The Bosch Rexroth MINI R.BLOCK NRII MWA-012-SLS-C1-P-3 (R044421200) is a high-precision miniature ball runner block designed for linear motion applications requiring compact and corrosion-resistant components. This model is part of the Miniature Ball Rail System and stands out due to its slimline width, long length, and standard height format (SLS). The runner block body is made from corrosion-inert steel, ensuring durability and resistance to harsh environments. It features a low preload class C, indicating minimal pre-tensioning in the system for smooth movement with reduced rolling resistance. With an accuracy class P (Precision), this model guarantees high precision in positioning tasks. The MINI R.BLOCK NRII does not include a ball chain but comes with initial lubrication, though without preservation. The roller bearing grease Dynalub enhances the performance of the runner block by reducing friction. This model boasts an overall length of . mm and allows for easy interchangeability with guide rails across various accuracy classes (P, H, and N). It ensures smooth operation thanks to an optimally designed ball return and guideway. Additionally, the absence of attachment elements on both the left front reference edge and right front reference edge provides design flexibility. The product has relubrication openings for maintenance ease, contributing to extended service life. The permissible ambient temperature range spans from min ... max °C, accommodating a variety of operational environments. Furthermore, the dynamic load capacity C and static load capacity C are calculated according to DIN 636, part 2 standards. This runner block is self-aligning to compensate for any misalignments during installation or operation. It can withstand maximum permissible linear speeds up to vmax with certain limitations on service life due to wear on plastic parts in such conditions. Overall, this Bosch Rexroth miniature ball runner block is engineered for precision applications where space constraints demand compact yet robust linear motion solutions.
