The Bosch Rexroth B.RUNNER BLOCK CS KWE-030-FLS-C0-H-1 (R205B79320) is a high-precision, highly accurate ball runner block designed for linear motion applications requiring high rigidity and very high load capacities. This BSCL ball runner block, with a size format of FLS (flanged, long, standard height), is constructed from unalloyed steel CS and is engineered to offer outstanding performance without preload clearance (Preload class C). It comes in the accuracy class H, indicating its highly precise nature. This runner block is notable for its overall length of . mm and its ability to be interchangeably combined with guide rails of every accuracy. It has been designed for mounting from both above and below and is compatible with Size T profiled rail systems, Size N with tolerance profiled rail systems of mm height, Size E, Size S, Size A profiled rail systems, and more. The product features a static load rating C0 and dynamic load capacities that ensure it can handle the demands of various linear motion tasks. Equipped with initial lubrication and preservation for maintenance-free operation at the start, the B.RUNNER BLOCK CS does not include a ball chain as part of its standard configuration. Its permissible ambient temperature range extends from min ... max °C short-term exposure. The runner block also boasts impressive dynamic longitudinal moment load capacity ML and dynamic torsional moment load capacity Mt. For those concerned about speed capabilities, this model offers a maximum permissible linear speed vmax. Additionally, it has been designed with standard seals (Seal SS) to ensure longevity and reliability in diverse operational environments. The weight specification stands at . kg for the nominal size provided. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWE-030-FLS-C0-H-1 offers superior precision in linear motion applications where rigidity and high-load capacity are essential. Its robust design and compatibility with various rail systems make it an ideal choice for demanding industrial uses.
