The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-BNS-C0-H-1 (R16712937Z) is a high-precision, corrosion-resistant ball runner block designed for linear motion systems. Its Resist CR coating ensures durability and protection against harsh environments. The runner block body is constructed from unalloyed steel CS with a matte-silver, hard chrome-plated finish, providing a robust and reliable foundation for various applications. This particular model boasts a wide format (BNS), normal length, and standard height, offering versatility for different installation requirements. It is preload-free (preload class C) and falls under the high accuracy class H, ensuring precise movement and alignment for demanding tasks. The absence of a ball chain simplifies the design while maintaining performance. The B.RUNNER BLOCK CR comes with initial lubrication and preservation, utilizing Roller bearing grease Dynalub to maintain smooth operation over time. It features an overall length of . mm and can withstand high torsional moments, making it suitable for use where significant torque loads are present. The optimized entry-zone geometry coupled with a high number of balls reduces elastic deflection variation. Attachments can be mounted both above and below the runner block due to its end-face fastening thread design. Additionally, two extra mounting screw holes at the center enhance rigidity under liftoff and side loading conditions. This ball runner block is compatible with all BNS ball guide rails, allowing for maximum system rigidity through a preloaded O-arrangement. It comes prelubricated from the factory to ensure immediate operation upon installation. In summary, the Bosch Rexroth B.RUNNER BLOCK CR KWD-025-BNS-C0-H-1 offers exceptional load capacity in all four main directions of loading, dynamic characteristics, and resistance to torsion—ideal for individual guides in material profiled rail systems requiring precise linear motion control.
