The Bosch Rexroth B.RUN. BLOCK NRFG KWD-020-SNS-C0-H-0 (R201189314) is a high-precision ball runner block designed for demanding applications requiring corrosion resistance and high accuracy. This model is particularly suitable for the packing industry and food industry subsectors, where materials must withstand harsh environments. The runner block features a slimline width, normal length, and standard height configuration (SNS format), with all steel components made from corrosion-resistant steel according to DIN standards. With an accuracy class of H for high precision and a preload class of C indicating it is preload-free, this runner block ensures smooth operation without initial lubrication or preservation. It lacks a ball chain and attachment elements on both left and right front reference edges, offering straightforward integration into various systems. The overall length of the runner block is specified at 70 mm. This Bosch Rexroth ball runner block stands out with its excellent dynamic characteristics, supporting the same high load ratings in all four main loading directions. It can be used on all SNS ball guide rails and offers long-term lubrication capabilities that can extend over several years. Additionally, the lube fittings come with metal threads for durability. The system's interchangeability is limitless; it allows combination with any ball guide rail system within each accuracy class, ensuring maximum system rigidity due to its preloaded O-arrangement. The design also includes an end-face fastening thread for all attachments and integrated all-around sealing to protect against contaminants. Furthermore, this model boasts optimized entry-zone geometry and a high number of balls to minimize variation in elastic deflection while providing smooth, quiet operation. Attachments can be easily mounted from above on the runner block body which comes in a standard version. In summary, the Bosch Rexroth B.RUN. BLOCK NRFG KWD-020-SNS-C0-H-0 (R201189314) offers exceptional performance in terms of load capacity, rigidity, durability, and ease of maintenance—ideal for applications that demand reliability and precision in challenging environments.
