The Structure Of Rolling Bearing
- Jul 19, 2018 -

The common rolling bearings are generally made up of two rings, that is, inner ring, outer ring, rolling element and cage. Normally, the inner ring is aligned with the journal and rotates along the shaft, and the outer ring is fixed inside the bearing seat hole of the frame. When the inner and outer ring is rotated relative to the outer ring, the rolling body rolls on the raceway of the inner and outer rings, and the cage makes the rolling body evenly distributed and avoids the contact between the adjacent rolling bodies and the friction and wear.

The inner, outer ring and rolling body of the rolling bearing are usually made of special rolling bearing steel, such as GCr9, GCr15, GCr15SiMn and so on. The cage is usually made of soft materials, such as low carbon steel, or made of copper alloy and plastic.
