GRAPHALLOY
®
Finds Its Place In Renewable Energy
GRAPHALLOY bearings are helping to solve the world's energy needs. The advantages of alternate
power sources are well-documented. However, because of the extreme nature of the environments
required to generate power, it often becomes impossible to use traditional bearings. For years,
Graphite Metallizing has been supplying products to companies involved in the production of
clean, renewable energy. GRAPHALLOY has proven to be tough enough for these applications. Here
are a few examples:
Tidal Power
Tidal power provides an inexhaustible source of renewable energy. A company in New England
was seeking low maintenance bearings for a turbine shaft suspended forty feet below the ocean
surface. As the tides move in and out, the turbines spin and generate power. GRAPHALLOY
bearings proved ideal for this application because they operate successfully in submerged
conditions and tolerate abrasive environments like salt water.
Geothermal Power
Geothermal power offers an unlimited source of non-polluting power. GRAPHALLOY provided a
solution to the largest geothermal power field in the world by developing a special grade
bearing for this severe service. After 25 years, GRAPHALLOY bearings continue to be a critical
component of geothermal power generation.
Solar Power
Solar power has proven to be the "ultimate" in renewable energy. GRAPHALLOY bearings are
being used in this high temperature application allowing panels to slowly follow the sun while
generating high temperature steam.
Biodiesel Power
The conversion of bio-waste to fuel saves barrels of petroleum. High temperature and
an inert atmosphere can convert bio-mass and used cooking oils into biodiesel fuel. Standard bearings
fail in this hostile environment. To solve this problem, the engineers at Graphite Metallizing
developed a special high temperature grade of GRAPHALLOY and a special mounting to house the bearings.
