The Bosch Rexroth MINI R.BLOCK NRII (R044329400) is a high-precision, miniature ball runner block designed for smooth and quiet operation in linear motion applications. This model features a size 12 format BNS, providing a wide width, normal length, and standard height for versatile use in various systems. The runner block body is constructed from corrosion-inert steel, ensuring durability and resistance to harsh environments. With a preload class C, this runner block is free from preload, making it suitable for applications where minimal friction is required. It boasts an accuracy class N (standard), which allows for interchangeability with guide rails of every accuracy within classes P, H, and N. Notably, the MINI R.BLOCK NRII does not include a ball chain but comes with initial lubrication while omitting preservation measures. The overall length of the runner block is specified at . mm. It has relubrication openings for maintenance purposes and features an uncomplicated ball return system that enhances its smooth operation. The dynamic load capacity of the unit follows DIN standards part 1 with a static load rating C and dynamic torsional moment load capacity Mt also derived from these standards. This model can withstand maximum permissible linear speeds of up to 5 m/s; however, such speeds may limit service life due to increased wear on plastic components. It has been designed to be self-aligning to compensate for any misalignments without the need for self-alignment capabilities. The Bosch Rexroth MINI R.BLOCK NRII is capable of operating within an ambient temperature range of -10°C to +100°C and can briefly endure extremes outside this range. Its compact size and robust construction make it an ideal choice for small-scale linear motion systems that demand high precision and reliability.
