The Bosch Rexroth MINI R.BLOCK NRII (R044229440) is a high-precision miniature ball runner block designed for smooth and quiet linear motion in various applications. This product is part of the company's profiled rail systems and stands out due to its slimline SNS format, which offers a width that is compact, with a normal length and standard height. The runner block body is crafted from corrosion-resistant steel, ensuring durability and longevity even in challenging environments. With an overall length of . mm, the MINI R.BLOCK NRII boasts features such as relubrication openings to facilitate maintenance and extend service life. It operates without a ball chain, initial lubrication, or preservation, allowing for immediate use in systems that may have their lubrication preferences or requirements. Additionally, this model comes preload-free (preload class C), with a standard accuracy class N. This runner block's design allows for interchangeability with guide rails across various accuracy classes (P, H, and N), providing flexibility for different precision requirements. The product also has self-aligning capabilities to compensate for any misalignments during installation or operation. Despite its miniature size, it has impressive load capacities: dynamic load capacity C and static load capacity C0 are calculated values according to DIN standards. The MINI R.BLOCK NRII is equipped with low-friction seals tailored specifically for mini-size components and does not include longitudinal seals. Its permissible ambient temperature range extends from min ... max °C, accommodating a wide range of operating conditions. The static torsional moment load capacity Mt further underscores its robustness. This runner block suits applications requiring high-speed capabilities (up to v_max) while maintaining efficiency and reliability. It's particularly well-suited for tasks where space is at a premium but performance cannot be compromised. With a weight of . kg and nominal size specifications tailored to size H profiled rail systems, the Bosch Rexroth MINI R.BLOCK NRII (R044229440) represents an optimal solution for precise linear movements in compact spaces.
