The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C1-U-2 (R165151910) is a high-precision ball runner block designed for demanding linear motion applications. This component is part of the Ball Rail Systems product line and features a runner block body made of carbon steel CS, delivering durability and strength. It comes in size 55 with a format FNS, which indicates its flange width, normal length, and standard height. The runner block is characterized by an ultra precision (UP) accuracy class and a low preload (class C), ensuring smooth motion with minimal play. This model does not include a ball chain and is preserved without initial lubrication, providing flexibility for users to apply their preferred lubrication strategy. It features angular lube nipples loosely attached for easy maintenance. The B.RUNNER BLOCK CS KWC-055-FNS-C1-U-2 has been designed to offer maximum rigidity in all load directions, making it suitable for heavy-duty machine construction with high load-bearing capacity. Its innovative channel design allows for minimum lubrication quantities while ensuring smooth and quiet operation. The runner block can accommodate high torque loads and includes additional mounting screw holes at the center to improve rigidity under lift-off and side loading conditions. Attachments can be mounted from both above and below the block, enhancing versatility in various installations. Its compatibility with all SNS Ball Guide Rails means it offers limitless interchangeability across different guide rail versions. Overall, this Bosch Rexroth ball runner block is engineered to meet the requirements of applications where precision movement under heavy loads is critical. It's optimized for dynamic performance with features that address friction reduction, sealing against contaminants, and ease of servicing—making it an essential component for sophisticated linear motion systems.
