Oil Impregnated Copper Bearings Powder Metallurgy Porous Bearing Bushing

Oil-Impregnated Bearings Features

    Oil-impregnated bearings, namely porous bearings, use metal powder as the main raw material and use powder metallurgy to produce a sintered body. It is inherently porous and has the number and size of pores that can be adjusted freely during the manufacturing process. , Shape and distribution, etc. The porous nature of the material can be used to fill the pores with lubricating oil.

    Oil-impregnated bearings have the characteristics of low cost, vibration absorption, low noise, and no need to add lubricating oil during a long working time, and are especially suitable for working environments that are not easy to lubricate or do not allow oil to be dirty. Porosity is an important parameter of oil-bearing bearings. Oil-impregnated bearings working at high speeds and light loads require high oil content and high porosity; oil-impregnated bearings working at low speeds and heavy loads require high strength and low porosity.

    Oil-impregnated bearings have low manufacturing costs, easy use, excellent wear resistance, seizure resistance, and friction resistance. They can achieve high mechanical performance without maintenance. So it has been widely used, and now it has become an indispensable basic part for the development of various industrial products such as automobiles, home appliances, audio equipment, office equipment, agricultural machinery, and precision machinery.
