The Bosch Rexroth B.RUNNER BLOCK CR KWC-020-SNN-C0-H-2 (R169489360) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications requiring a slimline width, normal length, and low height configuration. This model boasts a Resist CR coating on its unalloyed steel CS body, providing enhanced durability and resistance to harsh conditions. The runner block operates with high accuracy (class H) and is preload-free (class C), ensuring smooth motion without excessive preload forces. This particular runner block does not include a ball chain, which simplifies the design and maintenance. It comes preserved but without initial lubrication, allowing users to apply their preferred lubricant based on specific application needs. The angular lube nipples are supplied loosely for easy attachment. The overall length of the runner block is specified in the product details. The B.RUNNER BLOCK CR KWC-020-SNN-C0-H-2 offers excellent dynamic characteristics, including reduced frictional oscillations and a low friction force level, especially under external loads. Its patented entry zone significantly increases travel accuracy by up to six times compared to standard models. Designed for long-term lubrication over several years, it also features an end-face fastening thread that accommodates various attachments. With its hard chrome-plated finish, the runner block has an appealing matte-silver appearance and provides reliable performance in environments with restricted upward and longitudinal space constraints. It is compatible with size E profiled rail systems and can withstand dynamic load capacities as defined by DIN ISO standards. The unit's low noise level and exceptional travel behavior make it suitable for applications demanding maximum precision and minimal disturbance. The Bosch Rexroth B.RUNNER BLOCK CR KWC-020-SNN-C0-H-2 is capable of self-aligning to compensate for misalignments without requiring additional self-alignment mechanisms. It supports maximum accelerations and permissible linear speeds as indicated in its technical specifications while operating within a broad range of ambient temperatures. This model also features standard seals (SS) for protection against contaminants such as dirt, chips, and coolants, ensuring prolonged service life even in challenging conditions.
