The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-N-2 (R163121424) is a high-performance ball runner block designed specifically for use in industrial robots and general machine building. It features a lightweight aluminum construction that offers very high load capacity while maintaining a low weight, making it ideal for compact, ball-bearing mounted longitudinal guides. This model adheres to DIN standards for linear guide selection and incorporates four rows of balls with point contact, allowing for minimal friction in all loading directions. The reduced friction not only enhances the movement efficiency but also minimizes heat generation. The runner block is equipped with universal standard seals (SS) that provide both low friction and effective sealing, even on guide rails with or without cover strips. For environments requiring special ease of movement, low-friction seals (LS) are available, while double-lip seals (DS) cater to increased exposure to media. In addition, front seals are offered for environments with fine dirt or metal particles and heavy use of coolants or cutting fluids; these are interchangeable during servicing. For extreme conditions, FKM seals can be used and are also serviceable by the customer. A cover plate wiper accessory can be mounted by the customer for use in environments with coarse dirt or chips. The design includes a lube port with a metal thread on all sides for easy maintenance and prelubricated at the factory for immediate use. Improved rigidity under liftoff and side loading conditions is achieved through additional mounting screw holes at the center of the block. This Bosch Rexroth ball runner block is notable for its smooth, quiet operation due to its optimally designed ball return and guidance system. It offers limitless interchangeability within each accuracy class as it can be combined at will with all Ball Rail Systems and Ball Runner Block versions. With predrilled holes for pinned fitting, it ensures greater parallelism and height offsets of mounting bases. The B.RUNNER BLOCK AL KWD-025-FNS-C1-N-2 provides long-term lubrication over several years and comes in accuracy classes H and N which are combinable with all rails within each class.
