The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-CNS-C1-H-1 (R167251320) is a high-precision ball runner block designed for linear motion applications where compact size, high load capacity, and precise movement are required. This runner block features a steel CS body with a size format CNS, offering a compact width, normal length, and standard height. It boasts a low preload class C and a high accuracy class H, ensuring smooth and accurate operation without the presence of a ball chain. The product is characterized by its ability to handle high torsional moments on rails with restricted lateral space while providing the same high load ratings in all four main loading directions. Long-term lubrication over several years is achievable due to the initial lubrication and preservation applied at the factory. The dynamic characteristics of this runner block are exceptional, with an excellent dynamic coefficient and high torque load capacity. Additional features include integrated all-around sealing for protection against contaminants, improved rigidity under lift-off and side loading conditions thanks to additional mounting screw holes at the center of the block, and compatibility with all BNS ball guide rails. The optimized entry-zone geometry and numerous balls reduce variation in elastic deflection, contributing to maximum system rigidity through preloaded O-arrangement. This ball runner block is suitable for use in environments with permissible ambient temperatures ranging from minimum to maximum degrees Celsius. It is also self-aligning to compensate for misalignments and comes without self-alignment as standard. The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-CNS-C1-H-1 (R167251320) offers an extensive range of accessories and end-face fastening threads for various attachments. It represents an ideal solution for applications demanding robust performance combined with precision linear guidance.
