The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FKS-C1-H-1 (R166581323) is a high-precision ball runner block designed for linear motion applications where space is limited in the longitudinal direction. This model features a flanged, short, standard-height FKS format with an unalloyed steel CS body. It boasts a low preload class C and high accuracy class H, ensuring precise movement and alignment. The runner block comes equipped with a ball chain to facilitate smooth travel and minimize noise, as well as initial lubrication and preservation for extended service life. The B.RUNNER BLOCK CS has an overall length of . mm and can be used interchangeably with guide rails of every accuracy level. It is engineered to reduce frictional oscillations and maintain a low friction force level, especially under external loads. Attachments can be mounted from both above and below the runner block, which allows for maximum precision in various mounting configurations. With its patented entry zone, the runner block significantly enhances travel accuracy—up to six times—compared to traditional systems. Long-term lubrication capabilities are integrated into the design, potentially lasting several years without maintenance due to the presence of lube fittings with metal threads on all sides. This model is capable of handling high torque loads and offers exceptional rigidity in all load directions, enabling it to function effectively with just a single runner block per rail if necessary. It also supports equal high load ratings across all four main loading directions, contributing to maximum system rigidity when used in preloaded O-arrangement configurations. For applications requiring precise measurements, an optional integrated, inductive, wear-free measuring system is available. The B.RUNNER BLOCK CS excels in dynamic characteristics making it suitable for use on all SNSSNO Ball Guide Rails while providing excellent travel behavior thanks to its ball chain feature. In terms of environmental adaptability, the permissible ambient temperature range extends from min ... max °C for short periods; however, consultation is recommended for operation at negative temperatures. The product also offers various seal options like standard SS seals or special LS low-friction seals for different environmental conditions. Overall, this Bosch Rexroth linear guide component is designed for durability and performance in demanding applications that require precise linear motion control.
