NU cylindrical roller bearings

Axial movement capability: The inner or outer ring of NU type cylindrical roller bearings has no blocking edge, so they can move relative to each other in the axial direction. This design enables the bearing to adapt to changes in the relative position between the shaft and the housing caused by thermal expansion or installation errors, and is commonly used for free end support

1. Axial movement capability: The inner or outer ring of NU type cylindrical roller bearings has no blocking edge, so they can move relative to each other in the axial direction. This design enables the bearing to adapt to changes in the relative position between the shaft and the housing caused by thermal expansion or installation errors, and is commonly used for free end support
2. Load bearing capacity: The rollers and raceways of NU type bearings are in line contact or repaired in line contact, with a large radial load capacity
Suitable for withstanding heavy loads and impact loads
3. Friction characteristics: Its friction coefficient is small, suitable for high-speed operation, and the maximum speed is close to that of deep groove ball bearings
4. Installation and disassembly: The detachable design of the inner or outer ring makes the installation and disassembly of the bearing more convenient
5. 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
