① Press can withstand the load can be divided into the radial direction (radial) sliding bearings and thrust (axial) sliding bearing types.

② can be classified according to the type of lubricant oil lubricated bearings, grease lubricated bearings, water lubricated bearings, air bearings, solid lubricating bearings, magnetic bearings and magnetic bearing fluid class 7.

③ Press the lubricant film thickness can be divided into film and thick film lubricated bearings lubricated bearings categories.

④ Press bearing materials can be divided into bronze bearings, cast iron bearings, plastic bearings, jewel bearings, powder metallurgy bearings, self-lubricating bearings and oil bearing.

⑤ Press bush bearing structure can be divided circle, oval bearing, three oil leaves bearing, ladder bearing surface, tilting pad bearings and foil bearings.

Split into the bush and the overall structure. To improve the frictional properties of the surface of the pad, often cast in one or two surfaces having an inner diameter antifriction material, typically referred to as the bearing bush, so the pad and there are three bimetallic metal bearing pads. Bush or bearing liner is an important part sliding bearings, bearing and bearing liner material referred to as the bearing material. As the bush or in direct contact with the journal bearing liner, general journal section compares the wear, so the main failure mode is bearing wear.

Journal bearing wear and material, bearing their own materials, lubricants and lubrication directly related to select bearing materials of these factors should be considered in order to improve the life and work performance plain bearings.
