The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C0-H-2 (R163129324) is a high-precision ball runner block designed for linear motion applications. This component is part of the Ball Rail Systems that offer exceptional load capacity and reduced weight, making it particularly suitable for industrial robots and general machine building. The design incorporates four rows of balls with point contact, allowing for low friction in all loading directions, which minimizes heat generation and ensures smooth operation. The B.RUNNER BLOCK AL is constructed to comply with DIN standards for linear guides, ensuring compatibility and interchangeability within its accuracy class. It features a robust sealing system that includes standard universal seals (SS), low-friction seals (LS), double-lip seals (DS), front seals, and FKM seals to protect against contaminants such as dirt, chips, coolants, and cutting fluids. These seals are designed to be interchangeable during servicing, enhancing the maintenance process. Additionally, the ball runner block offers increased rigidity under liftoff and side loading conditions due to its design which includes two additional mounting screw holes at the center. Attachments can be mounted from both above and below the block, providing versatility in assembly. The product also boasts limitless interchangeability across all Ball Rail Systems within each accuracy class. Pre-lubricated at the factory for immediate use, the B.RUNNER BLOCK AL also features an integrated reservoir for oil lubrication that supports minimum quantity lubrication. The ball return system is optimized for smooth and quiet running. Furthermore, predrilled holes on the block allow for pinned fitting which enables greater parallelism and height offsets of mounting bases. In terms of performance capabilities, this ball runner block can be used with all SNS Ball Guide Rails. It offers long-term lubrication possibilities spanning several years without requiring frequent maintenance. The accuracy classes H and N are combinable with all rails within each class to meet various application requirements.
