The Bosch Rexroth B.RUNNER BLOCK CS KWE-020-SNS-C1-N-1 (R205C81420) is a high-quality linear motion component designed for precision and reliability. This BSCL ball runner block is engineered for high load capacity applications where space is restricted in the transverse direction. It features a slimline, normal, standard height (SNS) format with a runner block body made of unalloyed steel CS. The product is characterized by its low preload class C and standard accuracy class N, ensuring smooth motion and consistent performance. With an overall length specific to the model, this runner block can be easily integrated into various systems. The lack of a ball chain simplifies the design while initial lubrication and preservation are included to facilitate immediate use upon installation. Its compatibility with every accuracy level of guide rails allows for flexible interchangeability in complex assemblies. The B.RUNNER BLOCK CS comes without seals, which results in a lower friction coefficient ranging from 0.01 to 0.02, contributing to efficient operation within permissible ambient temperatures of -10°C to +100°C. It has been designed for mounting from above and boasts impressive static and dynamic load capacities as well as torsional moment load capacities that vary depending on the size of the profiled rail systems it is paired with. This runner block also supports maximum accelerations and speeds when combined with appropriate forces, making it suitable for dynamic applications that demand both speed and precision. The product's robust construction ensures longevity even under challenging conditions, making it an essential component for sophisticated linear motion systems across various applications.
