The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FKS-C1-H-1 (R166581321) is a high-precision ball runner block designed for linear motion applications requiring compactness, precision, and durability. This runner block is part of the FKS series, which denotes a flange width, short length, and standard height configuration. It is constructed from unalloyed steel CS and features a low preload class C and a high accuracy class H, ensuring smooth movement and precise positioning without the inclusion of a ball chain. The runner block's overall length is tailored to suit applications with limited space in the longitudinal direction. It is engineered to provide significantly reduced frictional oscillations and maintain a low friction force level even under external loads. The design allows for attachments to be mounted from both above and below the runner block, offering flexibility in assembly. This model boasts maximum precision with its patented entry zone that can increase travel accuracy by up to six times. It is capable of long-term lubrication over several years due to its initial lubrication and preservation using Roller bearing grease Dynalub. The lube fittings feature metal threads on all sides for durability, while the end-face fastening thread accommodates various attachments. Equipped with an integrated all-around sealing system, it offers high torque load capacity across different preload classes. Its rigidity in all load directions allows for applications using just one runner block per rail without compromising performance. With high load ratings in all four main directions of loading, it provides maximum system rigidity when preloaded in an O-arrangement. The B.RUNNER BLOCK CS KWD-020-FKS-C1-H-1 can be used on all SN/SNO ball guide rails from Bosch Rexroth and supports optional integration of an inductive, wear-free measuring system for enhanced functionality. Its excellent dynamic characteristics make it suitable for various demanding linear motion tasks while ensuring reliability and longevity.
