The Bosch Rexroth MINI R.BLOCK NRII (R044389401) is a high-precision, miniature ball runner block designed for smooth and quiet linear motion in compact applications. This MINI R.BLOCK model, part of the BNS format, boasts a width that is wide for its class, with a normal length and standard height, ensuring it meets diverse installation requirements. The runner block body is crafted from corrosion-resistant steel to ensure durability and longevity even in challenging environments. This particular model features a preload class C, indicating that it is preload-free, which can be advantageous for applications requiring minimal friction. It also falls within the standard accuracy class N, making it suitable for general purposes where high precision is important but not critical. The absence of a ball chain simplifies the design and reduces maintenance needs while still allowing for easy ball replacement due to its ball retention feature. The MINI R.BLOCK NRII comes with initial lubrication but without preservation, relying on Roller bearing grease Dynalub to maintain smooth operation over time. It comes without attachment elements on both left and right front reference edges but includes relubrication openings for easy maintenance. With an overall length of mm and compatibility across various accuracy classes (P, H, and N), this runner block can be interchangeably combined with guide rails to meet specific application demands. Its static load rating C0 and dynamic torsional moment load capacity Mt are calculated according to DIN , part , ensuring reliable performance under dynamic conditions. Notably, this model can accommodate maximum permissible linear speeds of up to m/s under certain conditions; however, life expectancy may be affected by increased wear on plastic components at such speeds. Designed primarily for low-friction seal Mini without longitudinal seal configurations, it has a nominal size M and weighs just . grams—making it an ideal choice for tight spaces where weight is a critical factor. The Bosch Rexroth MINI R.BLOCK NRII (R044389401) offers flexibility in application with its self-aligning capabilities that compensate for misalignments without needing self-alignment mechanisms. Its permissible ambient temperature range ensures reliable operation in varying environmental conditions. This miniature ball runner block stands out as an efficient solution for linear motion requirements in compact spaces across various fields of application.
