The Bosch Rexroth MINI R.BLOCK NRII (R044389441) is a high-precision miniature ball runner block designed for linear motion applications. This model, characterized by its BNS size format, features a width that is wide, a length that is normal, and a height that is standard. It boasts a runner block body made of corrosion-resistant steel, ensuring durability and longevity even in harsh environments. The MINI R.BLOCK NRII comes preload-free with a preload class C and offers standard accuracy with an accuracy class N. This particular model does not include a ball chain, initial lubrication, preservation, or attachment elements on either the left or right front reference edges. However, it does have relubrication openings to facilitate maintenance. With an overall length of the runner block at mm and the ability to combine interchangeably with guide rails across every accuracy class (P, H, and N), this product offers versatility for different system requirements. The ball return and guideway are optimally designed for smooth and quiet operation. Additionally, the ball retention feature simplifies the replacement process. This Bosch Rexroth runner block can withstand dynamic load capacities as calculated according to DIN 628-1 standards. It also has static load capacities and torsional moment load capacities derived from these values. The permissible ambient temperature range for this model spans from min to max °C for short periods. Designed without self-alignment capabilities, it compensates for misalignments within the system. The low-friction seal ensures minimal resistance during motion. The maximum permissible linear speed vmax highlights its capability of reaching up to 5 m/s; however, at such speeds, service life may be limited due to increased wear on plastic parts. Overall, the Bosch Rexroth MINI R.BLOCK NRII (R044389441) provides reliable performance in compact spaces where precision linear movement is required without compromising on quality or durability.
