The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C3-U-1 (R165143920) is a ball runner block designed for ultra precision and high rigidity applications. This component is part of the linear motion technology product range, specifically engineered for dynamic and high-load situations. It features a size FNS format, which indicates a standard height, normal length, and flange width design. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength. This model boasts a high preload class C and an ultra precision accuracy class UP, making it suitable for tasks that demand the utmost precision. It does not include a ball chain but comes with initial lubrication and preservation to ensure smooth operation from the start. The Bosch Rexroth runner block has an overall length of . mm and can be used interchangeably with guide rails across different accuracies. The product is designed to offer excellent dynamic characteristics with significantly reduced frictional oscillations even under external load conditions. Its patented entry zone contributes to enhanced travel accuracy by up to six times compared to standard models. The B.RUNNER BLOCK CS allows attachments to be mounted from both above and below, offering flexibility in system design. Additionally, it features an all-around sealing system for protection against contaminants, high torque load capacity for demanding applications, and various preload classes to match specific requirements. Its design also includes additional screw holes at the center for improved side loading conditions, contributing to overall system rigidity. This runner block is pre-lubricated at the factory for convenience and supports long-term lubrication over several years. It's compatible with all SN/SNO ball guide rails by Bosch Rexroth and maintains consistent load ratings in all four main directions of loading. The product's robust design makes it suitable for applications where only one runner block per rail is necessary while still achieving maximum rigidity and performance.
