The Bosch Rexroth MINI R.BLOCK NRII MWA-009-BLS-C1-P-3 (R044181201) is a high-precision miniature ball runner block designed for smooth and quiet operation in linear motion applications. This model features a BLS format with a wide width, long length, and standard height. The runner block body is constructed from corrosion-resistant steel, ensuring durability and longevity even in challenging environments. This product boasts a low preload class C, which indicates that it has been designed with a small amount of preloading to reduce clearance and improve rigidity while still allowing for smooth movement. The precision accuracy class P ensures high accuracy in positioning tasks. Notably, the MINI R.BLOCK NRII does not come with a ball chain but includes relubrication openings for maintenance ease. The overall length of the runner block is specified as "long," accommodating various design requirements. It has been engineered to be interchangeable with guide rails across every accuracy class (P, H, and N), which provides flexibility for system integration. Additionally, the runner block has been optimized for ball return and guideway interaction, promoting quiet operation. Furthermore, the product can withstand dynamic load capacities calculated according to DIN standards and can handle maximum accelerations while maintaining performance within permissible ambient temperatures ranging from minimum to maximum degrees Celsius. The static and dynamic torsional moment load capacities are also derived from standardized calculations. This model does not include attachment elements on either front reference edge but is self-aligning to compensate for any potential misalignments during installation or operation. The low-friction seal mini contributes to reduced resistance and wear over time. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-009-BLS-C1-P-3 (R044181201) offers exceptional precision and versatility for miniature profiled rail systems with its robust construction and well-designed features supporting various industrial applications requiring precise linear movements.

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”.
