The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C3-U-1 (R16514392Y) is a ball runner block designed for ultra-precision and high rigidity applications. This component is part of the Ball Rail Systems product line, specifically engineered for dynamic and static load requirements. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength. It features a high preload class C, indicating a high degree of rigidity within the system which reduces elastic deflection. The accuracy class UP (Ultra Precision) signifies that this model provides exceptional travel accuracy, making it suitable for applications where precision is paramount. The ball chain included with this runner block contributes to low noise operation and smooth travel behavior. For maintenance ease, it comes with initial lubrication and preservation, using Roller bearing grease Dynalub. This model has been designed to accommodate a variety of attachments both above and below the runner block body thanks to its endface fastening thread. The all-around sealing integrated into the design offers protection against contaminants, thereby extending the service life of the runner block. Significant features include optimized entry-zone geometry and a high number of balls which work together to minimize variations in elastic deflection across different load conditions. The design also allows for improved rigidity under liftoff and side loading due to additional mounting screw holes at the center of the block. The B.RUNNER BLOCK CS KWD-045-FNS-C3-U-1 is compatible with all SN/SNO ball guide rails from Bosch Rexroth and supports high load ratings in all four main loading directions. It also offers options for long-term lubrication over several years without requiring frequent maintenance. In summary, this Bosch Rexroth Ball Runner Block is tailored for applications demanding maximum precision, rigidity under various loads, and longevity in challenging operating environments.
