The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-CNS-C0-H-1 (R16722937Z) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high load capacity. It is part of the product group ID 1 and falls under the size N category with a nominal size of 25, suitable for profiled rail systems with a tolerance of +/- mm. The runner block body is constructed from unalloyed steel CS, featuring a matte silver finish with hard chrome plating to provide exceptional durability and resistance to corrosive environments. This model boasts a compact width (CNS format), normal length, and standard height, ensuring compatibility with restricted lateral spaces while maintaining excellent dynamic characteristics. Its accuracy class H denotes a high level of precision, and it operates preload-free (preload class C), ensuring smooth motion without excess friction. The absence of a ball chain reduces complexity in the design while still offering superior performance. Equipped with initial lubrication and preservation, this runner block is prelubricated at the factory for immediate use. It can handle very high torsional moment load capacities due to its robust construction and additional mounting screw holes at the center, which also enhance rigidity under liftoff and side loading conditions. The optimized entry-zone geometry alongside an increased number of balls minimizes variation in elastic deflection. Designed for use on all BNS ball guide rails, this runner block ensures maximum system rigidity through its preloaded O-arrangement. It features end-face fastening threads for attachments that can be mounted from above, allowing for flexible installation options. Furthermore, it has a dynamic load capacity C based on 100 km travel as per DIN ISO 14728-1 standards and can operate within an ambient temperature range of -10°C to +100°C. The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-CNS-C0-H-1 is an ideal solution for applications demanding high precision motion control where space may be limited yet high torsional moments are expected.
