The Bosch Rexroth MINI R.BLOCK NRII (R044381301) is a high-precision miniature ball runner block designed for smooth and quiet linear motion applications. This model, part of the BNS size category, features a wide format with normal length and standard height, ensuring compatibility with various design requirements. The runner block body is crafted from corrosion-resistant steel, ensuring durability and longevity even in challenging environments. With a low preload class C and a high accuracy class H, this MINI R.BLOCK provides precise movement control and is capable of accommodating slight misalignments due to its self-aligning properties. It operates without a ball chain, which simplifies maintenance while still allowing for easy replacement of balls if necessary. Initial lubrication is provided, although the unit does not come with preservation, relying on the user's maintenance regime. The runner block boasts relubrication openings for ease of maintenance and has an overall length that supports its dynamic functionality. It can be combined interchangeably with guide rails across accuracy classes P, H, and N to meet diverse application needs. The product also features a static load rating and dynamic torsional moment load capacity that are calculated according to DIN standards. Designed for miniature profiled rail systems across sizes M and S, this MINI R.BLOCK maintains performance within permissible ambient temperatures ranging from -10°C to +100°C. Its maximum permissible linear speed reaches up to 5 m/s under certain conditions but should be noted that higher speeds could result in increased wear on plastic components. In summary, the Bosch Rexroth MINI R.BLOCK NRII (R044381301) offers engineers and designers a compact yet robust solution for linear motion systems where precision and reliability are paramount. Its versatile design allows it to meet various application requirements while maintaining consistent performance over time.
