The Bosch Rexroth B.RUNNER BLOCK AL KWD-015-FNS-C1-H-1 (R163111321) is a high-precision ball runner block designed for linear motion applications where reduced weight and high accuracy are essential. This aluminum runner block boasts a low preload and belongs to the high accuracy class H, ensuring precise movements without the additional weight of steel alternatives. It's suitable for lightweight designs and can compensate for low tolerances in connected structures. The B.RUNNER BLOCK AL KWD-015-FNS-C1-H-1 is part of the Ball Rail Systems product group, characterized by its size and FNS format, indicating a flange width, normal length, and standard height. It comes without a ball chain but includes initial lubrication and preservation with roller bearing grease Dynalub. The runner block body is made of aluminum for an optimized balance between strength and mass. This model features an overall length of the runner block at . mm and offers improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at its center. Attachments can be mounted from both above and below the ball runner block, providing flexibility in design. With its patented entry zone geometry and a high number of balls, it minimizes variation in elastic deflection while ensuring maximum precision. It's compatible with all SNS ball guide rails, allowing limitless interchangeability within each accuracy class. The lube connection has metal threads on all sides for easy maintenance. The product also supports long-term lubrication over several years due to its integrated reservoir for oil lubrication. Designed with predrilled holes for pinned fitting, it enables greater parallelism and height offsets of mounting bases. Users will appreciate its smooth, quiet operation thanks to the optimally designed ball return and guidance system. Moreover, it can withstand dynamic load capacities as per DIN ISO standards with the ability to multiply values by 1.26 for comparison purposes when stipulated travels differ from standard measurements.
