The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-H-1 (R165121320) is a high-precision ball runner block designed for linear motion applications requiring rigidity, precision, and smooth movement. It features a size 25 flange width, normal length, and standard height with a runner block body made of unalloyed steel CS. The low preload class C and high accuracy class H ensure minimal friction and maximum travel accuracy. This model does not include a ball chain but comes with initial lubrication and preservation for immediate use. The B.RUNNER BLOCK CS is notable for its dynamic characteristics and reduced frictional oscillations under external load, which contribute to its high precision. Its patented entry zone enables up to six times increased travel accuracy. The design allows attachments to be mounted from above or below, with metal-threaded lube fittings on all sides and end-face fastening threads for various attachments. Integrated all-around sealing protects against contaminants while maintaining system rigidity. This runner block can be used with all SN/SNO ball guide rails and offers long-term lubrication capabilities spanning several years without the need for maintenance. It supports high load ratings in all four main directions of loading due to its design that includes two additional mounting screw holes at the center for enhanced rigidity under lift-off and side loading conditions. The Bosch Rexroth ball runner block is interchangeable with guide rails of every accuracy level, making it versatile for different setups. It is suitable for applications where high rigidity requirements are essential, such as in machine tools or automation systems where precise movement is critical. Optional features include an integrated inductive measuring system that provides wear-free operation for extensive periods.
