The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-H-1 (R163121322) is a high-precision aluminum ball runner block designed for use in a variety of industrial applications. It features an FNS size format, which indicates a flange width, normal length, and standard height. The runner block body is constructed from lightweight aluminum, offering reduced weight without compromising on durability. It has a low preload class C and boasts a high accuracy class H. Equipped with a ball chain, it ensures low noise levels and optimal travel behavior. This runner block is pre-lubricated with roller bearing grease Dynalub for immediate use and long-term maintenance convenience. It does not come with attachment elements on the left or right front reference edges but has straight lube connections that are loosely attached. The overall length of the runner block is standardized for interchangeability with guide rails across various accuracy classes. The B.RUNNER BLOCK AL KWD-025-FNS-C1-H-1 is particularly suitable for lightweight designs and can compensate for low tolerances in connected structures. Its optimized entry zone geometry and high number of balls reduce elastic deflection variations, while its compact design significantly lessens gravity impact compared to steel blocks. This model is capable of handling high torque loads and offers improved rigidity under liftoff and side loading conditions due to additional mounting screw holes. Attachments can be mounted from both above and below the runner block, which also features predrilled holes for pinned fittings to enhance parallelism and height offsets of mounting bases. The product supports long-term lubrication over several years, ensuring reliable operation in demanding environments. Its dynamic load capacity C, torsional moment load capacity Mt max, maximum permissible longitudinal load moment ML max, friction coefficient range, pitch T guide rail dimensions, maximum acceleration amax, preload force specifications, maximum permissible linear speed vmax, seal types (SS - Standard seal), product group ID information are detailed within its technical specifications to facilitate proper selection according to application requirements.
