The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C1-X-1 (R165321820) is a state-of-the-art linear motion component designed for high-precision and demanding applications. This ball runner block is part of the Ball Rail Systems product group, offering exceptional running properties due to its four rows of balls with point contact, which reduces friction to a minimum. The FLS format indicates a flanged, long, and standard-height runner block made from unalloyed steel CS with an overall length of . mm. The R165321820 boasts an extra precision accuracy class XP and low preload class C, ensuring precise movement without excessive friction or play. Notably absent is the ball chain, emphasizing its streamlined design. It comes pre-lubricated with Roller bearing grease Dynalub for long-term maintenance-free operation and features integrated all-around sealing to protect against contaminants. This runner block can be utilized in single-block configurations per rail due to its high rigidity in all load directions, facilitated by additional mounting screw holes for enhanced stability under side loading conditions. The product also allows for versatile attachment options, with end-face fastening threads and the ability to mount attachments from both above and below the block. Compatible with all SN/SNO ball guide rails, the Bosch Rexroth B.RUNNER BLOCK CS ensures maximum system rigidity through its preloaded O-arrangement and supports optional integration of an inductive measuring system for real-time tracking of movement. It's designed to meet the most stringent rigidity requirements while maintaining low friction oscillations even under external load conditions. The product's dynamic characteristics are excellent, supporting high torque capacity across different preload classes. The R165321820 model is suitable for various environments as it can operate within a permissible ambient temperature range from min ... max °C. With its versatile design and robust construction, it serves as a reliable component in precision linear motion systems.
