The Bosch Rexroth MINI R.BLOCK NRII (R044289401) is a high-precision miniature ball runner block designed for seamless motion and reliable performance in linear motion applications. This model, part of the Miniature Ball Rail System, boasts a slimline width, normal length, and standard height (Format SNS), crafted from corrosion-resistant steel to ensure durability and longevity even in challenging environments. The runner block body is preload-free (Preload class C) and adheres to standard accuracy (Accuracy class N), ensuring it meets precise operational standards without any initial tension. It does not come with a ball chain but includes relubrication openings for maintenance ease, enhancing the product's lifespan through proper lubrication practices. It comes with an initial lubrication applied but without preservation. With its overall length being specified by Bosch Rexroth standards, this model ensures interchangeability with various guide rails across different accuracy classes (P, H, and N), providing flexibility in application design. The design also incorporates features that promote smooth and quiet operation due to the optimally designed ball return and guideway. The MINI R.BLOCK NRII is capable of handling dynamic load capacities as calculated according to DIN standards for profiled rail systems of different sizes (A, B, E, H, N, S, T). It supports a maximum permissible linear speed (vmax) under certain conditions related to pretensioned systems while offering self-aligning properties to compensate for potential misalignments during installation or operation. This runner block can operate within a wide range of ambient temperatures while maintaining static and dynamic load ratings. Its low-friction seal minimizes resistance during movement within mini-sized profiled rail systems. The product's internal components are designed for reduced wear on plastic parts at higher speeds up to 5 m/s. Overall, the Bosch Rexroth MINI R.BLOCK NRII (R044289401) is engineered for precision applications requiring compact linear motion solutions with easy maintenance and robust performance characteristics.
