The Bosch Rexroth B.RUNNER BLOCK AL KWD-035-SNS-C0-N-1 (R163239420) is a high-precision aluminum ball runner block designed for linear motion applications requiring reduced weight without sacrificing accuracy. This model is part of the SNS size series, which denotes a slimline width, normal length, and standard height. The runner block body is constructed from aluminum, offering a lightweight solution compared to its steel counterparts. The B.RUNNER BLOCK AL features a preload class C, indicating it is preload-free, and an accuracy class N for standard precision. It does not include a ball chain but comes with initial lubrication and preservation for immediate use. The product has roller bearing grease Dynalub applied and allows for attachments to be mounted from above. It boasts an optimized entry zone geometry and an increased number of balls to minimize variations in elastic deflection, making it suitable for lightweight designs and applications where low tolerances with connected structures need to be compensated. The patented entry zone significantly improves travel accuracy by up to six times. Notably, this runner block is interchangeable with all SNS ball guide rails within each accuracy class, providing excellent dynamic characteristics and the flexibility to combine various rail systems. It includes a lube connection with metal threads on all sides for easy maintenance. For mounting purposes, the runner block has pre-drilled holes that enable pinned fitting, ensuring greater parallelism and height offsets of mounting bases. Long-term lubrication over several years is possible due to the design's provision for minimum quantity lubrication with an integrated oil reservoir. In summary, the Bosch Rexroth B.RUNNER BLOCK AL KWD-035-SNS-C0-N-1 (R163239420) offers maximum precision in a compact and lightweight aluminum design suitable for various industrial applications where interchangeability and dynamic performance are critical.
