The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-H-1 (R163121320) is a high-precision aluminum ball runner block designed for linear motion applications requiring compact, lightweight, and highly accurate guiding systems. This model is part of Bosch Rexroth's Ball Rail Systems and is distinguished by its reduced weight due to the aluminum construction, which offers less gravity impact compared to steel versions. The runner block body features a size 25 profile with an FNS format indicating a flanged width, standard height, and normal length. The B.RUNNER BLOCK AL comes with a low preload class C and a high accuracy class H. It is not equipped with a ball chain but includes initial lubrication and preservation for immediate use. The product also boasts roller bearing grease Dynalub for smooth operation. With an optimized entry zone geometry and a high number of balls, this model minimizes variation in elastic deflection, enhancing travel accuracy significantly. It has been engineered to be interchangeable with all SNS ball guide rails within each accuracy class, ensuring limitless compatibility across different system configurations. Notably, the B.RUNNER BLOCK AL features additional mounting screw holes for improved rigidity under liftoff and side loading conditions. Attachments can be mounted from both above and below the runner block. The product also supports minimum quantity lubrication with an integrated reservoir for oil lubrication. For applications that require precise movement control, this runner block's design ensures smooth operation and long-term lubrication capabilities over several years without the need for frequent maintenance. It is prelubricated at the factory to provide reliable performance from the start. In summary, the Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-H-1 (R163121320) offers maximum precision in a compact aluminum design suitable for various industrial applications where weight reduction without compromising load capacity or accuracy is essential.
