The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C0-H-1 (R163129320) is a state-of-the-art aluminum ball runner block designed for high precision and lightweight applications. Its aluminum construction significantly reduces weight without compromising on accuracy or load capacity. This model is part of the FNS series, which denotes its flanged width, normal length, and standard height. With a preload class of C, it is preload-free, and its high accuracy class H ensures exceptional precision in operation. The runner block body is constructed from aluminum for reduced weight and features an optimized entry zone geometry along with a high number of balls to minimize variation in elastic deflection. It boasts an extracompact design that offers less gravitational impact than steel equivalents, making it ideal for designs where weight is a critical factor. The patented entry zone increases travel accuracy by up to six times compared to conventional designs. This runner block can be used with all SNS ball guide rails and offers improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at the center. Attachments can be mounted from both above and below the block, providing versatility in integration. It ensures limitless interchangeability within each accuracy class across all ball rail systems. Pre-lubricated at the factory with roller bearing grease Dynalub, this model comes with an integrated reservoir for oil lubrication that allows for minimum quantity lubrication. The predrilled holes facilitate pinned fitting for enhanced parallelism and height offsets of mounting bases. Designed for smooth and quiet operation, this runner block has optimal ball return and guidance features. It supports long-term lubrication over several years without the need for frequent maintenance. The absence of a ball chain standardizes the design while still ensuring dynamic performance across various applications.
