The Bosch Rexroth B.RUNNER BLOCK CR KWC-055-FLS-C1-H-2 (R165351360) is a high-precision, corrosion-resistant ball runner block designed for demanding applications requiring maximum rigidity and load-bearing capacity. This model features the Resist CR coating, enhancing its durability and resistance to harsh environments. With an accuracy class of H (high) and a preload class of C (low preload), it ensures precise movement and smooth operation under various loading conditions. The B.RUNNER BLOCK CR is constructed from unalloyed steel CS with a matte silver, hard chrome-plated finish. It is designed without a ball chain, allowing for quiet and smooth motion while minimizing elastic deflection variations due to its optimized entry-zone geometry and high ball count. The block body's standard version has an overall length of . mm, accommodating heavy machine construction needs. This runner block is prelubricated at the factory for long-term lubrication over several years, reducing maintenance requirements. It also features improved rigidity under lift-off and side-loading conditions due to two additional central mounting screw holes. Attachments can be mounted from both above and below the runner block, providing flexibility in system design. The B.RUNNER BLOCK CR KWC-055-FLS-C1-H-2 is part of the Size E profiled rail systems with a static load rating C0 and dynamic torsional moment load capacity Mt suitable for heavy-duty applications. Its self-aligning capabilities allow compensation for misalignments without requiring additional self-alignment mechanisms. The product is preserved but comes without initial lubrication or attachment elements on the front reference edges. Designed to work seamlessly with guide rails across all accuracy classes, this Bosch Rexroth ball runner block meets the requirements for robustness in complex linear motion tasks where precision and long service life are critical.
