CARBON GRAPHITE BEARINGS & BUSHINGS MANUFACTURING
St. Marys Carbon custom manufactures many sizes, shapes and quantities of carbon graphite bearings, including Radial, Thrust and Sleeve. All of our bearings, from the blending of the raw materials to the finished product, are made in-house by our specialized craftsmen.
We can custom-manufacture our bearings and bushings to your specific carbon grade requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to create a product that is right for you.
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 bearings 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.

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 …
