Graphalloy Type 1017 self-lubricating split bushings, available from Graphite Metallizing, are suitable for screw conveyor applications.
Graphalloy bushings contain no oil to contaminate the conveyed materials and are particularly suitable for screw conveyor installations including agitator or batch mixers.
Type 1017 bushings are split to provide for easy installation along the conveyor.
They can withstand dust, chemical attack, caustic liquids and high-temperature environments.
They perform in continuous duty operations and in applications where maintenance intervals are infrequent, or where useful life must be prolonged.
Graphalloy, a graphite/metal alloy formed from molten metal, graphite and carbon, is insoluble in most industrial liquids and is not affected by submersion in most acids, alkalis, hydrocarbons or liquid gases.
It does not deform under load and maintains dimensional stability.
Graphalloy products work where oil-based lubricants oxidise and where plastic bushings fail or prove troublesome.
The bushings are applied in refineries, paper mills, waste-to-energy plants, glass plants, steel mills and power plants.
Grades are available for temperatures to 750F in air and special grades provide reliable service up to 1,000F and higher in non-oxidising atmospheres.
