The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-CNS-C0-N-1 (R167259422) is a precision ball runner block designed for linear motion applications requiring high load capacity and rigidity. This runner block is part of the ball rail system, featuring a compact width (CNS format), normal length, and standard height. It is constructed from unalloyed steel CS for durability and comes with a preload class C, indicating it is preload-free. The accuracy class N ensures standard precision across applications. The B.RUNNER BLOCK CS KWD-020-CNS-C0-N-1 has an integrated ball chain that facilitates smooth, quiet travel behavior and contributes to the unit's excellent dynamic characteristics. It offers long-term lubrication capabilities over several years, enhancing the maintenance-free operation. The runner block body's overall length is tailored to provide high torsional moment load capacity, making it suitable for use in areas with restricted lateral space. This model boasts an all-around sealing feature for improved protection against contaminants, two additional mounting screw holes at the center for increased rigidity under liftoff and side loading conditions, and end-face fastening threads for attachments. The optimized entry-zone geometry along with a high number of balls reduces variation in elastic deflection while allowing the same high load ratings in all four main directions of loading. The B.RUNNER BLOCK CS KWD-020-CNS-C0-N-1 can be combined with all BNS ball guide rails and comes pre-lubricated from the factory, ensuring immediate operational readiness upon installation. Its dynamic load capacity C and dynamic torsional moment load capacity Mt are determined as per DIN ISO standards. The permissible ambient temperature range for this product extends from -10°C to +100°C. This Bosch Rexroth runner block is designed to accommodate maximum permissible linear speeds and accelerations while maintaining low friction coefficients. It provides significant flexibility in design due to its wide range of accessories and compatibility with various profiled rail systems specified by size (N, S, E, H, K) and tolerance dimensions provided in mm.
