The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C1-X-1 (R165131822) is a highly precise ball runner block designed for linear motion applications requiring extreme precision and rigidity. This runner block boasts a steel CS body and is categorized as size 35 with an FNS format, indicating a flange width, normal length, and standard height. It features an extra precision accuracy class (XP) and a low preload (class C), ensuring smooth motion with minimal frictional oscillations, particularly under external loads. The product comes equipped with a ball chain that contributes to its low noise level and optimal travel behavior. The runner block's design includes integrated all-around sealing for protection against contaminants, enhancing its longevity and reliability in various operating environments. High torque load capacity is provided, along with different preload classes to suit specific application requirements. In terms of mounting flexibility, the B.RUNNER BLOCK CS allows attachments to be mounted from both above and below, thanks to its endface fastening thread. The optimized entry zone geometry coupled with a high number of balls reduces the variation in elastic deflection, which contributes to the unit's high rigidity that can support applications using just one runner block per rail. Additional features include two extra mounting screw holes at the center for improved rigidity under lift-off and side loading conditions, as well as an optional integrated inductive measuring system for wear-free operation. Pre-lubrication at the factory promises long-term lubrication capabilities over several years without the need for frequent maintenance. This Bosch Rexroth ball runner block is compatible with all SN/SNO ball guide rails and maintains high load ratings in all four main loading directions. Its dynamic load capacity and static longitudinal moment load capacity ensure it can withstand demanding tasks while maintaining maximum system rigidity due to its pre-tensioned O-arrangement.
