The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C0-H-1 (R167229320) is a high-precision ball runner block designed for linear motion applications where compact size, high accuracy, and preload-free operation are essential. This runner block features a CNS format, indicating a compact width, normal length, and standard height. It is constructed from unalloyed steel CS to ensure durability and performance. The product is classified under preload class C, meaning it operates without preload, and falls under accuracy class H for high precision. Notably absent is the ball chain; however, the runner block does come with initial lubrication and preservation using Roller bearing grease Dynalub. The overall length of the runner block is specified in the product details. This Bosch Rexroth runner block stands out for its ability to handle high torsional moments on rails with limited lateral space while offering equal load ratings in all four main loading directions. It's capable of long-term lubrication over several years and exhibits excellent dynamic characteristics due to its optimized entry-zone geometry and a large number of balls that reduce variation in elastic deflection. Additional features include integrated all-around sealing for protection against contaminants, improved rigidity under lift-off and side loading conditions through two central mounting screw holes, and compatibility with all BNS ball guide rails. The end-face fastening thread allows for easy attachment of various accessories. The B.RUNNER BLOCK CS KWD-025-CNS-C0-H-1 boasts very high torsional moment load capacity and resistance to torsion. It is pre-lubricated at the factory for immediate use upon installation. Its profiled rail systems come in various sizes with specific tolerances, providing options suitable for different applications. The permissible ambient temperature range ensures reliable operation across diverse environments. In summary, this Bosch Rexroth ball runner block combines versatility with exceptional mechanical properties to meet the demands of sophisticated linear motion systems where precision and reliability are paramount.
