The Bosch Rexroth B.RUNNER BLOCK AL KWD-015-SNS-C0-H-1 (R163219320) is a high-precision aluminum ball runner block designed for lightweight applications requiring precise linear movement. This model is part of the SNS series, characterized by its slim width, standard height, and normal length. The runner block body is constructed from aluminum, offering a weight advantage over steel versions without compromising on durability or performance. This specific part has an accuracy class H for high accuracy and comes preload-free (preload class C). It does not include a ball chain but does feature an initial lubrication and preservation for reduced maintenance needs. The roller bearing grease used is Dynalub, which contributes to the long-term lubrication capabilities of this component. The B.RUNNER BLOCK AL KWD-015-SNS-C0-H-1 has been engineered with optimized entry zone geometry and a high number of balls to minimize elastic deflection variation, ensuring maximum precision during operation. Its patented entry zone can increase travel accuracy up to six times compared to standard models. Designed with interchangeability in mind, this runner block can be combined with any SNS ball guide rails within each accuracy class. Dynamic characteristics are excellent due to the product's design that allows minimum quantity lubrication with an integrated reservoir for oil lubrication. The pre-drilled holes facilitate pinned fitting, enabling greater parallelism and height offsets of mounting bases. With its ability to provide long-term lubrication over several years and compatibility across different accuracy classes (H and N), this runner block is an ideal solution for various industrial applications where precise linear movement is critical. Additional technical specifications include a dynamic load capacity C based on DIN ISO standards, maximum permissible torsional moment Mt max, permissible ambient temperature ranges from minimums to maximums suitable for short durations, various sizes for profiled rail systems (E, H, B, K), friction coefficients without seal friction influence, dynamic longitudinal moment load capacity ML footnote based on DIN ISO standards as well. It also features different sealing options like SS (Standard seal) for universal use or specialized seals such as LS (Low-friction seal), DS (Double-lip seal), front seals, FKM seals, and cover plate wipers available as accessories for specific environmental conditions.
