The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C2-S-1 (R16514212Y) is a highly precise ball runner block designed for linear motion applications that require high rigidity and precision. This runner block features a size FNS format with a width flange, normal length, and standard height. It's constructed from unalloyed steel CS and offers super precision accuracy (class SP), along with an average preload (class C). The product is distinguished by its medium preload and ball chain, which ensures low noise levels and optimal travel behavior. The Bosch Rexroth B.RUNNER BLOCK is prelubricated with roller bearing grease Dynalub for initial use and has integrated all-around sealing to protect against contaminants. It also boasts high torque load capacity and the ability to handle significant external loads with reduced frictional oscillations. The patented entry zone of the runner block increases travel accuracy up to six times compared to standard blocks. Furthermore, this runner block can be used in various mounting configurations due to its straight lube connection and endface fastening threads, allowing attachments from both above and below. Its optimized entry zone geometry combined with a high number of balls minimizes variation in elastic deflection, enhancing rigidity in all load directions. This feature allows for applications that may only require one runner block per rail. Additional benefits include improved rigidity under liftoff and side loading conditions, thanks to two extra mounting screw holes at the center of the runner block. For systems requiring maximum rigidity, the preloaded O-arrangement is ideal. An optional integrated inductive measuring system provides wear-free operation for precise positioning tasks. This Bosch Rexroth ball runner block is compatible with all SN/SNO ball guide rails, ensuring high load ratings in all four main loading directions. Its design facilitates long-term lubrication over several years without maintenance, making it suitable for demanding environments where durability and reliability are critical.
