The Bosch Rexroth B.RUNNER BLOCK CS KWC-035-BNS-C0-N-2 (R167139410) is a high-precision ball runner block designed for linear motion applications that require high torsional moment load capacity and excellent dynamic characteristics. This runner block is part of the BNS series, featuring a wide format with standard height and length. Constructed from unalloyed steel CS, it offers standard accuracy (class N) and is preload-free (preload class C), ensuring smooth motion without excess friction. The B.RUNNER BLOCK CS has no ball chain, is preserved but comes without initial lubrication, and does not include attachment elements on either the left or right front reference edges. However, it does have angular lube nipples that are loosely attached. The body of the runner block is in a standard version, with an overall length specified by the manufacturer. This ball runner block boasts excellent dynamic characteristics such as low noise levels and optimal travel behavior. It has a high torque load capacity and can handle high loads in all four main loading directions. Attachments can be mounted from both above and below the runner block, which features an end-face fastening thread for all attachments. Notably, this model has been designed to be interchangeable with guide rails of every accuracy level within its series. The optimized entry zone geometry along with a substantial number of balls helps minimize variation in elastic deflection across its travel range. Its design also includes two additional mounting screw holes at the center to improve rigidity under lift-off and side loading conditions. The product group ID indicates its compatibility with various profiled rail systems specified by Bosch Rexroth. In terms of environmental adaptability, this runner block can operate within a permissible ambient temperature range as noted by the manufacturer but should be consulted for use at negative temperatures. The dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on DIN ISO standards for 100 km travel; however, these values can be adjusted based on actual stipulations as indicated in footnotes provided by Bosch Rexroth. Overall, the B.RUNNER BLOCK CS KWC-035-BNS-C0-N-2 is suited for applications requiring precise linear guidance with significant resistance to torsional loads while maintaining system rigidity and performance under various loading conditions.
