| Oil-bearing materials are porous metals and porous plastic categories. Oil-bearing porous metal, according to the matrix material divided into iron-based and copper-based. The former high carrying capacity, but prone to glue and steel shaft; the latter permissible speed is higher, but more expensive. Oil-bearing porous plastic used is a thermosetting plastic, such as nylon, phenol resin or the like. Oil-bearing porous plastic surface is very soft, easy to damage the journal, allows a greater concentricity tolerance, but the strength and stiffness lower than the oil-bearing porous metal, small carrying capacity, thermal stability and poor thermal conductivity. In order to improve this shortcoming porous plastics, plastic layer thickness can be thinned as much as possible, with a metal backing to support the plastic layer.
