The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-H-2 (R163121324) is a high-performance ball runner block designed for precision and durability in linear motion systems. This product is part of the Ball Rail Systems and is engineered to provide low friction movement in all loading directions due to its four rows of balls with point contact. The design significantly minimizes friction, which reduces heat generation compared to other systems that might experience up to five times the friction coefficient under similar conditions. The B.RUNNER BLOCK AL KWD-025-FNS-C1-H-2 features a selection of seals to protect against contaminants such as dirt, chips, and coolants, thus extending its service life. The standard seal SS offers a balance between low friction and effective sealing, while the low-friction seal LS caters to applications requiring smooth movement. For harsher environments with increased exposure to media, the double-lip seal DS or FKM seal can be utilized. Front seals are also available for environments with fine particles or heavy use of coolants, and cover plate wipers for coarse dirt or chips; both are interchangeable during servicing. This ball runner block boasts enhanced rigidity under liftoff and side loading conditions due to additional mounting screw holes at the center. Attachments can be mounted from both above and below, ensuring versatility in various applications. It offers limitless interchangeability within each accuracy class across all Ball Rail Systems and Ball Runner Block versions. Pre-lubricated at the factory with an integrated reservoir for oil lubrication ensures long-term maintenance-free operation, while predrilled holes allow for precise pinned fitting. The smooth running is achieved through an optimally designed ball return system, contributing to quiet operation. With accuracy classes H and N combinable with all rails within each class, this product supports high load capacities while maintaining compact dimensions suitable for industrial robots and general machine building applications where space efficiency and load capacity are critical.
