What are the characteristics and uses of roller bearings?

1: The roller and the raceway are in line contact or repaired line contact, and have a large radial load capacity, which is suitable for those subjected to heavy load and impact load.

2: The friction coefficient is small, suitable for those high speeds, and the limit speed is close to the deep groove ball bearing.

3: The N-type and NU-type can move axially, and 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 as a free end support.

4: The machining requirements for the shaft or the seat hole are relatively high, and the relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration.

5: The inner ring or the outer ring can be separated to facilitate the installation and disassembly of the bearing.

The main applications are: 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.

Ball bearings and roller bearings are both rolling bearings. The simplest one is that the rolling elements are balls, which are steel balls. The other rolling element is a steel column.
