The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-S-1 (R165141122) is a highly precise ball runner block designed for linear motion applications that demand super precision and rigidity. This runner block features a size format FNS with a flange width, normal length, and standard height. It is constructed from unalloyed steel CS, ensuring durability and strength. The low preload class C and accuracy class SP indicate its ability to provide smooth movement with minimal play and exceptional precision. Equipped with a ball chain, the runner block offers quiet operation and optimal travel behavior. The initial lubrication and preservation are provided by Roller bearing grease Dynalub, which contributes to the maintenance of the system over time. The straight lube connection is loosely attached for ease of maintenance. This runner block does not include attachment elements on either front reference edge but allows attachments to be mounted from both above and below. Its design includes an integrated all-around sealing system that protects against contaminants, thereby extending the product's lifespan. The optimized entry zone geometry combined with a high number of balls minimizes variations in elastic deflection, enhancing load capacity in all directions. This enables applications to potentially use just one runner block per rail without compromising performance. Additional mounting screw holes at the center increase rigidity under various loading conditions. For applications requiring precise measurements, an optional integrated inductive measuring system is available. The product is prelubricated at the factory for immediate use upon installation and is compatible with all SNSSNO ball guide rails by Bosch Rexroth. This model boasts high load ratings in all main loading directions and offers long-term lubrication options for extended operational periods without frequent maintenance needs. Its design ensures maximum system rigidity through a preloaded O-arrangement, making it suitable for various industrial applications where precision linear movement is critical.
