The Bosch Rexroth B.RUNNER BLOCK AL KWD-020-SNS-C1-N-1 (R163281422) is a high-precision aluminum ball runner block designed for linear motion applications requiring compact, lightweight, and durable components. This runner block is part of the SNS size series, featuring a slimline width, normal length, and standard height. It is constructed with an aluminum body to provide reduced weight while maintaining structural integrity and precision. The B.RUNNER BLOCK AL comes with a low preload (Preload class C) and normal accuracy (Accuracy class N), ensuring smooth movement with minimal play. It includes an integrated ball chain that facilitates quiet and smooth operation while minimizing variations in elastic deflection. The runner block also features an initial lubrication and preservation with roller bearing grease Dynalub, promoting longevity and consistent performance. Designed for ease of use, this model does not include attachment elements on either the left or right front reference edge but does have a straight lube connection that is loosely attached for convenient maintenance. The overall length of the runner block is specified in the product features. This Bosch Rexroth ball runner block boasts excellent dynamic characteristics and can handle high dynamic loads (Dynamic load capacity C). Its optimized entry zone geometry allows for increased travel accuracy by up to six times compared to other systems. It also supports minimum quantity lubrication with an integrated reservoir for oil lubrication. The B.RUNNER BLOCK AL is universally interchangeable within its accuracy class across all SNS ball guide rails, offering flexibility in design and replacement. Predrilled holes enable pinned fitting for secure mounting, while its design allows compensation for parallelism and height offsets in mounting bases. With its advanced features such as long-term lubrication capabilities over several years, various sealing options like standard seal SS, low-friction seal LS, double-lip seal DS, front seal options, FKM seals for extreme environments, and cover plate wipers for coarse dirt protection—this Bosch Rexroth ball runner block meets the demanding requirements of industrial robots and machine building applications where precision movement is paramount.
