The Bosch Rexroth B.RUNNER BLOCK HS KWD-020-FLS-C2-H-1 (R200282390) is a high-speed ball runner block designed for linear motion applications that require precision and speed. This runner block is part of the Bosch Rexroth linear guide product range and offers features tailored for dynamic and accurate performance. The KWD-020-FLS-C2-H-1 model is constructed from carbon steel CS, ensuring durability and robustness in operation. The runner block boasts an FLS format, indicating a flanged design with a long body and standard height. It comes with a medium preload (Preload class C) for optimal rigidity and high accuracy (Accuracy class H), contributing to its reliable and precise movement. Notably, this model does not include a ball chain; however, it is equipped with initial lubrication and preservation to reduce maintenance needs. With an overall length of the runner block at . mm, it allows for interchangeability with guide rails across various accuracies, enhancing its versatility in different setups. This unit's design includes additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. The use of ceramic balls provides electrical insulation alongside reducing weight, which contributes to the runner block's high-speed capabilities. The B.RUNNER BLOCK HS is pre-lubricated at the factory with roller bearing grease Dynalub , facilitating long-term lubrication over several years while ensuring smooth operation. It’s designed to handle high torque loads effectively and offers equal load ratings in all four main directions of loading. The product also features an end-face fastening thread for attachments, lube fittings with metal threads on all sides for easy maintenance, and minimum quantity lubrication with integrated oil reservoirs. Its patented entry zone significantly increases travel accuracy up to six times compared to standard designs. Suitable for various sizes of profiled rail systems, this runner block can withstand maximum permissible ambient temperatures ranging from min ... max °C for short periods while maintaining its dynamic load capacity as per DIN ISO standards.
