The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C1-X-1 (R165111821) is a ball runner block designed for high precision and rigidity applications. This component is part of the Ball Rail Systems product group and is characterized by its size, steel CS construction, extra precision accuracy class XP, and low preload class C. It does not include a ball chain but comes with initial lubrication and preservation. The runner block body is made of unalloyed steel CS and designed to offer excellent dynamic characteristics with significantly reduced frictional oscillations and low friction force levels, especially under external load conditions. The patented entry zone increases travel accuracy up to six times, enhancing the system's performance in demanding applications. This model allows for attachments to be mounted from both above and below, providing flexibility in design integration. It features lube fittings with metal threads on all sides for easy maintenance and an end-face fastening thread for secure attachment of components. The integrated all-around sealing ensures protection against contaminants, contributing to the component's longevity. With its high torque load capacity across different preload classes and high rigidity in all load directions, this runner block can be used singularly per rail without compromising system stability. It also has improved rigidity under lift-off and side-loading conditions due to additional mounting screw holes at the center of the block. Rexroth’s design ensures maximum system rigidity thanks to a pre-tensioned O-arrangement. An optional integrated, inductive, wear-free measuring system can be included for precise monitoring of movement. Factory pre-lubrication indicates that this ball runner block is ready for immediate use upon installation. Compatible with all SN/SNO ball guide rails, this model promises long-term lubrication over several years without the need for frequent maintenance. It maintains high load ratings in all four main loading directions, ensuring reliable performance across various applications.
