The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 (R167221322) is a ball runner block designed for precision linear movement and guidance. This component is part of the linear guide technology and is characterized by its compact width, standard height, and normal length format (CNS). It is crafted from unalloyed steel CS, ensuring durability and strength for various applications. The runner block features a low preload class C and high accuracy class H, suitable for applications requiring precise motion control. Equipped with a ball chain, the B.RUNNER BLOCK CS facilitates smooth and quiet operation while minimizing variations in elastic deflection. It comes pre-lubricated with roller bearing grease Dynalub to ensure long-term lubrication over several years without frequent maintenance. The overall length of the runner block is specified as . mm, and it can be used interchangeably with guide rails of every accuracy level. Designed to handle high torsional moments on rails where lateral space is restricted, it offers high load ratings in all four main loading directions. The inclusion of two additional mounting screw holes at the center enhances rigidity under liftoff and side loading conditions. Its optimized entry-zone geometry allows for an increased number of balls, contributing to maximum system rigidity due to the preloaded O-arrangement. The product's dynamic characteristics are excellent, providing a high torque load capacity suitable for individual guide applications. It features integrated all-round sealing to protect against contaminants and an end-face fastening thread for easy attachment of accessories. The B.RUNNER BLOCK CS can be used on all BNS ball guide rails, offering versatility in its application. Additional specifications include a permissible ambient temperature range from min ... max °C (consult manufacturer for operation at negative temperatures), dynamic load capacity C determined as per DIN ISO standards, static and dynamic torsional moment load capacities Mt and ML respectively, friction coefficients within specified ranges depending on size profiled rail systems, standard seal SS for protection against environmental elements, internal product information regarding weight and nominal size compatibility with size H profiled rail systems.
