The Bosch Rexroth MINI R.BLOCK NRII MWA-015-SLS-C0-H-3 (R044459301) is a high-precision miniature ball runner block designed for linear motion applications requiring a compact and corrosion-resistant solution. This runner block features a slimline width, long length, and standard height format (SLS), made from corrosion-inert steel with an overall length of . mm. It is characterized by its high accuracy class H and is preload-free, belonging to preload class C. The MINI R.BLOCK NRII comes without a ball chain, has an integrated lube nipple, and is supplied with initial lubrication but without preservation. The product's dynamic load capacity C and static load capacity C are calculated according to DIN standards. It offers smooth and quiet operation due to its optimally designed ball return and guideway, in addition to ball retention which simplifies replacement procedures. The runner block can operate in ambient temperatures ranging from min ... max °C for short periods and has a maximum permissible linear speed vmax. This model does not include attachment elements on either the left or right front reference edges, ensuring versatility in mounting options. Its self-aligning capability allows for compensation of misalignments without the need for self-alignment features. Furthermore, it boasts impressive static torsional moment load capacity Mt as well as dynamic longitudinal moment load capacity ML. Designed for use with size E, N, A, B, H, V . , S, T profiled rail systems from Bosch Rexroth's range of material profiled rail systems, this runner block ensures interchangeability across different accuracy classes P, H, and N. It also features a low-friction seal specifically tailored for miniature applications. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-015-SLS-C0-H-3 (R044459301) offers exceptional precision and flexibility for demanding linear motion tasks where space constraints are critical while ensuring durability through its corrosion-resistant construction.

2) Speeds of up to 5 m/s are possible. Service life is limited by increased wear to plastic parts.
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”.
