The Bosch Rexroth MINI R.BLOCK NRII MWA-015-BNS-C1-H-3 (R044351301) is a high-precision miniature ball runner block designed for linear motion applications requiring compactness and corrosion resistance. This model, part of the Miniature Ball Rail System, boasts a size BNS format with a wide width, normal length, and standard height. It is made from corrosion-inert steel to ensure durability in challenging environments. The runner block body comes with an integrated lube nipple and is preloaded to class C for low preload, ensuring smooth movement with minimal play. The high accuracy class H guarantees precise positioning and movement control. It does not include a ball chain but does come with initial lubrication and without preservation. With a dynamic load capacity calculated according to DIN 636, part 2 standards, this runner block supports high performance in various applications. Its design enables smooth and quiet running due to an optimally designed ball return system and guideway. The product also features ball retention for straightforward replacement when necessary. The overall length of the runner block is specified as . mm, while the height of the runner block when paired with its guide rail is detailed within the product specifications. This model can handle a maximum permissible linear speed of up to 5 m/s although service life may be limited due to heightened wear on plastic parts under such conditions. Designed for profiled rail systems sizes A through S including M and T min profiles, this model offers versatility in its use across different system sizes. The static and dynamic load capacities are rigorously calculated for reliability in application. For maintenance purposes, there's an available relubrication hole which simplifies upkeep procedures. It's important to note that this product has been engineered without self-alignment features but can compensate for misalignments within certain limits. The MINI R.BLOCK NRII MWA-015-BNS-C1-H-3 (R044351301) by Bosch Rexroth provides reliable performance in precision applications where space constraints and environmental resistance are critical factors.

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”.
