JDB-3 product description
JDB-3 steel-bronze lubricated inlaid bearing is a solid lubricating product in which tin bronze powder is sintered in the base of the steel sleeve and then embedded with solid lubricant. In addition to the functions of JDB-2, it can save costs and improve compressive strength. . Its end face can be welded and installed with the base, so it is suitable for metallurgical machinery, construction machinery and oil transportation machinery and other fields that cannot be refueled.
