The Bosch Rexroth B.RUNNER BLOCK AL KWD-035-FNS-C1-H-1 (R163131320) is a high-precision aluminum ball runner block designed for linear motion applications where reduced weight and high accuracy are essential. This runner block, part of the Ball Rail Systems, offers a compact design with a size format FNS featuring standard width, flange, normal length, and standard height. It is manufactured with a low preload class C and an accuracy class H for highly precise operations. The B.RUNNER BLOCK AL KWD-035-FNS-C1-H-1 is notable for its lightweight aluminum body which contributes to less gravity impact compared to steel versions. It does not include a ball chain but comes pre-lubricated with roller bearing grease Dynalub, ensuring smooth operation from the outset. The product has been designed without attachment elements on the left or right front reference edges and includes a straight lube connection that is loosely attached. This runner block boasts optimized entry zone geometry and an increased number of balls to minimize variations in elastic deflection. Its extracompact design allows for lightweight construction while compensating for low tolerances in connected structures. The patented entry zone significantly improves travel accuracy by up to six times and supports all SNS ball guide rails. For enhanced rigidity under liftoff and side loading conditions, the runner block includes two additional mounting screw holes at its center. Attachments can be mounted from both above and below the runner block, providing flexibility in integration. Additionally, it offers limitless interchangeability within each accuracy class across all Ball Rail Systems. The B.RUNNER BLOCK AL KWD-035-FNS-C1-H-1 is equipped with predesigned holes for pinned fitting which aids in achieving greater parallelism and height offsets during installation. Its dynamic load capacity C and dynamic torsional moment load capacity Mt ensure it can handle significant forces during operation, making it suitable for various industrial applications requiring long-term lubrication over several years for sustained performance.
