The Bosch Rexroth MINI R.BLOCK NRII MWA-020-SNS-C1-P-3 (R044201200) is a high-precision miniature ball runner block designed for smooth, quiet running and easy ball replacement. This model features a slimline width, standard height, and normal length format (SNS), with a runner block body made of corrosion-resistant steel. It boasts a low preload class C and precision accuracy class P, ensuring reliable performance in demanding applications. The MINI R.BLOCK NRII does not include a ball chain, but it comes with initial lubrication and is free from preservation treatments. It utilizes roller bearing grease Dynalub for sustained operation. The runner block does not have attachment elements on either the left or right front reference edges but includes an integrated lube nipple. With an overall length specified for this model, the runner block has been designed to be interchangeable with guide rails across every accuracy class—P, H, and N—offering flexibility in assembly and maintenance. It features a relubrication hole for ease of maintenance and is capable of operating within an ambient temperature range of -10°C to 100°C while maintaining its dynamic load capacity as per DIN standards. This product is self-aligning to compensate for any misalignments without the need for additional self-alignment mechanisms. Its static torsional moment load capacity Mt is calculated based on the dynamic load capacity C values. The MINI R.BLOCK NRII can achieve maximum permissible linear speeds up to 5 m/s; however, service life may be limited at these speeds due to increased wear on plastic components. Specifically designed for size A through E profiled rail systems, this miniature ball rail system ensures high reliability in linear motion tasks with its robust construction and precise engineering. The product's nominal size aligns with the size H profiled rail systems specifications, making it suitable for various industrial applications where space constraints and precision are critical factors.
