Carbon Graphite Bearings & Bushings

We custom manufacture many sizes of carbon graphite bearings and bushings used in a variety of support and motion applications. We offer many different types of bearings, including radial, axial/thrust and sleeve, especially beneficial in any type of dry-running, harsh (e.g., high temperature, chemically corrosive) and sanitary environments.


Our bearings and bushings are made from the following materials:

We also offer various impregnations and treatments to further fit your application needs.

Custom Solutions

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.

Key Advantages of St. Marys Carbon Bearings / Bushings:

Stability at High Temperatures

Our proprietary mix of carbon graphite is able to withstand extreme temperatures, which allows our bearings to be used in a variety of harsh environments while still maintaining performance and increasing your equipment’s uptime.

Low Friction / Wear

The self-lubricating properties of our bearings will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.

High Thermal Conductivity

Our bearing materials allow for heat exchange which will prevent overheating and most importantly will not cause damage to your equipment.


Our bearings are self-lubricating, meaning that a separate lubricant (e.g., oil) is not required, which allows them to be used in both dry-running and sanitary environments.


As our bearings can withstand high temperatures, they are resistant to melting or welding to your equipment during operation, allowing your equipment to run longer and perform better.


Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing our bearings to last longer even in harsh environments.
