The Bosch Rexroth B.RUNNER BLOCK AL (R163181420) is a high-precision aluminum ball runner block designed for use in industrial robots and general machine building. It offers a compact, ball bearing-mounted longitudinal guide with an exceptional load capacity while maintaining a low weight profile. The B.RUNNER BLOCK AL features an FNS format, indicating its flange width, normal length, and standard height specifications. This runner block is constructed from aluminum, providing reduced weight compared to steel versions without sacrificing precision. It comes with a low preload (Preload class C) and standard accuracy (Accuracy class N), ensuring smooth operation under normal conditions. The absence of a ball chain contributes to the unit's streamlined design. Equipped with initial lubrication and preservation, this product is ready for immediate use upon installation. The roller bearing grease Dynalub is included for optimal performance. With its straight lube connection loosely attached, the B.RUNNER BLOCK AL facilitates easy maintenance and lubrication. The overall length of the runner block is specified, allowing users to select the appropriate size for their application needs. Its optimized entry zone geometry coupled with a high number of balls ensures minimal variation in elastic deflection, enhancing travel accuracy significantly. The Bosch Rexroth B.RUNNER BLOCK AL boasts improved rigidity under liftoff and side loading conditions due to two additional mounting screw holes at its center. Attachments can be mounted from both above and below the runner block body, providing flexibility in design integration. This product's interchangeability feature allows it to be combined with any guide rails within each accuracy class, offering limitless configuration options. It supports long-term lubrication over several years and comes prelubricated from the factory for convenience. Finally, predrilled holes on the Ball Runner Block facilitate pinned fitting for increased stability and precision alignment in mounting bases. The unit's quiet operation is attributed to its well-designed ball return system and guidance track alignment.
