| ADVANTAGES
OF GRAPHALLOY BUSHINGS |
| Self-Lubricating During
operation, GRAPHALLOY bushings deposit a thin film of GRAPHALLOY on the shaft.
This thin film supplies lubrication which is maintained for years of continuous
operation. (No oil is required) | |
| Extremly
Durable GRAPHALLOY
busings have been in continuous service on many applications for ten to twenty
years without replacement. Their dependability has been thoroughly demonstrated. |
|
| No
Fumes Operating
at the recommended temperatures and loads, GRAPHALLOY bushings do not produce
fumes or odors which migh injure or contaminate food products. They can be used
with confidence where oil or other lubricant might cause adulteration. |
|
| Low
and High Temperature Operation GRAPHALLOY
bushings are in regular use at temperatures as high as 750o F and as low as the
temperature of liqid helium. At such high temperatures, most oils tend to carbonize
or solidify; and to thicken at low temperatures. | |
| Fire
Preventive GRAPHALLOY
bushings are invaluable for use where oil might ignite or where sparks might cause
explosion. | |
| Low
Coefficient of Friction GRAPHALLOY
bushings have a constant and low coefficient of friction. This coefficient changes
little with use because GRAPHALLOY is not a surface treatment. GRAPHALLOY contains
nothing to dry out or to become viscous or gummy. | |
| Submersible GRAPHALLOY
busings operate extremly well in fresh or salt water, gasoline, jet fuels, cleaning
fluids, solvents, bleaches, caustic solutions, dyes, hydrocarbons, liquid gases,
and most chemicals where ordinary busings would corrode or seize. GRAPHALLOY does
not swell. | |
| Low
Coefficient of Expansion Because
they are composed of a large proportion of graphite, GRAPHALLOY bushings hae a
coefficient of linear thermal expansion about one-half of steel. Accordingly,
a GRAPHALLOY busing will not seize the shaft when the temperature is reduced to
extremly low values. | |
| High
Speeds speeds
to 200,000 RPM have been attained with air or gas lubrication. |
|
| High
Loads Where
grease would be squeezed out or vibrated out, GRAPHALLOY remains in place and
does not cold flow. | |
| Linear
Motion Linear
motion wipes away oil or grease lubrication and collects contaminants. GRAPHALLOY
stay in place and lubricates. | |
| Corrosion The
thin film of GRAPHALLOY deposited on the shaft inhibits corrosion of the shaft. |
