The Bosch Rexroth B.RUNNER BLOCK AL KWD-015-FNS-C0-N-1 (R163119421) is a high-precision aluminum ball runner block designed for various industrial applications requiring compact, lightweight, and robust linear motion guidance. This runner block belongs to the FNS format, which indicates a flange width, normal length, and standard height. It is constructed from aluminum, providing a lower weight alternative to steel versions while maintaining high precision. The model features an accuracy class N (standard) and comes preloaded in class C (preload-free), ensuring smooth motion without excessive preload force. It does not include a ball chain but has been initially lubricated and preserved for immediate use. The unit is equipped with roller bearing grease Dynalub for optimal performance. This ball runner block is notable for its optimized entry zone geometry and a high number of balls that minimize variations in elastic deflection. Its extra compact design significantly reduces gravity effects compared to steel variants, enhancing precision in applications where weight is critical. With its innovative design, the B.RUNNER BLOCK AL offers improved rigidity under lift-off and side loading conditions due to additional mounting screw holes at the center of the block. Attachments can be mounted from both above and below the runner block. Furthermore, it boasts limitless interchangeability within each accuracy class across all SNS ball guide rails. The product's overall length is specified in millimeters, with predrilled holes allowing for pinned fitting to achieve greater parallelism and height offsets of mounting bases. Its quiet operation stems from an optimally designed ball return system that ensures smooth movement. In summary, the Bosch Rexroth B.RUNNER BLOCK AL KWD-015-FNS-C0-N-1 (R163119421) offers maximum precision in a lightweight package suitable for various industrial applications where reduced weight and long-term reliability are paramount.
