The Bosch Rexroth MINI R.BLOCK NRII (R044229441) is a miniature ball runner block designed for precision linear movement in a variety of applications. This model, part of the Miniature Ball Rail System, boasts a slimline width, normal length, and standard height (SNS format), making it suitable for compact installations where space is at a premium. The runner block body is crafted from corrosion-resistant steel to ensure durability and longevity even in challenging environments. With an accuracy class of N (standard) and preload class C (preload-free), the MINI R.BLOCK NRII ensures smooth operation without any initial tension, which can be ideal for delicate or precise movements. It lacks a ball chain, preservation, initial lubrication, and attachment elements on both left and right front reference edges but includes relubrication openings for maintenance ease. This runner block can be interchanged with guide rails of every accuracy class (P, H, and N), allowing flexibility in system design or replacement. The product is capable of handling dynamic load capacities and static load ratings as calculated according to DIN standards. Additionally, it has been engineered to provide low-friction sealing without longitudinal seals. The MINI R.BLOCK NRII's design incorporates features such as ball retention for straightforward replacement and an optimally designed ball return for smooth and quiet running. It operates within a permissible ambient temperature range from -10°C to +100°C but can withstand up to 120°C for short periods. Its low weight adds minimal mass to systems ensuring that maximum permissible speeds of up to 5 m/s are achievable with preloaded systems while maintaining service life by mitigating wear on plastic components. In summary, the Bosch Rexroth MINI R.BLOCK NRII is a high-quality miniature ball runner block that offers reliability and precision for linear motion applications requiring corrosion resistance and interchangeability with various accuracy classes without the need for preload or initial lubrication.
