The Bosch Rexroth MINI R.BLOCK NRII MWA-009-SLS-C0-N-3 (R044489401) is a high-quality miniature ball runner block designed for smooth and quiet linear motion in various applications. This product features a slimline width, long length, and standard height (SLS format), ensuring compactness and compatibility with restricted spaces. The runner block body is crafted from corrosion-resistant steel, making it suitable for environments where material integrity is paramount. With a preload class C, this runner block is preload-free, providing ease of movement without the need for initial force adjustment. The accuracy class N denotes standard precision suitable for a wide range of uses. This model does not include a ball chain but comes with initial lubrication and relubrication openings for maintenance convenience. The MINI R.BLOCK NRII boasts an overall length of . mm and can be combined with guide rails of every accuracy class (P, H, and N), allowing for versatile integration into existing systems. It has been designed to accommodate dynamic load capacities as per DIN standards and can handle maximum accelerations effectively. Notably, this miniature ball runner block operates within a permissible ambient temperature range of - C to + C and can withstand short-term variations outside this range. It also features low-friction seals that minimize resistance during operation while protecting internal components from contaminants. The product's internal design ensures optimal ball return and guidance for extended service life even at high speeds up to m/s while compensating for potential misalignments without the need for self-alignment mechanisms. Its static torsional moment load capacity further underscores its robustness in handling loads from various directions. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-009-SLS-C0-N-3 (R044489401) is an advanced solution designed to deliver reliable linear motion with minimal maintenance requirements in diverse applications requiring precise control within compact spaces.

3) Brief peaks up to 100°C are permissible.

Note on dynamic load capacities and moments (see the table)

Determination of the dynamic load ratings and moments is based on a total travel of 100,000 m.

Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.

Observe friction of the different seals. See document “Technical data”.
