The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FLS-C1-S-1 (R165331120) is a high-precision ball runner block designed for linear motion applications requiring utmost accuracy and rigidity. This runner block is part of the Ball Rail Systems product group and is specifically crafted to meet super precision (SP) standards with a low preload class C, ensuring smooth motion with minimal friction and reduced oscillations even under external loads. The B.RUNNER BLOCK CS KWD-035-FLS-C1-S-1 features an unalloyed steel CS body without a ball chain, which allows for long-term lubrication over several years. It comes pre-lubricated from the factory with roller bearing grease Dynalub, enhancing its maintenance-free operation. The runner block's design includes an integrated all-around sealing to protect against contaminants, thereby extending its service life. This model boasts high torque load capacity and can be used in applications with just one runner block per rail due to its high rigidity in all load directions. It also has improved rigidity under lift-off and side loading conditions thanks to additional mounting screw holes located at the center of the block. The B.RUNNER BLOCK CS KWD-035-FLS-C1-S-1 is compatible with all SN/SNO ball guide rails and offers uniform load ratings across all four main loading directions. An optional feature for this runner block is an integrated, inductive, and wear-free measuring system that can enhance precision in applications where exact positioning is critical. Attachments can be mounted both from above and below the runner block, providing flexibility in system design. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FLS-C1-S-1 (R165331120) offers maximum precision, excellent dynamic characteristics, long-term lubrication capabilities, high load capacity, and compatibility with a wide range of rail systems—making it suitable for demanding linear motion applications where accuracy and reliability are paramount.
