The roller bearings are composed of four basic elements: rolling element (needle or roller), inner ring, outer ring, and cage. The roller bearing’s main function is to support and guide the movable machinery. When the machinery and equipment revolve, it can reduce friction, and noise and work more efficiently. But the speed of roller bearing is much slower than ball bearings. If the machine speed is high, we will recommend choosing wheel bearings.
Now, we will introduce rollers bearing from three blocks:
Material of carrier bearing: GCR15 is high-quality steel, and the hardness of the steel is HRC58-HRC65.
Inner ring and Outer ring: After special heat treatment, the service life of the ball bushing is three years.
Cage: steel cage, brass cage, and nylon cage.
