Oil-free sliding bearing varieties:
1 Sliding self-lubricating bearings in the direction of receiving load can be divided into radial (central) oil-free sliding bearings and thrust (axial) oil-free sliding bearings.
3 According to the thickness of the smooth film, it can be divided into two types: thin film smooth bearing and thick film smooth bearing.
4 According to the bearing material, it can be divided into bronze bearing, cast iron bearing, plastic bearing, jewel bearing, powder metallurgy bearing, self-smooth bearing and oil bearing.
5 According to the bearing structure can be divided into round bearing, elliptical bearing, three oil leaf bearing, step surface bearing, tilting pad bearing and foil bearing.
