GRAPHALLOY® Flange Blocks Improve Damper Reliability in Ammonia Facility SMR Operations

A major ammonia production facility upgraded the damper actuators on its steam methane reformers with GRAPHALLOY flange blocks and copper-grade bushings, replacing roller-element bearings that were failing in high-temperature, contaminated air. The plant had seen more than three years of reliable operation from GRAPHALLOY components in a similar installation and chose the same solution for this project. The new assemblies were installed in March 2025 and are performing as expected in temperatures up to 420°F.

Sump Pump Case Study

 A refinery facing constant bearing failures in its vertical oily wastewater sump pump found a long-term solution with GRAPHALLOY self-lubricating bushings. By replacing the original bronze bearings with our bronze-grade, spiral-grooved design, the facility eliminated shaft wear, leakage, and contamination concerns. Two years later, the pump is still performing reliably.

 When textile bearings face heat, caustics, and constant motion, Graphalloy is built to last. Engineered from a graphite-metal alloy, these bearings thrive where grease and polymers fail — from dyeing tanks and ovens to laminators running at 450 °F. The result: no lubrication, no measurable wear, and five-times longer life. For textile plants chasing reliability and uptime, Graphalloy means fewer shutdowns and more production.

Proven Performance in High-Temperature Tortilla Ovens and Cooling Conveyors

Food manufacturers operating high-speed tortilla ovens and cooling conveyors face extreme heat, moisture, and constant motion. Conditions that can quickly destroy traditional bearings.

Recent applications in both a European snack facility and a North American equipment manufacturer demonstrate how Graphalloy® self-lubricating bearings perform where standard graphite and roller bearings fail.

By engineering custom-fit solutions capable of operating dry or submerged and handling continuous temperatures above 750°F (400°C), these projects achieved dramatic results:

• Up to 80% reduction in bearing failures
• Lower maintenance and downtime
• Improved productivity and reliability

These case studies showcase the strength of Graphalloy’s high-temperature bearing technology in food production environments that demand both performance and compliance with FDA-acceptable standards.

GRAPHALLOY Solves Bearing Seizures in Steel Mill

Bearing problems? One steel mill had them — and lots of them. Greased roller bearings in their guide rolls were seizing under high heat (170–180°C), causing maintenance headaches and production delays.

Their team turned to GRAPHALLOY® bushings, a graphite/metal alloy that doesn’t require grease and thrives in high temps. After six months with GRAPHALLOY in place, the plant manager gave a glowing review: “They’re performing very well.”

Now they’re upgrading all the guide rolls.

Proven reliability in high-temperature glass applications

Graphalloy® self-lubricating bearings perform where conventional bearings fail.

• 
  Operate up to 1000°F without grease
• Resist corrosion, dust, and contamination
• Extend service life and reduce downtime

In one glass application, Graphalloy cam followers lasted over 4× longer—saving more than $15,000 annually.
