The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-BNS-C0-H-1 (R167129370) is a highly precise ball runner block designed for linear motion applications requiring high accuracy and corrosion resistance. This runner block is notable for its Resist CR coating, which provides exceptional durability and resistance to environmental factors. It belongs to the BNS format, featuring a wide width, normal length, and standard height for versatile use in various systems. The runner block is constructed from unalloyed steel CS with a matte-silver hard chrome plating for added robustness. It comes preload-free (preload class C) and boasts a high accuracy class H, ensuring precise movements without the need for initial adjustments. The absence of a ball chain simplifies the design while maintaining smooth operation. Lubrication is provided by Roller bearing grease Dynalub, and the runner block arrives with initial lubrication and preservation applied. The product also features straight lube connections that are loosely attached for easier maintenance. This model offers excellent dynamic characteristics due to its optimized entry-zone geometry and a high number of balls, which minimizes variation in elastic deflection. It can withstand high torsional moments on rails, delivering consistent performance in all four main loading directions. The B.RUNNER BLOCK CR KWD-025-BNS-C0-H-1 has an overall length of . mm and is designed to be interchangeable with guide rails of every accuracy level. Additional features include end-face fastening threads for attachments that can be mounted from both above and below the block, contributing to maximum system rigidity due to its preloaded O-arrangement. Two extra mounting screw holes at the center enhance rigidity under lift-off and side loading conditions. This product is ideal as an individual guide in material profiled rail systems due to its very high torsional moment load capacity and excellent torsion resistance. It operates within an ambient temperature range of min ... max °C (admissible for short periods), making it suitable for various environments. With a static load rating C_0 and dynamic torsional moment load capacity Mt specified by DIN ISO standards, this ball runner block ensures reliable performance in demanding applications.
