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.

GRAPHLON GM 860® — An Abrasion-Resistant Pump Bushing Material

GRAPHLON GM 860® is an abrasion-resistant bushing material that protects pumps and helps prolong pump life. Developed by Graphite Metallizing, the material is a tough, polymer/graphite-based alloy used in the manufacture of pump bushings and other critical-wear parts.

GRAPHLON GM 860® provides exceptional abrasion resistance in harsh environments, has high compressive strength and can handle temperature extremes from -100˚ F to 300˚ F  (-75˚ C to 150˚ C). It is inert to most noxious chemicals, including acid mine water, hydrogen sulfide and jet fuel, and does not swell in water.

GRAPHLON GM 860® was developed as a replacement for traditional pump materials which are prone to damage from highly-abrasive suspensions. River water pumping stations and down hole sump pumps are two examples of key applications. The material also performs exceptionally well under both dry running and severe-duty abrasive-contaminated conditions.

Graphite Metallizing Corp., established in 1913, produces GRAPHALLOY® a graphite/metal alloy bearing material used in the manufacture of self-lubricating bearings and components for machinery and process systems.
