The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C0-H-2 (R165129324) is a state-of-the-art ball runner block designed for high-performance linear motion applications. This component is part of the Ball Rail Systems that adhere to DIN standards, ensuring compatibility and interchangeability with various linear guides. It features a robust design with four rows of balls that establish point contact in all loading directions, significantly minimizing friction. This design choice not only reduces wear and tear but also decreases heat generation, which can be detrimental to the system's longevity. The ball runner block incorporates several seal options to protect against contaminants such as dirt, chips, and coolants, which can affect its service life. The standard seal SS offers low friction with effective sealing capabilities for both covered and uncovered guide rails. For environments requiring minimal resistance to movement, the low-friction seal LS is ideal, while the double-lip seal DS provides enhanced protection in media-rich settings. Additionally, front seals are available for environments with fine particles or heavy coolant use and can be replaced during servicing. For extreme conditions, FKM seals offer superior resistance and are also replaceable by the customer. The cover plate wiper is an accessory designed for use in environments with coarse dirt or chips. This ball runner block boasts features like attachments from above and below, metal-threaded lube fittings on all sides, end-face fastening threads for attachments, integrated all-around sealing, high torque capacity, various preload classes for different rigidity requirements, and improved rigidity under liftoff and side loading conditions due to additional mounting screw holes. Notably, this model has high load ratings in all four main directions of loading and can function optimally with just one runner block per rail. It offers maximum system rigidity thanks to its pretensioned O-arrangement and an optional integrated measuring system that's inductive and wear-free. Pre-lubricated at the factory for immediate use on all SN/SNO Ball Guide Rails, it supports long-term lubrication over several years without the need for frequent maintenance.
