The Bosch Rexroth MINI R.BLOCK NRII (R044151201) is a high-precision component designed for linear motion applications requiring compact and reliable guidance systems. This miniature ball runner block, belonging to the Miniature Ball Rail System product group, is engineered to provide smooth and quiet running due to its optimally designed ball return and guideway. It features a corrosion-resistant steel runner block body that ensures durability and longevity even in challenging environments. The MINI R.BLOCK NRII boasts an accuracy class P, indicating precision construction for applications where exact movements are critical. Additionally, it comes with a low preload class C which contributes to its smooth operation. The runner block has a standard width, length, and height as per the BLS format specifications, ensuring compatibility with size E profiled rail systems. This model does not include a ball chain but is equipped with an integrated lube nipple for simplified maintenance. It also comes with initial lubrication but without preservation, utilizing roller bearing grease Dynalub for optimal performance. The runner block’s overall length measures at . mm, providing a compact solution without compromising on capability. Interchangeability is another key feature of this product; the runner block can be combined with guide rails of every accuracy class (P, H, and N), making it versatile for various applications. It has been designed without attachment elements on both left and right front reference edges for ease of installation. In terms of load capacities, the MINI R.BLOCK NRII can handle dynamic loads as calculated according to DIN , part . Its static load capacity ensures stability under stationary forces while the static torsional moment load capacity indicates resistance against twisting forces. For applications that require high acceleration or speed, this runner block can achieve speeds up to m/s with maximum permissible linear speed vmax noted in its specifications. The product also includes features such as self-alignment capabilities to compensate for misalignments during operation. Overall, the Bosch Rexroth MINI R.BLOCK NRII provides precise linear guidance in a miniature package suited for various industrial applications where space is limited but precision cannot be compromised.

Note on dynamic load capacities and moments (see the table)
Determination of the dynamic load ratings and moments is based on a total travel of 100,000 m.
Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.
Observe friction of the different seals. See document “Technical data”.
