The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C0-N-1 (R167159420) is a high-precision ball runner block designed for linear motion applications. This component is part of the Ball Rail Systems product group and is distinguished by its robust construction and advanced engineering. The runner block body is made from unalloyed steel CS, ensuring durability and strength. It features a preload class C, indicating that it is preload-free, and an accuracy class N for standard precision levels. This model does not include a ball chain but comes with initial lubrication and preservation to facilitate immediate use upon installation. The roller bearing grease Dynalub enhances its performance over time. The runner block's overall length measures precisely, allowing for compatibility with various guide rails within the same accuracy range. Designed to handle high torsional moments on rails, the B.RUNNER BLOCK CS KWD-020-BNS-C0-N-1 maintains high load ratings in all four main loading directions, making it versatile for different orientations of use. Its design also allows for long-term lubrication spanning several years, which contributes to reduced maintenance requirements. The unit boasts excellent dynamic characteristics due to its optimized entry-zone geometry and a substantial number of balls that reduce elastic deflection variations. It offers maximum system rigidity through a preloaded O-arrangement, enhancing its load capacity and resistance to torsion—making it ideal as an individual guide in demanding applications. Notably, this ball runner block can be used with all BNS ball guide rails and has a wide range of compatible accessories. It includes end-face fastening threads for attachments and lube connections with metal threads on all sides. Additionally, two extra mounting screw holes at the center increase rigidity under liftoff and side loading conditions. The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C0-N-1 (R167159420) stands out for its ability to accommodate misalignments without self-alignment features while maintaining low friction coefficients. Its seals are designed to keep contaminants out effectively while providing low friction operation which extends the service life of the component.
