The inner surface of the blind hole oil storage steel bushing is sprayed with molybdenum disulfide, which has the advantages of low friction coefficient and good wear resistance, and can work under the condition without oil or with little oil. Products are widely used in construction machinery, heavy duty high load equipment.
Process: Multipurpose furnace carburizing
Thickness of carburized layer:1.5-2.0mm
Hardness of carburized layer:HRC60--62
