Cusn7zn4pb7-c is a high lead tin bronze cast by German standard. The standard is DIN EN 1982-2008 copper and copper alloy. Ingots and castings
The company to rely on technological progress, the use of the advanced process, introduced advanced equipment; committed to the purpose of lubrication bearings is oilless and the development of new materials developed different areas.
Cusn7zn4pb7-c Is considered bai as a "standard" bearing material of lead, tin, copper. The alloy has excellent processing DAO properties, good hardness Zhuan, strength and wear resistance, shu excellent wear resistance. Typical applications include bearings, gaskets, bushing, auto parts, main shaft bearing, machine tool bearings, crane bearing, trunnion bearing, roller bearing neck, rolling mill bearings, the sleeve is the fuel pump and pump shaft sleeve, diesel engine piston pin bushing, forging toggle lever bearing, stuffing box hydraulic press, hydraulic press mainlining, pump impeller, gm liner, fitting, pump assembly, outer spherical bearings, and so on.
C93200 self-lubricating bearings made of bronze material, has the alloy has excellent processing performance, good hardness, strength and abrasion resistance, excellent abrasion resistance, because its material composition lead is higher, so the oxidation resistance of the bearing, and bearing performance, high levels of lead but with environmental requirements of components and the working environment will not be able to apply.

his alloy has high mechanical properties, wear reduction properties and corrosion resistance, free cutting, brazing and welding properties, small shrinkage coefficient, no magnetic.Green zd copper bushing, axle sleeve, antimagnetic element and other coatings can be prepared by wire flame spraying and arc spraying.High strength, corrosion resistance and excellent
Self-lubricating bearing is the basic working principle of solid lubricant on the surface of the bearing in the early operational stage due to the friction of ask each other to form a transfer film and coat the to eventually form solid lubrication film on the grinding parts to achieve the purpose of self lubrication, which partition the direct contact between the workpiece and good protection of grinding extend the service life of the bearing and artifacts.
Note: since there is oil groove or no oil groove in the C93200 bronze bearing,
please select the appropriate bearing lubricating grease or the lubricating oil to achieve the best self-lubricating effect according to the speed, operating temperature, noise reduction, water resistance and load of the bearing.
