The Bosch Rexroth MINI R.BLOCK NRII MWA-012-BNS-C0-H-3 (R044329301) is a high-precision miniature ball runner block designed for smooth and quiet linear motion in various applications. This model comes from the BNS format, which signifies a wide width, normal length, and standard height configuration, ensuring a compact yet robust design suitable for tight spaces. The runner block body is made of corrosion-resistant steel, which enhances its durability and lifespan in challenging environments. This MINI R.BLOCK is characterized by its high accuracy class H and its preload-free class C, making it ideal for applications that require precise movement without preload interference. It does not include a ball chain but features relubrication openings for maintenance ease. The product has an overall length of 23 mm and boasts an interchangeability feature that allows it to be combined with guide rails of every accuracy class—P, H, and N—enhancing its versatility. The dynamic load capacity C and static load capacity C0 are calculated according to DIN 636, part 1 standards. With a permissible ambient temperature range from -10°C to +100°C (short-term admissible), the MINI R.BLOCK can operate under various environmental conditions. It also has a maximum permissible linear speed of 5 m/s; however, this speed may reduce the service life due to increased wear on plastic parts. The low-friction seal mini design minimizes resistance during movement while protecting internal components from contaminants. The product has been engineered for self-aligning to compensate for misalignments during installation or operation without requiring additional self-alignment mechanisms. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-012-BNS-C0-H-3 (R044329301) offers exceptional precision and reliability for demanding linear motion tasks where space is at a premium while maintaining ease of maintenance through features like relubrication openings and ball retention for straightforward replacement.
