The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C0-N-1 (R162129422) is a high-precision ball runner block designed for linear motion applications. It features a slimline width, normal length, and high height format (SNH), with the body of the runner block made from unalloyed steel CS. This model is preload-free with a preload class C and offers standard accuracy class N. It includes a ball chain to facilitate smooth movement and comes with initial lubrication and preservation, using roller bearing grease Dynalub. The B.RUNNER BLOCK CS KWD-025-SNH-C0-N-1 has an overall length of . mm and boasts interchangeability across guide rails with any accuracy level, enhancing its versatility for different applications. Its design allows for restricted space usage in the transverse direction while providing high rigidity, essential for applications demanding reduced frictional oscillations and low friction force levels, especially under external load conditions. With its patented entry zone, this ball runner block enhances travel accuracy by up to six times compared to conventional systems. It supports high torque loads and can be used in configurations that require only one runner block per rail due to its exceptional rigidity in all load directions. The product also offers long-term lubrication capabilities over several years, end-face fastening threads for attachments, quiet operation, various preload classes, outstanding dynamic characteristics, and compatibility with all SN/SNO ball guide rails. Key specifications include a permissible ambient temperature range from min ... max °C (admissible for short periods) and dynamic load capacities determined according to DIN ISO standards. The product's dynamic torsional moment load capacity Mt and static longitudinal moment load capacity ML are calculated based on standard travel distances. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C0-N-1 is a versatile, durable ball runner block suitable for high-precision linear motion applications requiring low noise levels and excellent travel behavior due to its design features like the ball chain return system.
