The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-SNS-C0-N-1 (R163229420) is a high-precision aluminum ball runner block designed for use in lightweight design applications and for compensating low tolerances in connected structures. This runner block features a slimline width, standard length, and height format (SNS), and is made from aluminum to reduce weight without sacrificing precision. It is preload-free (preload class C) and offers standard accuracy (accuracy class N), ensuring optimal performance without the need for a ball chain. With an optimized entry zone geometry and a high number of balls, the B.RUNNER BLOCK AL KWD-025-SNS-C0-N-1 minimizes variations in elastic deflection. Its extra-compact design results in less gravity impact compared to steel runner blocks. The patented entry zone increases travel accuracy by up to six times, making it suitable for all SNS ball guide rails. The product comes pre-lubricated with roller bearing grease Dynalub and has a straight lube connection that is loosely attached. It allows for easy attachment from above without additional elements on the left or right front reference edges. The block's body is of the standard version, with an overall length specified by Bosch Rexroth. This runner block boasts excellent dynamic characteristics and supports minimum quantity lubrication with an integrated reservoir for oil lubrication. It has predesigned holes for pinned fitting, enabling greater parallelism and height offsets of mounting bases. Long-term lubrication over several years is possible, enhancing its maintenance-friendly profile. Interchangeability is limitless within each accuracy class as it can be combined with all ball guide rail systems offered by Bosch Rexroth. The product can withstand a broad range of ambient temperatures (specific min/max values provided by the manufacturer), making it suitable for diverse operating conditions. In summary, the Bosch Rexroth B.RUNNER BLOCK AL KWD-025-SNS-C0-N-1 (R163229420) offers maximum precision, lightweight design benefits, and compatibility across various guide rails within its accuracy classes—ideal for robust yet precise linear motion applications in machine building and robotics.
