The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C0-N-1 (R163129420) is a high-precision ball runner block designed for use in lightweight design applications and for compensating low tolerances with connected structures. This aluminum runner block offers significant weight reduction compared to its steel counterparts while maintaining maximum precision. It is characterized by a flange width, normal length, and standard height, making it suitable for various industrial requirements. The B.RUNNER BLOCK AL KWD-025-FNS-C0-N-1 comes prelubricated with roller bearing grease Dynalub, ensuring smooth operation from the outset. It features an optimized entry zone geometry and a high number of balls to minimize variation in elastic deflection, enhancing travel accuracy up to six times. The block's design allows for improved rigidity under conditions of liftoff and side loading due to additional mounting screw holes at the center. This runner block boasts limitless interchangeability within each accuracy class, meaning it can be combined at will with all SNS ball guide rails. Its predrilled holes enable greater parallelism and height offsets of mounting bases, while the smooth ball return and guideway ensure quiet running. The product is available without a ball chain and comes without attachment elements on either reference edge. In terms of durability and maintenance, the B.RUNNER BLOCK AL KWD-025-FNS-C0-N-1 allows for long-term lubrication over several years due to its integrated reservoir for oil lubrication. Its design also accommodates self-alignment for compensation of misalignments, contributing to a more reliable performance in dynamic environments. Overall, this Bosch Rexroth ball runner block is an excellent choice for those seeking a durable, high-performance linear guide solution that combines lightweight construction with the ability to handle significant load capacities from all directions.
