The Bosch Rexroth B.RUNNER BLOCK CR KWC-065-FLS-C1-H-2 (R165361360) is a highly precise and corrosion-resistant ball runner block designed to meet the most demanding rigidity requirements in heavy machine construction. The runner block boasts a Resist CR coating for enhanced durability and a matte silver, hard chrome-plated body made of unalloyed steel CS. It features a low preload class C and high accuracy class H, contributing to its reliable performance in various applications. This model comes without a ball chain, is preserved but without initial lubrication, and does not include attachment elements on either the left or right front reference edges. The angular lube nipples are loosely attached for convenience. With an overall length of . mm, this runner block can be combined with guide rails of every accuracy level to support heavy-duty tasks with extreme load-bearing capacity. Further enhancing its capabilities are two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. The optimized entry-zone geometry along with a high number of balls reduces elastic deflection variation, ensuring quiet and smooth operation. Pre-lubricated at the factory, this product is designed for long-term lubrication over several years. The Bosch Rexroth B.RUNNER BLOCK CR is also notable for its ability to withstand a wide range of ambient temperatures from min ... max °C (admissible for short periods). It has an impressive dynamic load capacity C and can handle significant dynamic torsional moment load capacities Mt. Its design allows attachments to be mounted from both above and below, adding to its versatility in use. For protection against contaminants such as dirt, chips, and coolants that could reduce service life, this model incorporates seals like the standard SS seal for universal protection or specialized seals like LS for low friction requirements or DS for increased exposure to media. These components ensure that the ball runner block remains operational even in challenging environments while maintaining ease of movement and effective sealing as required by specific applications.
