TCB300 Bimetal Bushing

TCB300 Bimetal  Bushing
Its material structure is Steel + CuPb10Sn10 + Graphite. The alloy surface is rolled to diamond oil grooves. The special lubricant is embedded in the grooves. It has good lubricating and corrosion resistance property. It can work in the condition of little of oil or none of oil. It is particularly applied to high temperature, water solution and the occasions where cannot be added oil.
