The Bosch Rexroth MINI R.BLOCK NRII (R044229341) is a high-precision miniature ball runner block designed for smooth, quiet linear motion in applications requiring compact and corrosion-resistant components. This model boasts an SNS size format, indicating a slimline width, normal length, and standard height, which makes it suitable for space-constrained environments. The runner block body is constructed from corrosion-inert steel to ensure longevity and resistance to harsh conditions. Featuring a preload class C, this MINI R.BLOCK NRII is preload-free, allowing for ease of movement without any initial tension. The high accuracy class H reflects its capability to maintain precise positioning and alignment under operation. Notably, this model does not include a ball chain or initial lubrication and lacks attachment elements on both the left and right front reference edges. However, it does come with relubrication openings to facilitate maintenance. The overall length of the runner block is specified as . mm, providing a compact footprint for various applications. One of the key attributes of this product is its interchangeability with guide rails of every accuracy class—P, H, and N—allowing for flexible system integration. The absence of self-alignment in this model necessitates precise alignment during installation but offers static torsional moment load capacity. This MINI R.BLOCK NRII has been engineered for optimal ball return and guidance which contributes to its smooth operation. Additionally, it has been designed with ball retention features that simplify the replacement process if needed. The product operates within a permissible ambient temperature range from min ... max °C and can handle dynamic load capacities as calculated according to DIN standards. In summary, the Bosch Rexroth MINI R.BLOCK NRII (R044229341) offers robust performance in miniature ball rail systems where space-saving design and corrosion resistance are essential requirements without compromising precision or load handling capabilities.
