The Bosch Rexroth MINI R.BLOCK NRII (R044281200) is a high-precision miniature ball runner block designed for smooth and quiet linear motion in various applications. This model boasts an accuracy class P, indicating its precision, and a low preload class C, ensuring minimal starting friction. The MINI R.BLOCK NRII does not come with a ball chain but features initial lubrication, enhancing its ready-to-use capability while lacking preservation measures. Constructed from corrosion-resistant steel, the runner block body is durable and suitable for use in environments where corrosion might be a concern. The absence of attachment elements on both the left and right front reference edges allows for more versatile installation options. Additionally, the product includes relubrication openings that facilitate maintenance and longevity of the runner block. With an overall length of mm, this model is compatible with size A, B, E, H, N, S, T profiled rail systems and can be combined with guide rails across every accuracy class (P, H, and N), allowing for flexible integration into existing systems. The design ensures easy ball replacement due to the ball retention feature and supports a maximum permissible linear speed of vmax. The dynamic load capacity C and static load rating C0 are calculated according to DIN standards. Furthermore, it can handle static torsional moment load capacities Mt as well as dynamic longitudinal moment load capacities ML. The MINI R.BLOCK NRII operates within a permissible ambient temperature range from min to max °C for short periods. This runner block is particularly suited for applications requiring precise linear guidance with space constraints due to its slimline width (SNS format), standard height, and normal length configuration. It's also self-aligning to compensate for any misalignments during operation without requiring additional adjustments.
