The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 (R167221320) is a high-precision ball runner block designed for linear motion applications that require compactness, high load capacity, and precision. This runner block is part of the Ball Rail Systems product group and offers a comprehensive solution for guided linear movements. It features a steel CS body with a size N, providing a robust structure suitable for various applications. The runner block's design includes four rows of balls with point contact, ensuring minimal friction and optimal movement in all loading directions. The preload class C signifies a low preload, while the accuracy class H indicates high precision. Notably, this model does not come with a ball chain but includes initial lubrication and preservation to facilitate immediate use. One of the key capabilities of this runner block is its excellent dynamic characteristics, which include high load ratings in all four main directions of loading. It is equipped to handle high torsional moments on rails where lateral space is restricted. The optimized entry-zone geometry coupled with a significant number of balls reduces variation in elastic deflection, leading to maximum system rigidity. For enhanced durability and performance, the B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 features integrated all-around sealing and additional mounting screw holes at its center for improved rigidity under lift-off and side-loading conditions. It can be used on all BNS Ball Guide Rails and supports various attachments that can be mounted from above. This model also boasts long-term lubrication capabilities spanning several years, reducing maintenance needs. Its design allows for self-aligning to compensate for misalignments without requiring self-alignment mechanisms. The product's dynamic load capacity C and other load capacities are determined as per DIN ISO standards. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 (R167221320) is an advanced linear motion component offering durability, precision, and versatility for demanding applications where space constraints exist yet high torsional loads are present.
