The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C0-N-1 (R165189422) is a state-of-the-art ball runner block designed for linear guidance systems. This runner block is part of Bosch Rexroth's Ball Rail Systems and is constructed from unalloyed steel CS, ensuring durability and strength for demanding applications. The product features a size 20 with an FNS format, which denotes a standard width flange, normal length, and standard height. It boasts a preload class C indicating that it is preload-free, which ensures smooth motion without pre-tension. The accuracy class N signifies standard precision. Equipped with a ball chain, the B.RUNNER BLOCK CS provides low noise operation and optimal travel behavior. Its initial lubrication and preservation facilitate immediate use upon installation with the potential for long-term lubrication spanning several years. The runner block body comes in a standard version with an overall length of 100 mm. This model offers high rigidity to meet strict requirements and features significantly reduced frictional oscillations even under external loads. Its patented entry zone increases travel accuracy up to six times compared to conventional systems. Attachments can be mounted from both above and below the runner block, providing flexibility in various applications. The Bosch Rexroth B.RUNNER BLOCK CS has been designed to offer maximum precision and can withstand high torque loads due to its optimized entry-zone geometry and numerous balls that minimize elastic deflection variations. It is capable of handling high load ratings in all four main loading directions and allows for easy interchangeability with guide rails across different accuracy classes. Additional features include metal-threaded lube fittings on all sides for easy maintenance, integrated all-around sealing for protection against contaminants, end-face fastening threads for various attachments, two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions, and an optional integrated inductive measuring system that is wear-free. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C0-N-1 (R165189422) offers exceptional performance characteristics suitable for applications requiring precise movement control, high rigidity requirements, reduced friction levels, versatile mounting options, long-term reliability, and robust construction.
