The Bosch Rexroth B.RUNNER BLOCK AL KWD-030-FNS-C1-H-1 (R163171320) is a high-precision aluminum ball runner block designed for linear motion applications requiring compact, lightweight, and highly accurate guidance systems. This runner block is part of the Ball Rail Systems product group and is distinguished by its reduced weight due to the aluminum construction while maintaining high load capacities in all main loading directions. Featuring size 030 with a flange width, normal length, and standard height (FNS format), this runner block offers low preload (Preload class C) and high accuracy (Accuracy class H), ensuring smooth and precise movements. It comes without a ball chain but includes initial lubrication and preservation for immediate use. The runner block's design allows for easy lubrication through straight lube connections that are loosely attached. The B.RUNNER BLOCK AL KWD-030-FNS-C1-H-1 boasts an optimized entry zone geometry and a high number of balls to minimize variation in elastic deflection. Its extra compact design contributes to less gravity impact compared to steel versions, making it ideal for lightweight designs or when compensating low tolerances in connected structures. The product also features improved rigidity under liftoff and side load conditions due to additional center mounting screw holes. The Bosch Rexroth runner block is designed for interchangeability, allowing it to be combined with all SNS ball guide rails within each accuracy class. It supports minimum quantity lubrication with an integrated reservoir for oil lubrication, which along with its prelubrication at the factory, enables long-term maintenance-free operation. Predrilled holes facilitate pinned fitting for enhanced parallelism and height offsets of mounting bases. This ball runner block operates quietly thanks to its well-designed ball return and guideway system. It is capable of enduring several years of service without the need for re-lubrication, making it a reliable component in various linear motion applications.
