The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-CNS-C0-H-1 (R16722937Y) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high load capacities. This model features a Resist CR coating, ensuring durability and longevity in challenging environments. The runner block body is made of unalloyed steel CS with a matte silver finish, hard chrome plated for additional resistance to wear and tear. With an accuracy class H for high precision and preload class C indicating it is preload-free, this runner block ensures smooth motion without excess friction. The inclusion of a ball chain allows for consistent recirculation of the balls, contributing to the unit’s quiet operation and reduced variation in elastic deflection. It also comes prelubricated with roller bearing grease Dynalub, which helps maintain optimal performance over time. The B.RUNNER BLOCK CR KWD-025-CNS-C0-H-1 is characterized by its compact width (CNS format), standard height, and normal length. It has excellent dynamic characteristics capable of handling high torsional moments and provides the same high load ratings in all four main directions of loading. Its optimized entry-zone geometry maximizes the number of balls to enhance load capacity and reduce deflection variability. This runner block is compatible with all BNS ball guide rails, allowing for interchangeability across different accuracy levels. It offers maximum system rigidity due to its preloaded O-arrangement, while additional mounting screw holes at the center improve rigidity under liftoff and side loading conditions. Suitable for applications where space is limited laterally but high torsional moments are present, this product can operate within an ambient temperature range from -10°C to +100°C (short-term permissible), making it versatile across various operating conditions. The product group ID is 23; it has a nominal size of 25; its static load rating C0 and dynamic load ratings are determined as per DIN ISO standards based on 100 km travel distance.
