Classification and material characteristics of bearing material

Classification of bearing materials and material characteristics of bearing are: 1) Metal materials, such as bearing alloy, bronze, aluminum alloy, zinc base alloy, etc. ; 2) Porous metal materials ( Powder metallurgy materials) ； 3) Nonmetallic material. Including: bearing alloy: bearing alloy is also called the white metal, tin, lead, antimony and other metal alloy, because of its good wear resistant, high plasticity, running-in performance is good, good thermal conductivity and good resistance to adhesive and and good and oil adsorption, thus suitable for overloading, high-speed cases, the strength of the bearing alloy is small, the price is more expensive, must be casting in bronze, steel or cast iron shell and form a thin coating. Porous metal materials, porous metal is a kind of powder material, it has porous organization, if the immersion in the lubricating oil, full of lubricating oil in the pores, into the oil bearing, has self lubricating performance. The toughness of the porous metal material is small, only suitable for smooth without impact load and medium and small speed. Commonly used bearing bearing plastic: plastic with phenolic plastics, nylon, ptfe and so on, plastic bearings have larger compressive strength and abrasion resistance, oil and water lubrication, also has the self-lubricating properties, but poor thermal conductivity.
