GRAPHALLOY®
The High Temperature Bearing Solution
GRAPHALLOY is ideally suited to applications where temperatures are too high to permit the use of oil or other lubricants. GRAPHALLOY will not soften at high temperatures or extrude under load. Many grades are suitable for temperatures to 750o F in air, special grades give good service up to 1000o and higher in non-oxidizing atmospheres. Use GRAPHALLOY in bakery and industrial ovens, glass plants, conveyors, 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 has solved problems, reduced costs and downtime, and increased productivity in high temperature applications. | |||
Pulp and Paper Industry High Temperature Conveyor Savings of More than $10,000 |
|||
| GRAPHALLOY has delivered over $10,000 in savings per year for one pulp mill. The lime kiln conveyor, operating at more than 650 degrees, 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. |  |
||
Glass Manufacturer Saves Over $20,000 with GRAPHALLOY High Temperature Cam Follwers |
|||
| For this glass cook top manufacturer, cam followers were failing on a conveyor that traveled through an oven at more than 600 degrees. 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 |  |

GRAPHALLOY Performs in High Temperature (1500ºF) Metals Reclamation Vacuum Furnace |
|||
| A mill reclaiming metals such as titanium feeds metal powders into a drum heated to 1500ºF. 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 GRAPHALLOY's ability to perform in extreme temperatures. | |||
GRAPHALLOY Solves Problems in a High Temperature, Dusty Steel Mill Cooling Bed |
|||
| 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. |
