The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C2-SP-1 (R16511212Y) is a high-precision ball runner block designed for linear motion applications requiring super precision and medium preload. This runner block, part of the Ball Rail Systems product group, is characterized by its steel CS construction and FNS format, indicating a flange width, normal length, and standard height. It boasts an accuracy class of SP for super precision and comes equipped with a ball chain that ensures low noise levels and optimal travel behavior. With an average preload classified under preload class C, this runner block provides excellent rigidity for demanding applications. Its patented entry zone increases travel accuracy significantly—up to six times—making it ideal for situations where maximum precision is essential. The product also features an integrated all-around sealing system, high torque load capacity, and the ability to mount attachments from both above and below. The B.RUNNER BLOCK CS KWD-015-FNS-C2-SP-1 is prelubricated with roller bearing grease Dynalub at the factory for long-term lubrication potential over several years. It's designed to be used with all SN/SNO ball guide rails and can sustain the same high load ratings in all four main loading directions. Additionally, this model has optimized entry zone geometry coupled with a high number of balls to minimize variation in elastic deflection. The Bosch Rexroth runner block's robust design allows it to withstand significant static and dynamic loads while maintaining a low friction coefficient between 0.01 and 0.02. It can operate within an ambient temperature range of -10°C to +100°C (short-term permissible), ensuring reliable performance across various environments. This model does not include attachment elements on either front reference edge but does feature endface fastening threads for all attachments, lube fittings with metal threads on all sides, and additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. With its comprehensive features tailored for high rigidity requirements, this Bosch Rexroth ball runner block stands out as a versatile component in linear motion systems.
