The Bosch Rexroth MINI R.BLOCK NRII MWA-012-SLS-C1-H-3 (R044421301) is a high-precision miniature ball runner block designed for smooth, quiet running with an outstanding service life. This model is part of the Miniature Ball Rail System and stands out due to its slimline width, long length, and standard height format (SLS), tailored for compact applications where space is at a premium. The runner block body is crafted from corrosion-resistant steel, ensuring durability and reliability in various operating environments. This model boasts a low preload class (C) and a high accuracy class (H), making it suitable for applications requiring precise motion control with minimal play. It does not include a ball chain but comes with initial lubrication, though without preservation. The product features relubrication openings for maintenance ease and extends the operational lifespan of the runner block. With an overall length of . mm, the MINI R.BLOCK NRII provides dynamic load capacities and static load ratings calculated according to DIN standards. It can withstand maximum accelerations and operates within a permissible ambient temperature range of -20°C to +80°C. The product's design allows for self-alignment, compensating for potential misalignments without additional components. The dynamic torsional moment load capacity and static longitudinal moment load capacity are derived from standard calculations, ensuring reliable performance under various loads. Despite its miniature size, this model delivers robust performance with a low-friction seal incorporated into its design. The MINI R.BLOCK NRII MWA-012-SLS-C1-H-3 is interchangeable with guide rails across every accuracy class—P, H, and N—and supports speeds up to 5 m/s with considerations for plastic parts wear. Its nominal size facilitates integration into diverse setups while maintaining high levels of accuracy and efficiency in linear motion applications.
