The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-CNS-C0-H-1 (R167259320) is a high-precision ball runner block designed for linear motion applications that demand high accuracy and rigidity. It features a compact width (CNS format), normal length, and standard height, and is constructed from unalloyed steel CS. This runner block is notable for its preload class C, indicating it is preload-free, and its accuracy class H for high precision. The absence of a ball chain signifies a standard design without the additional feature. This product includes an initial lubrication and preservation with roller bearing grease Dynalub, ensuring reduced maintenance requirements. The straight lube connection is loosely attached for ease of lubrication access. The runner block body comes in a standard version with an overall length specified by the manufacturer. The B.RUNNER BLOCK CS KWD-020-CNS-C0-H-1 boasts excellent dynamic characteristics and high torque load capacity, making it suitable for applications with high torsional moments on rails where lateral space may be restricted. It can sustain the same high load ratings in all four main directions of loading and allows for long-term lubrication over several years. Additional features include integrated all-around sealing to protect against contaminants, improved rigidity under lift-off and side-loading conditions due to two extra mounting screw holes at the center of the block, and compatibility with all BNS ball guide rails. It also offers a wide range of accessories, end-face fastening threads for various attachments, optimized entry-zone geometry for minimal elastic deflection variation, maximum system rigidity due to preloaded O-arrangement, very high torsional moment load capacity, and excellent torsion resistance. This runner block comes prelubricated from the factory to facilitate immediate use in various linear motion systems where precision and durability are crucial. The product's design ensures reliable performance even in demanding operational conditions while maintaining flexibility in terms of rail compatibility within the specified accuracy range.
