1. Strong ability to withstand heavy loads and impact loads: The rollers of NJ cylindrical roller bearings are in line contact with the raceway, which makes them have a large radial bearing capacity and suitable for withstanding heavy loads and impact loads
2. Suitable for high-speed rotation: Due to its low friction coefficient, NJ cylindrical roller bearings are suitable for use in high-speed environments, and their maximum speed is close to that of deep groove ball bearings
3. Axial movement capability: The inner or outer ring of NJ type bearings can move axially and can adapt to changes in the relative position between the shaft and the housing caused by thermal expansion or installation errors. It is suitable for use as a free end support
4. High processing requirements: The processing requirements for the shaft or seat hole are high, and the relative deviation of the outer ring axis after bearing installation should be strictly controlled to avoid contact stress concentration
5. Structural features: The inner or outer ring of the NJ type bearing can be separated, making it easy to install and disassemble. The NJ type bearing can withstand a certain degree of axial load in one direction
