The Bosch Rexroth B.RUNNER BLOCK AL KWD-020-FNS-C1-H-1 (R163181320) is a high-precision aluminum ball runner block designed for linear motion applications requiring reduced weight without compromising accuracy. This model comes from the esteemed family of Bosch Rexroth's linear motion technology and is notable for its lightweight design, thanks to its aluminum construction which significantly lowers the mass compared to steel alternatives. The B.RUNNER BLOCK AL features an FNS format that includes a width flange, normal length, and standard height. Its body is crafted from aluminum, ensuring a blend of strength and lightness. The runner block has been engineered with a low preload (Preload class C) and high accuracy class H, which makes it suitable for applications where precise motion control is critical. It does not include a ball chain but comes with initial lubrication and preservation to facilitate immediate use upon installation. With an overall length of . mm, this runner block boasts optimized entry zone geometry and an increased number of balls to minimize variations in elastic deflection. Its compact design enables it to be used effectively in lightweight constructions while compensating for low tolerances in connected structures. A patented entry zone significantly enhances travel accuracy by up to six times. This product can be paired with all SNS ball guide rails and features a lube connection with metal thread on all sides for maintenance ease. It offers improved rigidity under liftoff and side loading conditions due to two additional mounting screw holes at the center of the block. Attachments can be mounted from both above and below, providing versatility in design integration. Furthermore, the B.RUNNER BLOCK AL is prelubricated at the factory and supports minimum quantity lubrication with an integrated reservoir for oil lubrication. It has predrilled holes for pinned fitting which ensures greater parallelism and height offsets of mounting bases. The smooth operation is guaranteed by a well-designed ball return system coupled with guideway precision. In terms of technical specifications, it can withstand a maximum permissible torsional moment (Mt max), operate within ambient temperatures ranging from min ... max °C, handle dynamic loads effectively (Dynamic load capacity C), and maintain performance over several years due to long-term lubrication capabilities. This product exemplifies Bosch Rexroth's commitment to providing efficient solutions for advanced linear motion requirements across various applications.
