The Bosch Rexroth MINI R.BLOCK NRII MWA-012-BNS-C1-H-3 (R044321301) is a high-precision miniature ball runner block designed for smooth and quiet operation in linear motion applications. This model boasts a size that is suitable for compact installations, with a width classified as wide, length as normal, and height as standard according to the BNS format. The runner block body is crafted from corrosion-resistant steel, ensuring durability and longevity even in challenging environments. This MINI R.BLOCK offers low preload (Preload class C) and high accuracy (Accuracy class H), making it an ideal choice for applications requiring precise movement control. It comes with initial lubrication but without preservation, relying on roller bearing grease Dynalub for sustained performance. Notably, this model does not include a ball chain and attachment elements are absent on both the left and right front reference edges. The runner block features relubrication openings for maintenance ease and is designed to provide ball retention to facilitate easy replacement when necessary. It has an overall length of . mm and can be interchanged with guide rails of every accuracy class (P, H, N), enhancing its versatility. The dynamic load capacity C and static load capacity C0 are calculated according to DIN standards. With the capability to withstand maximum permissible linear speeds of up to 5 m/s, the MINI R.BLOCK is well-suited for high-speed applications although service life may be limited due to increased wear on plastic parts at such speeds. It also features a low-friction seal mini design that minimizes resistance during operation. In terms of environmental adaptability, this runner block can operate within a temperature range of -10°C to +100°C while handling dynamic torsional moment load capacities Mt effectively. Its lightweight design (. kg nominal weight) makes it easy to integrate into various systems without adding significant mass. Overall, the Bosch Rexroth MINI R.BLOCK NRII MWA-012-BNS-C1-H-3 (R044321301) offers reliable performance in precision motion tasks, making it a suitable component in miniature profiled rail systems across multiple application scenarios.
