The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C1-N-2 (R165111424) is a state-of-the-art ball runner block designed for high-performance linear motion applications. It features an innovative design with four rows of balls that provide point contact in all loading directions, significantly reducing friction and minimizing heat generation compared to other ball rail systems. This design ensures high precision and smooth movement even under varying load conditions. The ball runner block is constructed according to DIN standards, ensuring compatibility and reliability across various industrial applications. It includes a ball chain and seals that protect the internal mechanisms from contaminants such as dirt, chips, and coolants, thereby extending the service life of the unit. The standard seal SS provides effective sealing with low friction for both covered and uncovered guide rails. For specialized requirements, this model offers low-friction seal LS options for ease of movement, double-lip seal DS for increased exposure to harsh media, and FKM seals for extreme environments. Additionally, front seals are available to shield against fine dirt or metal particles and can be easily interchanged during servicing. The B.RUNNER BLOCK CS also boasts attachments that can be mounted from above or below, metal-threaded lube fittings on all sides, end-face fastening threads for various attachments, integrated all-around sealing, high torque capacity, different preload classes for tailored rigidity levels, and exceptional rigidity in all load directions allowing use with just one runner block per rail. Enhanced system rigidity is achieved through pretensioned O-arrangement of balls and additional mounting screw holes at the center of the block. For applications requiring precision measurement, an optional integrated inductive measuring system is available. The unit comes pre-lubricated from the factory suitable for use on all SN/SNO Ball Guide Rails with potential long-term lubrication over several years without maintenance. This model maintains high load ratings in all four main directions of loading—a testament to its robust design tailored for demanding linear motion tasks.
