The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-H-1 (R16512232Y) is a high-precision ball runner block designed for linear motion applications where rigidity and accuracy are paramount. This runner block features size 25 with a flange width, normal length, and standard height, constructed from unalloyed steel CS. It boasts a medium preload class C and a high accuracy class H, ensuring precise movement and reliable performance. The ball chain included with the unit contributes to its low noise level and optimal travel behavior. The B.RUNNER BLOCK CS KWD-025-FNS-C2-H-1 is equipped with initial lubrication and preservation for maintenance-free operation over extended periods. The roller bearing grease Dynalub enhances the durability of the unit. It comes without attachment elements on both left and right front reference edges, but has straight lube connections that are loosely attached for easy maintenance. This model offers interchangeability with guide rails of every accuracy level, allowing for flexibility in system design. Its patented entry zone increases travel accuracy by up to six times compared to conventional designs. The runner block can be mounted from above or below, providing versatility in assembly configurations. Key features include an all-around sealing system for protection against contaminants, high torque load capacity, and the option for an integrated inductive measuring system for real-time position feedback. The optimized entry zone geometry along with a large number of balls minimizes elastic deflection variations under load. Suitable for use on all SN/SNO ball guide rails by Bosch Rexroth, this runner block supports high load ratings in all four main loading directions. It is designed to achieve maximum system rigidity through a preloaded O-arrangement and can withstand significant acceleration forces while maintaining precision. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-H-1 (R16512232Y) represents a robust solution for linear motion systems requiring high precision, rigidity, and long-term reliability without frequent maintenance needs.
