The Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-SNS-C0-N-0 (R201179404) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications where space is restricted in the transverse direction. This robust component features a Resist NRII material construction, ensuring durability and resistance to corrosive environments. The ball runner block boasts size 30 dimensions with an SNS format, which indicates a slimline width, normal length, and standard height for compatibility with various installation requirements. The runner block body and all steel components are manufactured from corrosion-resistant steel compliant with DIN standards, offering longevity and consistent performance. It is characterized by a preload class C0, indicating that it is preload-free for smooth motion without excessive friction or wear. The accuracy class N ensures standard precision levels suitable for a wide range of applications. This model does not include a ball chain and comes without preservation or initial lubrication, allowing users to customize the lubrication system according to their specific needs. It also lacks attachment elements on both left and right front reference edges but includes a straight lube connection that is loosely attached. The B.RUNN. BLOCK NRII KWD-030-SNS-C0-N-0 can be used with all SNS ball guide rails from Bosch Rexroth and supports long-term lubrication over several years. Its patented entry zone significantly enhances travel accuracy up to six times compared to conventional systems while maintaining low frictional oscillations even under external load. With its optimized entry-zone geometry and high number of balls, this runner block minimizes variation in elastic deflection while delivering excellent dynamic characteristics. An integrated all-around sealing system protects against contaminants, extending the service life of the component. The overall length of the runner block is specified at 63 mm, with the ability to withstand ambient temperatures ranging from -10°C up to +100°C for short periods. It has impressive load capacities in all four main directions of loading and allows attachments to be mounted from above. This model's dynamic load capacity C and static longitudinal moment load capacity ML are determined based on a 100 km travel as per DIN ISO standards. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-SNS-C0-N-0 (R201179404) offers exceptional performance for linear motion systems requiring corrosion resistance, precision, and durability within compact spaces.
