The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-P-1 (R165122222) is a precision-engineered ball runner block designed to meet the demands of high rigidity and precision applications. This runner block embodies a size 25 profile with an FNS format, indicating a width with flange, normal length, and standard height. The body is constructed from unalloyed steel CS, ensuring durability and reliability. The B.RUNNER BLOCK CS features a medium preload (class C) and boasts precision accuracy (class P), delivering consistent performance even under varying load conditions. It comes equipped with a ball chain that facilitates low noise operation and optimal travel behavior. The initial lubrication and preservation are applied at the factory, utilizing Roller bearing grease Dynalub for long-term maintenance-free operation. With an overall length of . mm, this runner block is interchangeable with guide rails across every accuracy class, enhancing its versatility in different setups. It's particularly suited for applications that require significantly reduced frictional oscillations, low friction force levels under external loads, and maximum travel accuracy—thanks to its patented entry zone which can increase travel accuracy up to six times. The design includes a straight lube connection loosely attached for easy maintenance and high torque load capacity due to its robust construction. Additionally, the optimized entry-zone geometry coupled with a high number of balls minimizes variation in elastic deflection. The ball runner block also features high rigidity in all load directions allowing for use with just one runner block per rail if necessary. For enhanced system rigidity, the B.RUNNER BLOCK CS includes two additional mounting screw holes at the center of the block and supports attachments from both above and below. Its integrated all-around sealing protects against contaminants while maintaining performance integrity over time. This Bosch Rexroth ball runner block can be used on all SNS/SNO ball guide rails and maintains high load ratings in all four main loading directions. It represents an ideal solution for those seeking long-term lubrication options over several years without compromising on system precision or performance.
