The Bosch Rexroth MINI R.BLOCK NRII MWA-015-SLS-C1-H-3 (R044451301) is a high-precision miniature ball runner block designed for linear motion applications where space is at a premium and corrosion resistance is required. This model features a slimline, long, standard height (SLS) format with an overall length of the runner block being . mm. The runner block body is crafted from corrosion-inert steel, ensuring durability and longevity even in challenging environments. With a low preload class C and high accuracy class H, this product offers smooth and quiet operation, thanks to its optimally designed ball return and guideway. The absence of a ball chain contributes to this streamlined performance. Initial lubrication is provided although the product comes without preservation measures. It has an integrated lube nipple for easy maintenance and relubrication, enhancing the service life of the system. The dynamic load capacity C and static load rating C0 are calculated according to DIN standards, part 1, ensuring reliable performance under varying load conditions. The MINI R.BLOCK NRII can withstand maximum accelerations amax and operates within a permissible ambient temperature range of -20°C to 80°C. This model does not include attachment elements on either front reference edge, allowing for versatile installation options. It also features a relubrication hole for added convenience during maintenance cycles. The Bosch Rexroth miniature ball runner block is compatible with size E profiled rail systems and can be interchanged with guide rails of every accuracy class (P, H, N), providing flexibility in design and replacement. Its compact size does not compromise on capability; it can handle static torsional moment load capacities Mt as well as dynamic torsional moment load capacities Mt that are derived from its dynamic load capacity C. This product's robust design also allows it to compensate for misalignments without self-alignment features. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-015-SLS-C1-H-3 (R044451301) offers precision movement in compact spaces with its slimline design while maintaining high levels of accuracy and reliability suitable for various industrial applications requiring miniature linear motion solutions.

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”.
