The Bosch Rexroth B.RUNNER BLOCK SC KWD-020-FKS-C0-H-1 (R166189370) is a high-precision ball runner block designed for linear motion applications. It features a self-aligning capability that compensates for alignment errors up to a specified degree, ensuring smooth and accurate operation even in the presence of mounting inaccuracies. The runner block is coated with Resist CR, providing excellent corrosion resistance, and has a high accuracy class H for precise movements. This model is preload-free (preload class C), facilitating ease of movement without initial tension. Constructed from unalloyed steel CS with a matte-silver finish and hard chrome plating, the runner block boasts durability and longevity. It comes pre-lubricated from the factory with roller bearing grease Dynalub, promoting long-term lubrication over several years without the need for frequent maintenance. The dynamic characteristics of this runner block are outstanding due to its extracompact design, which also allows for greater parallelism and height offsets between mounting bases. This ball runner block does not include a ball chain or attachment elements on either side but features a straight lube connection that is loosely attached. Its overall length measures precisely in millimeters, ensuring compatibility with corresponding guide rails within each accuracy class. The product's design supports versatile mounting options as attachments can be installed from above or below. With its ability to endure significant dynamic load capacities and torsional moments as defined by DIN ISO norms, this Bosch Rexroth ball runner block is suitable for various industrial applications requiring low noise levels and exceptional travel behavior. Moreover, it provides limitless interchangeability across all ball guide rail systems within each accuracy class offered by Bosch Rexroth's comprehensive range of linear motion products.
