The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-N-1 (R165181422) is a precision ball runner block designed for linear motion applications requiring high rigidity and accuracy. This component is part of the company's comprehensive line of linear guides, known for their reliability and performance. The runner block body is constructed from unalloyed steel CS, ensuring durability and a long service life. Key specifications of this model include a low preload class C, indicating minimal pre-tensioning to reduce rolling resistance while maintaining system stability. It falls under accuracy class N, which signifies standard precision suitable for a wide range of applications. The product features an integrated ball chain that contributes to a quiet operation and optimal travel behavior. The B.RUNNER BLOCK CS is engineered with an optimized entry zone geometry and a high number of balls, minimizing variations in elastic deflection and enhancing travel accuracy by up to six times compared to standard systems. It boasts high rigidity in all load directions, allowing for the use of just one runner block per rail in certain applications. Additionally, it has improved rigidity under conditions of liftoff and side loading thanks to two extra mounting screw holes at the center. For versatility in installation, the runner block includes end-face fastening threads for attachments and lube fittings with metal threads on all sides. Its integrated all-around sealing system offers protection against contaminants, while its high torque load capacity makes it suitable for demanding operations. The B.RUNNER BLOCK CS comes pre-lubricated from the factory with roller bearing grease Dynalub 510, facilitating long-term lubrication over several years without maintenance. It can be used with all SN/SNO ball guide rails and offers equal high load ratings in all four main loading directions. This model does not include attachment elements on either front reference edge but allows attachments to be mounted from above or below the runner block body. With its comprehensive features tailored to enhance performance and longevity, this Bosch Rexroth ball runner block is positioned as an essential component in sophisticated linear motion systems where precision and reliability are paramount.
