The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-H-1 (R162121320) is a high-precision ball runner block designed for applications requiring restricted space in the transverse direction and high rigidity. The runner block body is made of carbon steel (CS), tailored for size with a slimline width, normal length, and high height. It offers low preload (class C) and high accuracy (class H), ensuring maximum precision without the inclusion of a ball chain. This runner block is prelubricated with roller bearing grease Dynalub, promoting long-term lubrication over several years. The design features an endface fastening thread compatible with various attachments and allows for smooth, quiet operation due to its optimally designed ball return and guideway. The product's dynamic characteristics are enhanced by its ability to significantly reduce frictional oscillations and maintain a low friction force level, especially under external load. The B.RUNNER BLOCK CS KWD-025-SNH-C1-H-1 boasts a patented entry zone that increases travel accuracy by up to six times compared to standard offerings. Its robust construction enables it to handle high torque loads efficiently while maintaining rigidity in all load directions, which can permit the use of just one runner block per rail in certain applications. This ball runner block is fully interchangeable within each accuracy class of Bosch Rexroth's Ball Rail Systems, providing flexibility when combining different components. Additionally, it can be used across all SN/SNO Ball Guide Rails, further expanding its applicability. The product's operational temperature range is from minimum permissible ambient temperatures up to a maximum that should be consulted for negative temperatures. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C1-H-1 (R162121320) offers exceptional precision and rigidity for specialized linear motion applications where space is limited but demands on performance are not. Its design ensures longevity, reduced maintenance requirements due to effective sealing options, and versatile integration with existing rail systems.
