CARBON GRAPHITE PLUGS & WEAR PLATES
St. Marys Carbon custom manufactures a large variety of carbon and graphite grades for a wide range of wear applications. Our proprietary grades are necessary for many of the unique environments in which wear products are required. All of our products, from the blending of raw materials to the finished products, are made in-house by our specialized craftsmen.
We have the expertise to provide you with custom solutions to fit your specific application. Have you ever encountered technical issues or questions such as the below that requires an expert’s help?
What do you do when you require a product with multi-functionality that cannot be met with a monolithic material?
How do you enhance a metallic substrate to provide multi- level lubrication properties?
ENVIRONMENT, OPERATING CONDITIONS & APPLICATIONS
DRY-RUNNING / OIL-LESS
Greatly reduces failure rates and allows for use in sanitary environments due to its self-lubricating properties.
HIGH TEMPERATURE STABILITY
Maintains high strength and runs effectively without failure at high temperatures.
HIGH THERMAL CONDUCTIVITY
Allows for heat exchange to prevent overheating.
LOW FRICTION / WEAR
Resists wear and reduces friction as it is chemically inert, oxidation-resistant and self-lubricating.
KEY END PRODUCTS
Our Composite Multi-Modal Lubricating Products are used in a wide range of end products as listed below. Remember that we custom-design our products to fit your needs, so please contact us if you have a need outside of those below and we’ll work with you to find a solution.
- Raw Material Extraction/Breakdown (e.g. (aggregates, sand, gavel, coal)
- Recycling
- Landscaping
- Manufacturing Equipment (e.g., stamping dies)

Carbon Graphite Mechanical Seal Types
Rotating equipment often requires a dynamic mechanical seal to create a seal between a rotating shaft and a stationary body and prevent the escape of process fluid(s) including liquid and/or gas. They can also be used in mixer seals to prevent fugitive ambient particulates from entering a contained vessel being being mixed such as a pharmaceutical reaction…
Why Bearings Fail and How to Prevent It
All bearings have a fixed life expectancy. Some are replaced because of normal wear or spalling, and others need replacing because of premature wear or failure. An unexpected failure can cause damage to equipment, downtime, costly replacement, and possibly even injury. And, even before they fail, the premature wear is likely to have effects on performance …
Carbon Graphite Conductivity & Expansion
When deciding on the materials for carbon graphite components or parts, it all starts with a thorough review of the application which includes the components’ form/function/fit and property identifying the “must haves” and the “nice to haves” and melding these with a design for manufacturability. There are three important physical characteristics …
