The Bosch Rexroth B.RUNNER BLOCK AL KWD-015-FNS-C1-N-2 (R163111424) is a high-performance ball runner block designed for linear motion applications. This product is a key component of Bosch Rexroth's Ball Rail Systems and is crafted to provide smooth, quiet operation with minimal friction. Featuring an advanced design with four rows of balls, it ensures point contact in all loading directions, significantly reducing friction and heat generation compared to other systems. The B.RUNNER BLOCK AL KWD-015-FNS-C1-N-2 is manufactured according to DIN specifications, ensuring quality and compatibility with a selection of linear guides. Its ball chain and seals are engineered for durability, preventing contaminants such as dirt, chips, and coolants from affecting the block's performance and service life. The standard seal SS offers low friction with effective sealing, while the low-friction seal LS caters to applications requiring ease of movement. For environments exposed to more media, the double-lip seal DS or FKM seal provides additional protection. This model also features interchangeable front seals for environments with fine dirt or metal particles and cover plate wipers suitable for coarse dirt or chips—these accessories can be mounted by the customer during servicing. The aluminum construction of the ball runner block makes it lightweight yet capable of handling very high loads from all directions. Designed specifically for industrial robots and general machine building, it allows easy attachment from both above and below. The B.RUNNER BLOCK AL KWD-015-FNS-C1-N-2 boasts improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at its center. It offers limitless interchangeability within each accuracy class across all Ball Rail Systems. The product comes prelubricated from the factory with a minimum quantity lubrication system featuring an integrated reservoir for oil lubrication. It also has predrilled holes for pinned fitting that enable greater parallelism and height offsets when mounting. With long-term lubrication capabilities extending over several years, this ball runner block is available in accuracy classes H and N, which are combinable with all rails within each class.
