GRAPHALLOY® bushings work where others won't. You can replace ball bearings, metal and plastic bushings, and ordinary hard carbon bushings. GRAPHALLOY bushings reduce maintenance and downtime.
GRAPHALLOY is a self lubricating material and operates as a bearing without additional lubrication.These long-wearing bushings never need lubrication. Solid GRAPHALLOY is not simply a surface coating; it is self-lubricating; its properties do not deteriorate with wear. Because no grease or oil is used, these bushings do not attract dust or foreign matter. GRAPHALLOY bushings and bearings eliminate oil and oiling schedules; prevent oil or grease damage to products; operate in inaccessible locations or where maintenance is difficult to perform; operate well at significantly higher temperatures than traditional lubricants and plastics.
GRAPHALLOY bushings eliminate fire hazards; operate intermittently and unattended over long periods; operate where machines must be steam cleaned. They will not "spark" and are recognized as safe bearings in the explosives industry, or in explosion prone dusty atmospheres.
GRAPHALLOY bushings are available in over 100 grades with specific properties that meet a wide range of engineering solutions and specifications. The most used GRAPHALLOY materials are babbitt, copper, bronze, nickel, and silver. We also offer FDA acceptable grades for food contact equipment. Many grades are suitable for temperatures to 750o F in air, special grades give good service up to 1000oand higher in non-oxidizing atmospheres.GRAPHALLOY products are used in virtually every manufacturing industry:
GRAPHALLOY bushings are used in water, hydrocarbons, chemical and fuel oil pumps, meters, mixers, and rotary filters. GRAPHALLOY is also used for submerged bushings in cleaning fluids, weak acids, and alkalis. The textile dyeing and paper/pulp industries employ GRAPHALLOY bushing extensively.
GRAPHALLOY is not soluble in most industrial liquids. GRAPHALLOY is a preferred material for steam seals and for equipment that must be steam cleaned. No lubrication to wash away. As Bushings or Seals in water pumps, gasoline pumps, spray pumps, meters, foot bearings, mixers, dye jigs, food and pharmaceutical equipment, bleaching and washing tanks, and rotary filters; even in molten metals.

At High Temperatures
GRAPHALLOY is ideally suited to applications where temperatures are too high to permit the use of oil or other lubricant. GRAPHALLOY will not soften at high temperatures or extrude under load. Many grades are suitable for temperatures to 750o F in air, special grades give good service up to 1000oand higher in non-oxidizing atmospheres.
Plastic bearings, with high coefficients of thermal expansion, cannot maintain clearances or fail due to deformation. GRAPHALLOY conquers these problems.
Use GRAPHALLOY as bushings in bakery and
industrial ovens, glass plants, conveyors, dryers, kilns, kiln
cars, stokers, soot blowers, oil guns, gypsum board and veneer
dryers ...wherever temperatures are too high to permit
the use of oil or greases.
GRAPHALLOY Bearings are used in high speed air lubricated, gas, water, steam, gasoline, and JP4 fuel lubricated bearings. Air lubricated GRAPHALLOY Bearings have operated at 100,000
Most of our bearings are produced to a custom design for a specific application. Whatever your application, our engineers have wide experience with industrial machinery of all types; more than likely we have already developed a solution for a similar application.
When you have the design freedom to use a standard bearing or pillow block, we have a large selection of standard GRAPHALLOY parts with immediate availability. Otherwise, let us design a solution with you.
