JDB-600 copper sleeve is a surge of oil as a lubricating oil groove of high strength brass bearings. The product has a traditional bronze bearing function, the use of high-strength brass (ZCuZn25Al6Fe3Mn4) after his HB hardness doubled, so the use of the product in the low-speed situations, bronze sleeve than doubled life can be extended, and its bearing pressure, able to adapt to heavy duty applications. Customers can request the product to provide high strength brass, bronze, extra-hard high-strength brass, bronze, lead, and other relevant materials. Material can provide 663 sets of tin bronze copper alloy matrix, which has high mechanical properties, anti-friction properties and corrosion resistance, shrinkage coefficient is small, non-magnetic,? Tin bronze in the atmosphere, water, fresh water and steam is very corrosion resistance, widely used in steam boilers and ship parts and high-precision machine tools and wear parts elastic parts.
