◆ Introduction

MG-090 bronze self-lubricating bearings use a kind of high density bronze alloy of special compositions as backing, the surface of alloy is rolled with diamond pattern of the oil indents or half ball oil indents, this kind of bearing has a higher density, a higher load capacity and a better anti-wear resistant performance. It has been widely used in many fields such as hoist machine, building machinery, machine tool industry and mining machinery.
