The Bosch Rexroth B.RUNNER BLOCK AL (R163219421) is a high-precision aluminum ball runner block designed for use in lightweight design applications where low tolerances with connected structures are essential. This runner block belongs to the SNS size format, which stands for slimline width, normal length, and standard height. It is constructed from aluminum, offering reduced weight without compromising on precision or dynamic characteristics. This model comes preload-free (preload class C) and offers standard accuracy (accuracy class N). It does not include a ball chain but comes with initial lubrication and preservation to ensure smooth operation right from the start. The B.RUNNER BLOCK AL features roller bearing grease Dynalub and has predrilled holes for pinned fitting, which allows for greater parallelism and height offsets of mounting bases. The product's optimized entry zone geometry coupled with a high number of balls minimizes variation in elastic deflection. Its patented entry zone increases travel accuracy up to six times compared to other systems. The runner block body is in the standard version with an overall length specified by the manufacturer. Designed for maximum precision, this ball runner block has excellent dynamic characteristics and supports minimum quantity lubrication with an integrated reservoir for oil lubrication. It boasts limitless interchangeability within each accuracy class, meaning it can be combined with all SNS ball guide rails. Long-term lubrication over several years is possible due to its robust design. The Bosch Rexroth B.RUNNER BLOCK AL is also self-aligning to compensate for misalignments and can achieve maximum permissible linear speeds (vmax). Sealing options include low-friction seals (LS) designed to prevent ingress of contaminants while ensuring ease of movement. In summary, the Bosch Rexroth B.RUNNER BLOCK AL offers an extracompact lightweight design ideal for various industrial applications that demand high precision and dynamic load capacity while maintaining a reduced weight profile compared to steel alternatives.
