The Bosch Rexroth B.RUN. BLOCK NRFG KWD-025-SLS-C1-H-0 (R201221314) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This model is particularly suitable for the packaging industry as well as various subsectors of the food industry, where materials must meet stringent hygiene standards. The runner block comes in a slimline width (SLS), with a long length and standard height, ensuring a compact yet robust design that can handle dynamic loads effectively. This product features an overall length of 70.2 mm and boasts excellent dynamic characteristics, supporting high load ratings in all four main directions of loading. It is compatible with SNS ball guide rails, facilitating versatile use across different systems due to its limitless interchangeability within each accuracy class. The B.RUN. BLOCK NRFG KWD-025-SLS-C1-H-0 offers maximum system rigidity through its preloaded O-arrangement and end-face fastening thread for secure attachments. Constructed from corrosion-resistant steel compliant with DIN standards, it is engineered without a ball chain or initial lubrication to allow for customization based on application requirements. It also features an integrated all-around sealing system and optimized entry-zone geometry that minimizes variation in elastic deflection, ensuring smooth operation. The ball runner block's high rigidity enables applications with just one runner block per rail if needed, while its design allows for long-term lubrication over several years, reducing maintenance frequency. Attachments can be conveniently mounted from above the runner block, enhancing ease of assembly. With an accuracy class H (highly accurate) and preload class C (low preload), this Bosch Rexroth linear guide component ensures precise movements and reliable performance in demanding environments where precision and durability are critical.
