The Bosch Rexroth B.RUNNER BLOCK AL KWD-035-FNS-C0-N-1 (R163139420) is a high-precision aluminum ball runner block designed for linear motion applications that require reduced weight without compromising on accuracy and durability. This component is part of the Ball Rail Systems, specifically tailored for lightweight design considerations and compensating low tolerances in connected structures. The runner block features an FNS format, indicating a width with flange, normal length, and standard height dimensions. It is made from aluminum for a lighter alternative to steel versions, yet it maintains a high level of precision.
The model comes preloaded free (preload class C) and offers standard accuracy (class N), ensuring smooth movement without excessive friction or play. Notably, this runner block does not include a ball chain but does come with initial lubrication and preservation to facilitate immediate use upon installation. It also features roller bearing grease Dynalub for enhanced performance.
The design of the B.RUNNER BLOCK AL KWD-035-FNS-C0-N-1 includes optimized entry-zone geometry and a high number of balls which minimize variation in elastic deflection, contributing to its exceptional travel accuracy—a patented feature that can increase travel accuracy by up to six times. Its compact and lightweight design results in less gravitational force compared to steel blocks, further enhancing its suitability for various applications.
Furthermore, the runner block boasts improved rigidity under lift-off and side loading conditions due to additional mounting screw holes at its center. Attachments can be mounted from both above and below the block, offering flexibility in system integration. The product's interchangeability feature allows it to be combined with any SNS ball guide rails within each accuracy class.
This Bosch Rexroth runner block is prelubricated at the factory ensuring long-term lubrication over several years is possible. The product also has predesigned holes for pinned fitting which enables greater parallelism and height offsets of mounting bases. Its smooth operation is attributed to an optimally designed ball return and guideway system that ensures quiet running even under load.
