GRAPHALLOY® Retrofit Delivers 15% More Flow and 80% Less Vibration in Overhung FCC Pumps

 An East-Coast refinery was living with chronic vibration and bi-weekly overhauls on its two-stage overhung feed pumps. Swapping the steel wear rings and bushings for GRAPHALLOY® self-lubricating parts turned the story around:

Nuclear energy demands components that never flinch—whether they face 1000 °F (535 °C) steam, borated water, or unplanned dry-running events. GRAPHALLOY® self-lubricating bearings meet that challenge by combining the strength of metal with the lubricity of graphite.

GRAPHALLOY® Bearings From Frequent Failures to Four Years of Reliability in Snack Food Fryers

 In their continuous fryer systems, manufactured by Heat & Control®, this producer faced recurring failures with greased ball bearings. Bearings used on belts and paddles in the fryers experienced extreme conditions:

• Exposure to 400°F
• Continuous splashing with hot oil
• Full submersion in cooking oil for certain locations

Despite regular re-greasing, the bearings on the hold-down belt had to be replaced every 3 to 4 months. Maintenance was costly, and unplanned downtime was disruptive.

Graphalloy® “Can” Do It!

 In early January, a leading aluminum beer-can producer approached Graphalloy to upgrade the roller bearings in their heat-treating ovens. After installing our self-lubricating pillow block assemblies, they’ve enjoyed eight weeks of maintenance-free, grease-free operation with zero failures or contamination. Impressed by the results, they’ve requested a quote for 26 additional units to roll out the solution across their production line.

Bearings for Extreme High Temperatures

Many bearing materials claim to be high temperature performers, but on closer inspection, they can't perform in the temperatures required for ovens, furnaces, and more. But Graphite-metal alloys are true high temperature performers, with the ability to reach temperatures of 750°F (400°C) and higher. This material is used in steel mills, food ovens, heat treat furnaces, molten sulfur pumps, roasters, and more, due to its ability to handle extreme heat and stay self-lubricating.
