The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-BNS-C0-H-1 (R167159372) is a high-precision, corrosion-resistant ball runner block designed for linear motion systems. This product is part of the Ball Rail Systems and is characterized by its Resist CR coating, which provides a matte-silver finish and hard chrome plating for enhanced durability. The runner block body is crafted from unalloyed steel CS, ensuring robust performance in demanding applications. With a preload class C, this model is preload-free, ensuring smooth movement without initial tension. It falls into the high accuracy class H, signifying its suitability for applications requiring precise positioning. The inclusion of a ball chain facilitates quiet and smooth operation with optimal travel behavior. The runner block comes pre-lubricated and preserved with roller bearing grease Dynalub, reducing maintenance requirements. This model has an overall length of 72 mm and can be used interchangeably with guide rails of every accuracy level within the same size category. It boasts excellent dynamic characteristics and load ratings in all four main directions of loading, making it ideal for scenarios with high torsional moments on rails. Its design includes optimized entry-zone geometry and a high number of balls to minimize variation in elastic deflection. The B.RUNNER BLOCK CR KWD-020-BNS-C0-H-1 features end-face fastening threads for versatile mounting options and additional mounting screw holes at the center for increased rigidity under lift-off and side loading conditions. Its maximum permissible ambient temperature ranges from -10°C to +100°C, accommodating various operational environments. This ball runner block's static load rating C0 and dynamic load capacity ensure it can handle significant forces while maintaining stability and performance. The product's dimensions include a width of 63 mm (size E profiled rail systems) and height with guide rail at 36 mm. In summary, this Bosch Rexroth ball runner block is engineered to deliver superior performance in linear motion systems where precision, durability, and reliability are critical.
