3.Lubricating sliding brass bush oilite bearing sintered maintenance free
It is a self-libricating bearing materials suitable for high load low speed application which lubrications is difficult or need dry running. It is made by advanced powder metallurgy. It is based on three metal alloy types, bronze , iron and nickel each containing dry solid lubricant like graphite, molybdenum disulphide which uniformly dispersed within the metal matrix. The percentage, type and form of the solid lubricant is determined by the bearing application operating requirements in terms of specific load, sliding speed, temperature and other environmental factors.
