The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-SNH-C0-H-2 (R162129374) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and accuracy. This runner block is part of the SNH series, featuring a slimline width, normal length, and high height format. It boasts a Resist CR coating on its unalloyed steel CS body, which is matte silver and hard chrome plated for enhanced durability. With an accuracy class H for high precision and a preload class C indicating it is preload-free, this product ensures smooth, precise movements without the need for initial tensioning. The absence of a ball chain contributes to its streamlined design. The runner block has been preserved but does not include initial lubrication or attachment elements on either front reference edge. It comes with a straight lube connection that is loosely attached. The overall length of the runner block measures . mm, and it can be interchangeably combined with guide rails of every accuracy level within its system. Its dynamic load capacity C and other load moments are determined according to DIN ISO standards based on a 100 km travel distance. This B.RUNNER BLOCK CR has a permissible ambient temperature range from ... to ... °C and can handle maximum acceleration up to amax m/s². It features low-friction coefficients ranging from . to . and supports maximum permissible linear speeds vmax. The product belongs to the Size B profiled rail systems with no self-alignment feature, ensuring it remains fixed in its orientation. The static load rating C0 and dynamic torsional moment load capacity Mt are indicative of its robustness in handling loads and moments during operation. Lastly, this model has an internal product weight of . kg with nominal size specifications tailored for precise applications in various fields requiring high-accuracy linear guidance systems.
