The Bosch Rexroth MINI R.BLOCK NRII MWA-012-SLS-C0-H-3 (R044429301) is a high-precision miniature ball runner block designed for linear motion applications requiring compact and robust guidance systems. This model, part of the Miniature ball rail system product group, offers a slimline width, long length, and standard height configuration (SLS format), ensuring a minimal footprint while providing reliable performance. The runner block body is made from corrosion-resistant steel, suitable for various environments. With a preload class C0 indicating that it is preload-free and an accuracy class H for high accuracy, this component ensures smooth operation without unnecessary pre-tensioning that could affect the system's responsiveness. It does not come with a ball chain but includes initial lubrication and relubrication openings to maintain optimal performance over time. This model boasts an overall length of 38.7 mm and can be easily combined with guide rails of every accuracy class (P, H, N), enhancing interchangeability within systems. The MINI R.BLOCK NRII has been designed without attachment elements on both left and right front reference edges for greater installation flexibility. Key features include low-friction seals for reduced resistance and increased service life, even at speeds up to 5 m/s—though higher speeds may result in increased wear on plastic parts. Its dynamic load capacity C and static load rating C0 are calculated according to DIN 636, part 2 standards. The permissible ambient temperature range for operation extends from -10°C to +100°C. Furthermore, the runner block's design allows for self-alignment to compensate for potential misalignments within the system. It also possesses considerable static and dynamic torsional moment load capacities (Mt), ensuring stability under various load conditions. This Bosch Rexroth component is suitable for applications demanding high precision in compact spaces across various sectors due to its combination of size, performance capabilities, and material quality.
