The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-SLH-C0-H-1 (R162429370) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high rigidity. This model features a Resist CR coating that enhances its corrosion resistance, making it suitable for use in challenging environments. The runner block is constructed from unalloyed steel CS with a matte-silver, hard chrome-plated finish, ensuring durability and longevity. With an accuracy class of H (high) and being preload-free (preload class C), this ball runner block offers precise movement without any preload clearance. The lack of a ball chain contributes to the unit's streamlined design. Initial lubrication and preservation are provided, reducing the need for immediate maintenance upon installation. The ball runner block boasts excellent dynamic characteristics such as reduced frictional oscillations and low friction force levels, particularly under external loads. It also features a patented entry zone that significantly increases travel accuracy—up to six times—compared to standard systems. The product is designed for long-term lubrication over several years, minimizing maintenance requirements. This particular model has dimensions that cater to restricted space applications in the transverse direction while providing higher rigidity than similar products in its category. It supports high torque load capacities and maintains the same high load ratings in all four main directions of loading. Attachments can be mounted from above due to the end-face fastening thread, offering flexibility during assembly. Additionally, the Bosch Rexroth B.RUNNER BLOCK CR KWD-025-SLH-C0-H-1 comes prelubricated from the factory, streamlining installation procedures. Overall, this product is well-suited for applications demanding maximum precision, longevity in harsh conditions, and versatile mounting options within material profiled rail systems that have specific size requirements such as N, E, S, A with tolerance profiled rail systems ranging from 15 mm to 55 mm in height of runner block with guide rail specifications.
