NUTR series needle wheel bearings are high-performance rolling bearings, mainly used to bear large radial loads while having small structural dimensions. This series of bearings combines the design of needle rollers and outer rings, providing excellent radial stiffness and load-bearing capacity, and is suitable for applications with limited space. The characteristics of the NUTR series include excellent wear resistance, low friction and high speed performance, which can effectively reduce energy loss during operation. The precision processing of its inner and outer rings ensures good fit and stable operation, and is suitable for applications in automobiles, engineering machinery, aerospace and other industries. This series also has a certain self-adjusting ability, which can adapt to the slight deflection of the shaft, extending the service life and reducing maintenance costs.
