GRAPHALLOY® Pillow Blocks - The Problem Solvers

Cost-Saving Solutions for Harsh Environments

• GRAPHALLOY^® 845 series flange units have reduced maintenance costs in Chicken Roasters by more than 50% after replacing standard ball bearing units.
• 400°F temperatures caused failure in pillow blocks on a Hot Strip Mill Run Out Table.  GRAPHALLOY 448 pillow blocks were able to withstand the temperature as well as the quench spray.
• Conveyor running above a 1020°F zinc bath presented a problem for traditional bearings. GRAPHALLOY 318 flange units provided years of trouble free operation.
• A vacuum at 1500°F is an environment that most bearings cannot handle. GRAPHALLOY 963 pillow blocks have been running for more than a year without problems.
• Six years of maintenance free operation was the result of the GRAPHALLOY replacements of spherical roller bearing pillow blocks on a salt cake conveyor.
• Fish screens in the Columbia River is a great application for submersible GRAPHALLOY pillow blocks.
• Harsh chemical wash down required replacing 24 of 96 ball bearing pillow blocks on a weekly basis.  GRAPHALLOY 845 pillow blocks have run for more than six years with an annual savings exceeding $20,000.

GRAPHALLOY for Bakery Applications

High temperature GRAPHALLOY® bushings have been the choice of oven manufacturers for many years. GRAPHALLOY bushings extend bearing life and reduce maintenance costs for bakeries in temperatures reaching 1000° F (535° C). GRAPHALLOY may be the answer to the most difficult operating problems.

The Food and Drug Administration (FDA) has accepted GRAPHALLOY for "repeat use in food contact equipment" in bakery ovens, pumps, mixers and conveyors. Ovens and conveyors, in particular, undergo high heat and continuous operation that challenge the life and durability of critical components. Self lubricating GRAPHALLOY bushings and bearings perform in temperature extremes...when conventional materials fail.

GRAPHALLOY, a graphite/metal alloy, prevents unnecessary downtime and lost production. It also survives wash down conditions common in many food applications. With its low coefficient of friction and high strength, GRAPHALLOY bearings deliver long life and are not subject to seizures binding or sudden failure. In addition, the high temperature, self lubricating capabilities of GRAPHALLOY bushings reduce maintenance costs

GRAPHALLOY® Self-Lubricating Bushings for High Heat, Low Maintenance and Reduced Downtime

Graphite Metallizing Corporation announces additional sizes of the GRAPHALLOY® 453 Family of Self-Lubricating Bushings. These bushings are for severe industrial applications where temperatures reach 750° F (400° C) or higher. GRAPHALLOY, a graphite/metal alloy, bushings are designed to operate without lubrication.

The 453 Bushings have proven to be successful in a variety of high temperature applications including bakery ovens, heat treat ovens, furnaces, conveyors, overhead paint lines, glass lehrs, louvers, dampers, valves as well as other environments where oil and grease cannot be used. Applications can experience improved performance through the use of GRAPHALLOY materials.

Among their many advantages, GRAPHALLOY bushings operate at longer intervals without the need for maintenance, which reduces costly downtime. They are an excellent choice for applications where service and maintenance tasks are cumbersome or difficult to perform. Additional benefits of GRAPHALLOY include a low coefficient of friction and dimensional stability. The 453 Bushings, like all GRAPHALLOY products, do not soften at high temperatures or extrude under load. Installations of these bushings have operated for more than 10 years without maintenance.

GRAPHALLOY can be the solution to the toughest bearing, bushing, thrust washer, cam follower, or pillow block bearing design problem. It is available in over 100 grades with specific properties that meet a wide range of engineering solutions and specifications. FDA accepted grades of GRAPHALLOY are available for food contact equipment. NSF® International certified two grades of GRAPHALLOY material for use in municipal well pumps and water treatment plant applications.

In some applications, GRAPHALLOY bearings have operated for up to 20 years without maintenance. Standard designs are available but most GRAPHALLOY products are custom designed to the unique requirements of the specific application.

Graphite Metallizing Corporation is ISO certified and has produced GRAPHALLOY since 1913. For additional information about Graphite Metallizing and its products, please visit us online at http://www.graphalloy.com/index.htmlor call 914-968-8400.
