The Bosch Rexroth B.RUNNER BLOCK AL KWD-020-SNS-C0-H-1 (R163289320) is a high-precision aluminum ball runner block designed for applications that require lightweight design and the ability to compensate for low tolerances in connected structures. This runner block is part of Bosch Rexroth's linear guide system, which provides smooth and accurate linear motion in various mechanical and automation processes. The B.RUNNER BLOCK AL features an SNS format, indicating a slimline width, normal length, and standard height. Its aluminum construction significantly reduces weight without sacrificing precision, making it ideal for scenarios where mass is a critical factor. The block operates with high accuracy (class H) and comes preload-free (class C), ensuring minimal starting friction and smooth operation. This model does not include a ball chain but does come with initial lubrication and preservation to extend its service life. It also boasts an optimized entry zone geometry combined with a high number of balls to minimize variations in elastic deflection. The product's design enables excellent dynamic characteristics, including the ability to handle high accelerations while maintaining stability. Additionally, the B.RUNNER BLOCK AL has predesigned holes for pinned fitting, allowing greater parallelism and height offsets of mounting bases. It offers long-term lubrication capabilities over several years due to its integrated reservoir for oil lubrication. The runner block can be used interchangeably with all SNS ball guide rails within each accuracy class, providing flexibility in system design. Key features such as minimum quantity lubrication, excellent dynamic load capacity, and compatibility with various seals (standard seal SS, low-friction seal LS, double-lip seal DS) make this runner block suitable for diverse industrial applications. Its robustness is further enhanced by its ability to operate within a permissible ambient temperature range of -10°C to +100°C and handle significant dynamic load capacities as defined by DIN ISO standards.
