Single row cylindrical roller bearing
Single row cylindrical roller bearings are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs.
Cylindrical roller and raceway for the line contact bearings. Load capacity, the main radial load. Rolling ring wall friction is small, suitable for high-speed rotation. According to ring without ribs, can be divided NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is the inner, outer separable structure.
Inner or outer wall of the cylindrical roller bearings, the inner and outer ring can be relative to the axial movement, so you can use as a free end bearings. On either side of the inner and outer ring of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings that can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also some use of polyamide forming cage.
Features of Cylindrical Roller Beraings:
1. The roller and rollaway nest for the line contact or offline contact,it radial bearing capacity big, suitable for bear heavy loading
2. The friction coefficient is small, suitable for high speed, the limit speed is close to the deep groove ball bearings.
3. The type of N 'sand NU's axial may movement,
4. The inner ring or outer ring separable, easy to install and disassemble
