The Bosch Rexroth B.RUNNER BLOCK AL (R163219423) is a high-precision aluminum ball runner block designed for lightweight applications and capable of compensating for low tolerances in connected structures. It features an SNS size format, which denotes a slimline width, normal length, and standard height. The runner block body is constructed from aluminum, offering reduced weight without compromising on durability or performance. This model is preload-free with a preload class C and falls under the standard accuracy class N. It comes equipped with a ball chain to ensure smooth, quiet operation and optimal travel behavior. The inclusion of initial lubrication and preservation facilitates immediate use upon installation. The B.RUNNER BLOCK AL boasts an optimized entry zone geometry and a high number of balls to minimize variations in elastic deflection. Its extra compact design results in less gravitational impact compared to steel versions, while still delivering maximum precision. The patented entry zone enhances travel accuracy significantly. All SNS ball guide rails are compatible with this runner block, allowing for limitless interchangeability across all ball guide rail systems within each accuracy class. The dynamic characteristics are exceptional due to the minimum quantity lubrication system with an integrated oil reservoir. For ease of installation, the runner block features predrilled holes for pinned fitting, which also enables greater parallelism and height offsets of mounting bases. Long-term lubrication over several years is possible thanks to its design. Additionally, the R163219423 model includes various sealing options such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal options for environments with fine dirt or metal particles, FKM seals for extreme conditions, and cover plate wipers for coarse dirt or chips environments. These various seals protect the internal mechanism from contaminants and extend the service life of the runner block. In summary, the Bosch Rexroth B.RUNNER BLOCK AL (R163219423) stands out as an efficient solution for linear motion applications requiring a combination of lightweight design, precision performance, long-term reliability, and versatile compatibility with SNS ball guide rails.
