The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 (R165182220) is a highly precise ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block is crafted from unalloyed steel CS and features a medium preload class C, which provides an average amount of pre-tensioning to the system for better performance and reduced clearance between components. It falls within the precision accuracy class P, ensuring a high level of travel accuracy. This model is characterized by its FNS format, which implies a standard width flange, normal length, and standard height configuration. It does not include a ball chain, but it does come with initial lubrication and preservation to ensure longevity and consistent performance right from the start. The runner block uses roller bearing grease Dynalub for smooth operation. The B.RUNNER BLOCK CS KWD-020-FNS-C2-P-1 has been designed without an attachment element on both left and right front reference edges, but it allows attachments to be mounted from both above and below due to its versatile design. For enhanced durability and performance under various conditions, it includes integrated all-around sealing. The product also boasts high torque load capacity across different preload classes. With additional mounting screw holes at the center of the block, this model offers improved rigidity under lift-off and side-loading conditions. Furthermore, it can achieve maximum system rigidity through a preloaded O-arrangement of balls within the runner block. An optional integrated inductive measuring system can be added for wear-free operation. This ball runner block is prelubricated at the factory for immediate use on all SN/SNO ball guide rails by Bosch Rexroth. Its design supports long-term lubrication over several years without needing frequent maintenance. The runner block can handle high load ratings in all four main loading directions due to its robust construction, making it suitable for applications that require just one runner block per rail while maintaining high system integrity.
