According to Graphite Metallizing Corp. (Yonkers, NY), its GRAPHALLOY® Type 1017 Self-lubricating Split Bushings are ideal for screw conveyor applications. 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, alkalies, hydrocarbons, or liquid gases. GRAPHALLOY does not deform under load and maintains dimensional stability. Other features of the 1017 include:
- Long life and low friction characteristics.
- No oil to contaminate the conveyed materials and are particularly suitable for screw conveyor installations including agitator or batch mixers.
- The ability to withstand dust, chemical attack, caustic liquids and high temperature environments. They provide superior performance in continuous duty operations and in applications where maintenance intervals are infrequent, or where useful life must be prolonged.
- Grades available for temperatures to 750 degrees F in air, and special grades provide reliable service up to 1,000 degrees F and higher in non-oxidizing atmospheres.
