Cylindrical roller bearing characteristics and uses

Cylindrical roller bearing features:

1. Cylindrical roller and raceway are in line contact or repair line contact, and have large radial load capacity, suitable for heavy load and impact load.

2. N-type and NU-type can move axially, can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, and can be used for free end support.

3. The machining requirements for components such as shafts or seat holes are high. After the bearing is installed, the outer ring axis is relatively skewed, and strict control is required to avoid contact stress concentration.

4. The friction coefficient is small, suitable for high-speed rotation, and the limit speed is close to the deep groove ball bearing.

5. Cylindrical roller bearings are separate bearings. The inner or outer ring can be separated for easy installation and disassembly.

Cylindrical roller bearings are mainly used in large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery.
