Self-Lubricating Bearing (Cu Base) (COB-SRIM 021/023)

COB-SRIM 021 Self-Lubricating Bearings

It is based on a bronze alloy of a particular formulation with a sintered bronze layer as its interlayer and with the compound of POM as its surface. It has good load capacity and wear-resistant. It is used in vehicle chassis forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry, and rolling steel industry, etc.

COB-SRIM 023 Self-Lubricating Bearings (without Pb)

It is based on a bronze alloy of a particular formulation with a sintered bronze layer as its interlayer and with the compound of POM as its surface. It has good load capacity and wear-resistant. It is used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry, and rolling steel industry, etc. It is without lead, meeting the requirements of environmental protection.
