The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C1-N-1 (R165321421) is a high-precision ball runner block designed for linear motion applications requiring exceptional rigidity and accuracy. This runner block features a size 25 flange-long-standard (FLS) format, with an unalloyed steel CS body that ensures durability and consistent performance. It is classified under preload class C, indicating a low preload for reduced system rigidity without compromising on smooth movement. Additionally, the product falls under accuracy class N, which signifies standard precision levels suitable for a wide range of applications. The B.RUNNER BLOCK CS is devoid of a ball chain and comes with initial lubrication and preservation to extend its service life. Its design includes straight lube connections that are loosely attached for ease of maintenance. The overall length of the runner block is optimized to provide reliable operation within its specified dimensions. Notably, this ball runner block can be interchanged with guide rails across all accuracy levels, making it highly versatile for different setups. It boasts excellent dynamic characteristics such as reduced frictional oscillations and low friction force levels, especially under external loads. The patented entry zone enhances travel accuracy by up to six times. For extended periods of operation without the need for re-lubrication, this model offers long-term lubrication capabilities spanning several years. The device features metal-threaded lube fittings on all sides, end-face fastening threads for various attachments, and an integrated all-around sealing system that protects against contaminants. With high torque load capacity and multiple preload classes available, the B.RUNNER BLOCK CS provides high rigidity in all loading directions. It can be used effectively with just one runner block per rail due to its improved rigidity under lift-off and side loading conditions—aided by additional mounting screw holes at the center of the block. Overall, this Bosch Rexroth ball runner block is prelubricated at the factory and engineered to meet demanding requirements in terms of precision motion control while maintaining maximum system rigidity through its preloaded O-arrangement design. Attachments can be mounted from both above and below the runner block, ensuring flexibility in various installation scenarios. It is compatible with all SN/SNO ball guide rails from Bosch Rexroth and maintains high load ratings in all principal loading directions.
