The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C0-H-1 (R167229322) is a high-precision ball runner block designed for linear motion applications requiring compactness, high accuracy, and free movement without preload. This runner block is part of the CNS series, which indicates a compact width, normal length, and standard height configuration. The body of the runner block is constructed from unalloyed steel CS, ensuring durability and strength. Featuring an accuracy class H for highly accurate movement and a preload class C indicating that it is preload-free, this product is equipped with a ball chain that facilitates quiet and smooth motion. The runner block comes pre-lubricated with Dynalub grease to ensure long-term lubrication over several years and has initial preservation to maintain its condition until deployment. This model does not include attachment elements on either front reference edge but does offer the convenience of a straight lube connection loosely attached. With an overall length of . mm, the B.RUNNER BLOCK CS KWD-025-CNS-C0-H-1 allows for interchangeability with guide rails across various accuracies. Its design caters to applications facing high torsional moments on rails where lateral space may be limited. The runner block can handle high load ratings in all four main loading directions and has been optimized for improved rigidity under lift-off and side-loading conditions. This is further enhanced by two additional mounting screw holes at the center of the block. The ball runner block's all-around sealing provides protection in diverse environments, while its optimized entry-zone geometry ensures minimal variation in elastic deflection during operation. Its preloaded O-arrangement contributes to maximum system rigidity, making it suitable for use as an individual guide in demanding applications. This Bosch Rexroth product also boasts excellent dynamic characteristics with a very high torsional moment load capacity and resistance to torsion. It can be used with all BNS ball guide rails and offers a wide range of compatible accessories for versatile application needs.
