The no-oil-supply bush is metal based bearing which used high strength brass casting （HBｓC3C）and solid lubricant. On the place, where oil supply is difficult structurally and maintenance is impossible, the no-oil-supply bush is superior in sliding and lubricity under the condition of no-oil-supply and maintenance free.
