The Bosch Rexroth MINI R.BLOCK NRII (R044329441) is a miniature ball runner block designed for precision linear motion applications. It belongs to the BNS format, which is characterized by a wide width, normal length, and standard height. The runner block body is constructed from corrosion-resistant steel, ensuring durability and long-term performance in various environments. With an accuracy class N indicating standard precision and a preload class C signifying that it is preload-free, this model ensures smooth operation without any initial tension. The MINI R.BLOCK NRII does not come with a ball chain or initial lubrication and lacks preservation measures, allowing users to customize these aspects according to their specific application needs. Additionally, it does not include attachment elements on either the left or right front reference edges but does feature relubrication openings for maintenance ease. This model has an overall length of . mm and supports easy interchangeability with guide rails across different accuracy classes (P, H, and N). The design optimizes ball return and guideway interaction for quiet running while also incorporating ball retention for straightforward replacement. It can handle dynamic load capacities as calculated according to DIN standards. The MINI R.BLOCK NRII operates within an ambient temperature range of -20°C to +80°C and boasts impressive load capacities: static load rating C0 and dynamic torsional moment load capacity Mt. Its maximum permissible linear speed reaches up to 5 m/s under certain conditions; however, this speed may limit service life due to increased wear on plastic components. This product is part of the Size A profiled rail systems with a BNS format width that's wide, normal length, and standard height. It's self-aligning to compensate for misalignments but does not inherently include self-alignment features. In summary, the Bosch Rexroth MINI R.BLOCK NRII (R044329441) offers robustness and precision for miniature linear motion systems with its corrosion-resistant construction and flexible integration options. It caters to applications requiring high reliability without preload interference while accommodating user-defined lubrication strategies.
