GRAPHALLOY ®
The High Temperature Bearing and Bushing Solution



Graphalloy pillow blocks and flange blocksGRAPHALLOY®, a graphite/metal alloy, is ideally suited to applications where temperatures are too high to permit the use of oil or other lubricants. GRAPHALLOY High Temperature Bearings and Bushings will not soften at extreme temperatures or extrude under load. Many grades are suitable for temperatures to 750°F (400°C) in air. In addition, special grades provide service up to 1000°F (535°C) and higher in non-oxidizing atmospheres.

Where to use Graphalloy High Temperature Bearings and Bushings

Use GRAPHALLOY Bearings and Bushings in bakery and industrial ovens, glass plants, conveyors, dampers, 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.

Here are examples of how GRAPHALLOY Bearings and Bushings have solved problems, reduced costs and downtime, and increased productivity in high temperature applications:
 

Solves Problems in Bakery Ovens

 

high temperature bearings for bakery ovensA division of a large food manufacturer specializing in frozen pizza was experiencing difficulties with the operation of their bakery ovens. The conventional oil-lubricated bearings being used in the ovens were lasting only one week. The customer had been replacing 16 to 20 burned-out bearings every seven days for over one year.

GRAPHALLOY high temperature bearings were installed. Many months later, these bearings did not show any signs of wear.

Delivers Savings of More than $10,000 in Pulp and Paper Industry

 

high temperature oven bearings
GRAPHALLOY has delivered over $10,000 in savings per year for one pulp mill. The lime kiln conveyor, operating at more than 650°F (343° C) had bearing failures every few months.

As a result, maintenance costs were rising and production was declining. The use of GRAPHALLOY Bearings eliminated the additional maintenance and increased productivity.
 

Saves Glass Manufacturer Over $20,000
 

high temperature bearings for glass cook tops
For this glass cook top manufacturer, cam followers were failing on a conveyor that traveled through an oven at more than 600°F (316°C). The high temperature grease lubricant being used was inadequate. Maintenace costs were high at $100 per hour.

Once GRAPHALLOY Cam Followers were installed, the manufacturer realized a savings in maintenance costs of over $20,000 per year.
 

Performs in Metals Reclamation Vacuum Furnace
 

A mill reclaiming metals such as titanium feeds metal powders into a drum heated to 1500ºF (816°C). The drive shaft spinning the drum is supported by two GRAPHALLOY Pillow Blocks. In addition, GRAPHALLOY Bushings are in the 12 wheels that support the drum as well as the worm gear. This application demonstrates the ability of GRAPHALLOY Bushings to perform in extreme temperatures.

 
 

Solves Problems in Dusty Steel Mill Cooling Bed

  high temperature bearings in steel mills
This Midwestern steel mill was using GRAPHALLOY Bushings for the horizontal rollers in their cooling beds. The bushings were thriving under severe heat and water spray conditions. Because of the success with the horizontal rollers, the mill wanted to consider GRAPHALLOY Flange Bearings for another application: the vertical guide rollers along the sides of the cooling beds used to keep the hot steel from running off the sides. Guide rollers remain static until a piece of hot steel slams up against them, at which time they are expected to turn instantly to guide the steel back onto the cooling bed. This mill had been using conventional greased rolling element bearings in the vertical guides that were lasting only a few months. Based on the success with the vertical rollers, the mill has since retro-fitted additional lines with GRAPHALLOY. Read about a steel bleeder valve application here.
