The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C2-X-1 (R165172822) is a premium ball runner block designed for high-precision linear movement applications. This component is part of the Ball Rail Systems product group and is characterized by its FNS size format, which indicates a flange width, normal length, and standard height. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength. With an accuracy class of XP (extra precision), this runner block delivers exceptional travel accuracy and is suitable for applications requiring maximum precision. The medium preload class C signifies an average preload that contributes to the system's rigidity while still allowing smooth movement. A key feature of this model is the ball chain which aids in reducing noise levels and enhancing travel behavior. The B.RUNNER BLOCK CS also boasts a straight lube connection loosely attached for easy maintenance, along with initial lubrication and preservation using Roller bearing grease Dynalub. It does not come with attachment elements on either front reference edge but offers flexibility for attachments to be mounted from above or below. Designed to meet high rigidity requirements, this runner block significantly reduces frictional oscillations and maintains a low friction force level even under external load conditions. Its patented entry zone increases travel accuracy by up to six times compared to conventional systems. Additional attributes include all-around sealing for protection against contaminants, high torque load capacity, and various preload classes to match different application needs. The optimized entry zone geometry coupled with a high number of balls minimizes variation in elastic deflection. This model can be used on all SNSSNO ball guide rails and supports the same high load ratings in all four main loading directions. It also allows long-term lubrication over several years without frequent maintenance requirements. The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C2-X-1 (R165172822) represents a top-tier solution for sophisticated linear motion tasks where precision and reliability are paramount.
