The Bosch Rexroth MINI R.BLOCK NRII (R044189301) is a high-precision miniature ball runner block designed for smooth and quiet linear motion applications. This product features a corrosion-resistant steel body in the standard BLS format, with dimensions that provide a wide width, standard height, and long length. It is characterized by its preload-free (class C) design and high accuracy (class H), ensuring precise guidance without preloading forces. The MINI R.BLOCK NRII does not include a ball chain, but it comes with initial lubrication and relubrication openings for maintenance ease. The runner block body's overall length is specified to accommodate various application requirements. A notable aspect of this product is its interchangeability with guide rails across different accuracy classes—P, H, and N—allowing for flexible system design. In terms of technical specifications, the MINI R.BLOCK NRII can withstand dynamic load capacities and torsional moment load capacities as calculated according to DIN standards. Its static load rating further emphasizes its robustness in stationary applications. The runner block can operate within an ambient temperature range from minimum permissible temperatures to a maximum that is admissible for short periods. Bosch Rexroth has engineered this runner block without self-alignment features but ensures that it can compensate for misalignments within the system. The product also includes a low-friction seal designed specifically for mini-sized profiled rail systems. As for movement capabilities, the MINI R.BLOCK NRII supports maximum permissible speeds and accelerations suitable for various dynamic applications. Overall, the Bosch Rexroth MINI R.BLOCK NRII offers reliable performance in compact spaces where high accuracy and durability are required without the need for preloading forces. Its comprehensive features make it an ideal choice for sophisticated linear motion systems demanding precision and longevity.
