The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-N-1 (R167221422) is a ball runner block designed for precision linear movement and is part of the company's extensive profiled rail systems. This runner block features a CNS format, which denotes a compact width, normal length, and standard height, making it suitable for applications where space is limited but high load capacity is required. The body of the runner block is made from unalloyed steel CS, ensuring durability and strength. The B.RUNNER BLOCK CS comes with a low preload class C and standard accuracy class N. It includes a ball chain to facilitate smooth motion and reduce noise levels during operation. The initial lubrication and preservation are provided to enhance performance longevity, with the roller bearing grease Dynalub contributing to consistent operation over time. This model has been designed without attachment elements on either front reference edge while featuring a straight lube connection that is loosely attached. Its overall length measures at an efficient size for various applications. The runner block boasts interchangeability features, allowing it to be combined with guide rails of varying accuracy without compatibility issues. In terms of technical capabilities, this runner block can handle high torsional moments on rails with restricted lateral space and provides the same high load ratings in all four main directions of loading. It offers long-term lubrication options spanning several years and exhibits excellent dynamic characteristics that include high torque load capacity. The design includes integrated all-around sealing and additional mounting screw holes to improve rigidity under liftoff and side loading conditions. The B.RUNNER BLOCK CS can accommodate attachments from above thanks to its endface fastening thread, while its optimized entry-zone geometry allows for minimal variation in elastic deflection during use. Overall, this product promises quiet operation, smooth running characteristics, maximum system rigidity due to its preloaded O-arrangement, very high torsional moment load capacity, and resistance against torsion – making it an ideal choice for various precision linear motion applications.
