The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C0-N-1 (R163129421) is a high-precision, lightweight aluminum ball runner block designed for industrial automation and machine building applications. It features a standard-width flange, normal length, and standard height, offering a compact and robust solution for linear motion requirements. This runner block body is made from aluminum, providing not only a reduced weight compared to steel versions but also maintaining high precision. The product comes with a preload class C, indicating that it is preload-free, which is suitable for applications requiring smooth movement without additional internal force. The accuracy class N signifies that it follows standard manufacturing tolerances. Notably, this model does not include a ball chain but is equipped with initial lubrication and preservation for immediate use upon installation. With an overall length of the runner block at . mm, the B.RUNNER BLOCK AL KWD-025-FNS-C0-N-1 ensures compatibility with all SNS ball guide rails and offers interchangeability across different accuracy classes. It boasts an optimized entry zone geometry and a high number of balls to minimize variation in elastic deflection. The design includes two additional mounting screw holes at the center for improved rigidity under lift-off and side loading conditions. For maintenance convenience, the runner block supports minimum quantity lubrication through an integrated reservoir for oil lubrication and comes pre-drilled for pinned fitting to enable greater parallelism and height offsets of mounting bases. The smooth operation is guaranteed by the optimized ball return and guide way system. In terms of durability, this model allows long-term lubrication over several years without significant maintenance requirements. Its dynamic load capacity C and maximum permissible torsional moment Mt max are based on extensive testing as per DIN ISO standards, ensuring reliability in demanding operational conditions. The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C0-N-1 represents an advanced solution in linear motion technology combining lightweight design with uncompromised performance.
