The Bosch Rexroth B.RUNNER BLOCK AL (R163281320) is a high-precision aluminum ball runner block designed for linear motion applications requiring reduced weight and high accuracy. This runner block belongs to the SNS size category, which stands for slimline width, normal length, and standard height. It features a low preload (Preload class C) and is classified under the high accuracy class (Accuracy class H). Notably, this model does not include a ball chain. The B.RUNNER BLOCK AL is pre-lubricated with Dynalub roller bearing grease to ensure smooth operation from the outset and is preserved for longevity. It has been engineered without attachment elements on both left and right front reference edges, offering flexibility in installation. The straight lube connection is loosely attached to facilitate easy maintenance. This runner block boasts an optimized entry zone geometry coupled with a high number of balls to minimize variation in elastic deflection, making it ideal for lightweight designs that need to compensate for low tolerances in connected structures. Its patented entry zone significantly increases travel accuracy by up to six times compared to standard blocks. Designed for interchangeability, this runner block can be combined with any guide rails within its accuracy class, allowing for versatile use across various applications. The ball runner block's dynamic characteristics are exceptional due to its extracompact lightweight design and the potential for long-term lubrication spanning several years. In terms of technical specifications, the B.RUNNER BLOCK AL can handle maximum permissible torsional moments (Mt max) and operates within an ambient temperature range specified in the product details. Additionally, it comes equipped with predrilled holes for pinned fitting which enables greater parallelism and height offsets of mounting bases. Overall, the Bosch Rexroth B.RUNNER BLOCK AL (R163281320) offers a combination of lightweight design, maximum precision, excellent dynamic characteristics, and long-term lubrication capabilities suitable for various industrial applications where weight reduction without sacrificing performance is crucial.
