Nu and nj bearing

The nu and nj bearing has a large load capacity and mainly bears radial loads. The rolling element has little friction with the retaining edge of the ring, making it suitable for high-speed rotation. According to the presence or absence of retaining edges on the ring, there are single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. nu and nj bearing is a separable structure with inner and outer rings.
NU and nj bearing without retaining edges on the inner or outer ring can move relative to the axial direction, making them suitable for use as free end bearings. A nu and nj bearing with double retaining edges on one side of the inner and outer rings, and a single retaining edge on the other side of the ring, which can withstand a certain degree of axial load in one direction. Generally, steel plate stamped cages or copper alloy solid cages are used.

Characteristic of nu and nj bearing:
1. The roller and raceway are in line contact or repaired line contact, with a large radial bearing capacity, suitable for nu and nj bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speeds, and the maximum speed is close to that of deep groove ball bearings.
3. NU and nj bearing type can move axially and adapt to changes in the relative position between the shaft and the casing caused by thermal expansion or installation errors.They can be used as free end supports.

4. The machining 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. The inner or outer ring can be separated for easy installation and disassembly.
