The Bosch Rexroth MINI R.BLOCK NRII MWA-015-BLS-C0-H-3 (R044159301) is a miniature ball runner block designed for precise linear motion applications. This model boasts a high accuracy class H, ensuring highly accurate movement and positioning. It has a preload class C, which means it operates without preload clearance, contributing to its smooth motion profile. The MINI R.BLOCK NRII is manufactured with corrosion-resistant steel, making it durable and suitable for various environments. With dimensions tailored for compact applications, the runner block body has a standard height and is wide and long in the BLS format. The overall length of the runner block is . mm, allowing for integration into space-constrained designs. It features an integrated lube nipple and comes with initial lubrication, although it does not include preservation or attachment elements on either front reference edge. The product's dynamic load capacity C and static load capacity C are calculated according to DIN standards. It can handle maximum acceleration amax and operates within an ambient temperature range of -20°C to +80°C, with short-term admissibility up to 100°C. The low-friction seal mini design ensures reduced resistance during operation. This model does not come with a ball chain but features ball retention capabilities that facilitate easy replacement when necessary. Furthermore, it allows for interchangeability with guide rails of every accuracy class (P, H, N), enhancing its versatility in application. Its static torsional moment load capacity Mt signifies its robustness against twisting forces. Designed primarily for miniature size E profiled rail systems, this runner block also fits size A profiled rail systems perfectly due to its self-aligning capability that compensates for misalignments without requiring self-alignment mechanisms. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-015-BLS-C0-H-3 (R044159301) offers precision movement in compact spaces while maintaining durability and versatility across different environmental conditions and rail system sizes.

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”.
