The Bosch Rexroth B.RUNNER BLOCK AL (R163281420) is a high-precision aluminum ball runner block designed for linear motion in various industrial applications. This model, part of the Ball Rail Systems product group, offers a sleek and lightweight solution without compromising on strength or accuracy. It features size and format SNS, which stands for slimline width, normal length, and standard height. The runner block body is crafted from aluminum to reduce weight while maintaining robust performance. The R163281420 comes with a low preload (class C) and standard accuracy (class N), ensuring smooth movement without excessive rigidity or play. It is delivered without a ball chain but includes initial lubrication and preservation to facilitate immediate use upon installation. The roller bearing grease used is Dynalub, which provides reliable lubrication over extended periods. This model boasts an optimized entry zone geometry and a high number of balls to minimize variation in elastic deflection, making it ideal for lightweight designs that require compensation for low tolerances in connected structures. Its extracompact design results in less gravitational impact compared to steel runner blocks. With excellent dynamic characteristics and the ability to combine with all SNS ball guide rails, the B.RUNNER BLOCK AL ensures maximum precision. It includes predesigned holes for pinned fitting, allowing greater parallelism and height offsets of mounting bases. Furthermore, the ball runner block's interchangeability feature means that all ball guide rail systems can be combined at will within each accuracy class. For applications requiring long-term lubrication, this model can maintain its performance for several years due to its integrated reservoir for oil lubrication. Additionally, it can withstand a wide range of operating temperatures from minimum permissible ambient temperature to maximum permissible ambient temperature as specified in the detailed specifications. In summary, the Bosch Rexroth B.RUNNER BLOCK AL (R163281420) provides an efficient solution for those seeking a durable yet lightweight linear motion component with excellent dynamic properties and compatibility across various accuracy classes within Bosch Rexroth's Ball Rail Systems range.
