The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C1-P-1 (R165111222) is a high-precision ball runner block designed for linear motion applications demanding rigidity, precision, and smooth travel behavior. This model features a size 15 flanged runner block made of unalloyed steel CS with a precision accuracy class P and low preload class C, ensuring reduced frictional oscillations and low friction levels even under external loads. The runner block is equipped with a ball chain to facilitate quiet operation and optimal travel performance. The product's optimized entry-zone geometry coupled with a high number of balls significantly minimizes variation in elastic deflection, enhancing travel accuracy up to six times compared to standard systems. It offers high rigidity across all load directions, which allows for the use of just one runner block per rail in certain applications. The design also includes two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. For maximum system rigidity, the ball runner block features a pre-tensioned O-arrangement. It comes pre-lubricated from the factory with Roller bearing grease Dynalub, facilitating long-term lubrication over several years without the need for frequent maintenance. This model can be used on all Bosch Rexroth SNS/SNO ball guide rails and boasts high load ratings in all four main loading directions. Furthermore, it incorporates an integrated all-around sealing system to protect against contaminants and offers various seal options such as SS (Standard seal), LS (Low-friction seal), DS (Double-lip seal), and FKM seals for extreme environments, ensuring extended service life even in challenging conditions. The B.RUNNER BLOCK CS KWD-015-FNS-C1-P-1 is suitable for applications that require maximum precision and rigidity while maintaining low noise levels and ease of movement. Its comprehensive design allows for attachments from above or below the runner block body, providing flexibility in system integration.
