The Bosch Rexroth B.RUNNER BLOCK CS KWE-035-FNS-C1-N-1 (R205A31420) is a precision-engineered BSCL ball runner block designed for reliable linear motion in various applications. This component boasts a size 35 flanged runner block body made from unalloyed steel CS, ensuring durability and robustness in operation. It is characterized by a low preload class C and standard accuracy class N, without the inclusion of a ball chain. The runner block comes with initial lubrication and preservation for immediate use. With an overall length of the runner block specified, this product is designed to be interchangeable with guide rails of every accuracy level, providing flexibility in assembly and maintenance. Its high load capacity makes it suitable for applications with normal rigidity requirements, while the ability to mount from both above and below offers versatility in design integration. The B.RUNNER BLOCK CS KWE-035-FNS-C1-N-1 operates efficiently within a permissible ambient temperature range, maintaining performance even under varying environmental conditions. The stated friction coefficient indicates its smooth operation without seal friction. The product also features a static load rating C0 and dynamic load rating C, indicative of its ability to handle both static and dynamic forces effectively. This model is part of Bosch Rexroth's profiled rail systems, compatible with various sizes including Size B, H, K, N, T, E, A, V and S profiled rail systems as indicated by the specifications provided. It has been engineered to accommodate maximum acceleration and permissible linear speeds while ensuring longevity through its initial lubrication. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWE-035-FNS-C1-N-1 is an essential component for precise linear motion control in industrial applications where high performance and reliability are required.
