The Bosch Rexroth B.RUNNER BLOCK AL KWD-030-FNS-C1-N-1 (R163171420) is a high-precision aluminum ball runner block designed for linear motion applications requiring a lightweight yet robust component. This runner block is part of the FNS series, which stands for flanged width, normal length, and standard height, providing a compact and versatile solution for various linear guiding tasks. The runner block body is made of aluminum, which significantly reduces weight compared to steel versions while maintaining excellent mechanical properties. With a low preload class C and standard accuracy class N, this runner block ensures smooth motion with minimal play. It does not include a ball chain but comes with initial lubrication and preservation for reduced maintenance needs. The Dynalub roller bearing grease used in this product enhances its performance over the long term. This model features an optimized entry zone geometry and an increased number of balls to minimize variation in elastic deflection, contributing to its high travel accuracy—which can be up to six times higher due to the patented entry zone design. It is compatible with all SNS ball guide rails, allowing for limitless interchangeability within each accuracy class. The B.RUNNER BLOCK AL KWD-030-FNS-C1-N-1 has additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. Attachments can be mounted from both above and below the runner block, offering flexibility in design integration. The product also supports minimum quantity lubrication with an integrated reservoir for oil lubrication. This runner block is suitable for applications that benefit from a lightweight design and require compensation for low tolerances in connected structures. Its overall length measures . mm, ensuring it fits within various installation spaces without compromising on performance or precision.
