The Bosch Rexroth B.RUNNER BLOCK CS KWC-065-FNS-C3-P-2 (R165163210) is a high-precision ball runner block designed for linear motion and guidance systems. It is part of the Ball Rail Systems product line and specifically falls under the category of Ball Runner Blocks. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength for heavy-duty applications. It features a size designation that corresponds with its dimensions and form factor, identified as format FNS, which implies a flange width, normal length, and standard height. This model is characterized by a high preload class C, indicating it is preloaded to a higher degree for increased rigidity and reduced system play. It also belongs to accuracy class P for precision applications where exact movements are critical. Notably, this runner block does not come with a ball chain, an initial lubrication or attachment elements on the left or right front reference edges; however, angular lube nipples are loosely attached. The B.RUNNER BLOCK CS KWC-065-FNS-C3-P-2 excels in areas requiring high rigidity such as heavy machine construction due to its robust load-bearing capacity. Its design includes additional mounting screw holes at the center for enhanced rigidity under various loading conditions including liftoff and side loads. This model also supports high torque loads and features an innovative channel design that requires minimal lubrication quantities. For smooth operation, the ball return and guideway are optimally designed to ensure quiet running while minimizing elastic deflection variations through optimized entry-zone geometry and a high number of balls. The runner block can be used with all SNS Ball Guide Rails offering limitless interchangeability among various guide rail versions. In terms of maintenance and customization, different preload classes are available along with end-face fastening threads for attachments which can be mounted from both above and below the block. The product is preserved but comes without initial lubrication. Its dynamic load capacity C along with static longitudinal moment load capacity ML ensures reliable performance across varied operational conditions within permissible ambient temperature ranges specified in the detailed technical data.
