Composite material bearing and manufacturing method thereof

The invention provides a composite material bearing and a manufacturing method of the composite material bearing. The manufacturing method of the composite material bearing comprises the following steps of: A, processing a steel base body to enable the surface roughness of the steel base body to achieve within Ra 1.6; B, uniformly arranging spherical copper powder on the surface of the steel base body, sintering under reducibility or inert atmosphere, and forming a multi-hole copper powder layer; and C, die pressing polytetrafluoroethylene on the surface of the steel base body on which the multi-hole copper powder layer is formed under the temperature that the polytetrafluoroethylene is in the viscosity flow state, thus forming a polytetrafluoroethylene layer with the thickness being 0.1-1.5mm, and obtaining the composite material bearing. The thickness of the surface of the obtained composite material bearing through the manufacturing method provided by the invention is 0.1-1.5mm, the polytetrafluoroethylene layer has high manufacturing accuracy and uniform elasticity modulus under the premise of guaranteeing binding strength; and the whole performance of the composite material bearing is improved, the manufacturing cost is reduced, and the application field is expanded.
