The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-U-1 (R16518292Z) is a state-of-the-art ball runner block designed for ultra-precision linear motion applications. This high-performance component is crafted from unalloyed steel CS, ensuring durability and reliability. The runner block features a medium preload (class C) and boasts an ultra precision accuracy class (UP), making it ideal for tasks requiring exceptional precision. It does not include a ball chain but comes with initial lubrication and preservation, utilizing Roller bearing grease Dynalub for sustained performance. With dimensions tailored to size E profiled rail systems, the B.RUNNER BLOCK has an overall length that complements its robust design. It provides interchangeability with guide rails of varying accuracies, enhancing its versatility in different setups. The product is engineered to meet high rigidity requirements and exhibits excellent dynamic characteristics, including reduced frictional oscillations and low friction levels under external loads. The B.RUNNER BLOCK's patented entry zone significantly improves travel accuracy—up to six times—while its design allows attachments to be mounted from both above and below. Metal-threaded lube fittings on all sides facilitate easy maintenance, and additional mounting screw holes at the center improve rigidity under side loading conditions. The runner block also supports high torque loads and offers various preload classes for different application needs. This component is prelubricated at the factory for immediate use on all SN/SNO ball guide rails. Its integrated all-around sealing ensures long-term protection against contaminants, leading to several years of potential long-term lubrication without the need for frequent maintenance. The B.RUNNER BLOCK can withstand high load ratings in all four main loading directions, making it a versatile choice for diverse linear motion systems where maximum precision is paramount.
