its robust sealing options and long-term lubrication capabilities.
