The Bosch Rexroth B.RUNNER BLOCK AL (R163219420) is a state-of-the-art ball runner block designed for high precision and lightweight applications. This aluminum runner block belongs to the SNS size category, which stands for slimline width, normal length, and standard height. It features an accuracy class N for standard precision and is preload-free (preload class C), indicating that there is no initial tension in the bearing system. The body of the runner block is crafted from aluminum, which not only ensures reduced weight but also contributes to its high-precision capabilities. The lack of a ball chain simplifies the design while maintaining performance. It comes with initial lubrication and preservation, utilizing Roller bearing grease Dynalub to ensure smooth operation right from the start. Designed without attachment elements on either front reference edge, it offers flexibility in installation with a straight lube connection loosely attached. The overall length of this runner block is tailored to meet specific application requirements while maintaining interchangeability with guide rails across all accuracy classes. This Bosch Rexroth ball runner block boasts optimized entry zone geometry and a high number of balls, minimizing variation in elastic deflection and ensuring maximum precision. Its patented entry zone significantly increases travel accuracy by up to six times compared to other systems. Furthermore, it's engineered for dynamic performance with excellent dynamic characteristics that support minimum quantity lubrication through an integrated oil reservoir. Suitable for applications requiring lightweight design and compensation for low tolerances in connected structures, this runner block can be combined with all SNS ball guide rails. It allows for greater parallelism and height offsets of mounting bases while offering long-term lubrication potential over several years. In summary, the Bosch Rexroth B.RUNNER BLOCK AL (R163219420) represents a premium choice for those seeking a lightweight yet highly precise linear motion solution that provides exceptional dynamic performance and interchangeability within its class.
