The metal-based inlay solid self-smooth bearing is a novel and smooth bearing with both metal bearing characteristics and self-smooth bearing characteristics. The metal substrate receives the load, and the specially formulated solid-smooth material has a smooth effect.

It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-smoothness. Extra-copper-based solid inlaid lubricating bearings are suitable for applications where heavy load, low speed, reciprocating or rocking are difficult to smooth and form oil film, and are not afraid of water rushing. Etching of other acids is free of oil bearing bushings and flushing. Inlaid bearings are not only fuel-efficient, but also energy-efficient and their service life is longer than that of plain bearings. Now the product has been widely used in metallurgical caster, rolling equipment, mining machinery, ships, steam turbines, hydraulic turbines, injection molding machines and equipment production lines.

The oil-bearing bearing uses metal powder as the main raw material, and the sintered body manufactured by the powder metallurgy method is more porous than the self-lubricating steel sleeve, and has the quantity, size, shape and distribution of the pores that can be freely adjusted during the manufacturing process. Technical advantages.

Using the porosity of the sintered body, it is impregnated with 10% to 40% (volume fraction) of a smooth oil and applied under the self-supply condition. During operation, the bearing temperature increases because the coefficient of expansion of the oil is greater than that of the metal, so it actively enters the sliding surface to smooth the bearing. Oil-bearings and primary oils can be used for longer periods of time and are often used in occasions where refueling is inconvenient.
