The High Temperature Bearing and Bushing Solution


GRAPHALLOY®, 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.
Use GRAPHALLOY Bearings and Bushings 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 Bearings and Bushings have solved problems, reduced costs and downtime, and increased productivity in high temperature applications.


High Temperature Bearings Solve Problems in 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.
