The Bosch Rexroth MINI R.BLOCK NRII (R044221341) is a high-precision miniature ball runner block designed for smooth, quiet linear motion in compact applications. This model is part of the company's Miniature Ball Rail System and offers a slimline width, normal length, and standard height (SNS format), making it suitable for tight spaces where precision movement is essential. The runner block body is constructed from corrosion-resistant steel, ensuring durability and long-term performance in various environments. With a low preload class C and high accuracy class H, the MINI R.BLOCK NRII is engineered to deliver precise movements with minimal play. It does not include a ball chain or initial lubrication, which allows for customization based on the specific lubrication needs of the application. The runner block also features relubrication openings for maintenance ease. The overall length of the runner block is specified as . mm, and it boasts interchangeability with guide rails across different accuracy classes (P, H, and N). This flexibility ensures that users can combine the runner block with various guide rails to meet their exact requirements. Additionally, the ball retention system simplifies replacement processes. Dynamic load capacity C, static load capacity C0, and torsional moment load capacities Mt are all calculated according to DIN standards. The product can handle maximum accelerations and operates within a permissible ambient temperature range of -20°C to +80°C. This model does not come with attachment elements on either front reference edge but does include a low-friction seal mini for reduced wear and extended service life. The MINI R.BLOCK NRII's compact size and precision capabilities make it an ideal choice for applications requiring highly accurate linear movements within constrained spaces.
