Graphite Metallizing Corp.: LARGEST GRAPHALLOY® SPLIT PILLOW BLOCK BUSHING EVER MADE

Wednesday, September 10, 2008

A Graphite Metallizing steel mill customer
recently installed 12 “super-sized” GRAPHALLOY® bushings for the main drive shaft
in their quench tank.
The Model 478 GRAPHALLOY® split pillow block design has a bore ID of 6.00 inches —
the largest ever produced by Graphite Metallizing. These pillow blocks are used to
support the sprockets that drive the chains pulling molten billets through the quench
tank.
Each of the dozen pillow blocks that the mill ordered weighs more than 250 lbs. and
must function under difficult operating conditions: complete submersion in heated,
contaminated water while supporting 10,000 lb. loads at 10 RPM.
GRAPHALLOY® bushings can withstand temperatures ranging from cryogenic to
+540 degrees C (1000 degrees F) and are dimensionally stable even when submerged or
under load. They can be used to solve difficult application problems involving high
temperatures, as well as acidic, corrosive and wash-down environments. Because of
their long life and self-lubricating qualities, they are especially suitable for installations
that cannot be accessed easily, or where performing regular maintenance is difficult.
