GRAPHALLOY®
GRAPHALLOY PROVIDES CART WHEEL SOLUTIONS IN EXTREME ENVIRONMENTS
DS2529-5
GRAPHALLOY bushings and mounted units have provided solutions to cart wheel
applications ranging from high temperature furnace carts to carts used in harsh
chemical environments.
LUMBER CARTS
Process changes have created problems with the lubricant in the cart wheels
used in making pressure treated lumber. The grease was washed away by the new
chemicals used in the pressure vessel. Self lubricating GRAPHALLOY eliminated
the need for grease and solved the problem providing reduced maintenance, longer
bearing life and increased production.
FURNACE CARTS
Bronze Bushings were failing in a car bottom steel ingot heating furnace.
With loads of up to 100,000 pounds and temperatures of more than 700oF,
the oil failed to keep the bushings lubricated. There was oil on the floor that
created a hazardous situation for the workers. GRAPHALLOY bushings were fitted
into the housings to accept the axles of the cart wheels. The bushings have
operated for more than two years with no sign of wear.
ALUMINUM HEAT TREAT OVEN
GRAPHALLOY 163 style pillow blocks are being used on carts in an aluminum
heat treat oven at temperatures of more than 900oF. Roller bearings
and metal bushings were tried, but the random failures continued, causing
expensive, unscheduled downtime. The life of the cart wheels has been extended
since being fitted with the GRAPHALLOY Pillow Blocks.
Bearing failures due to harsh chemical environments and extreme temperatures
can be eliminated with an upgrade to GRAPHALLOY bearings, bushings, mounted
units and cam followers. Our staff of experienced applications engineers are
here to help you solve your toughest bearing problems.
