Carbon Graphite Rotors & Vanes

St. Marys Carbon manufactures a variety of different sizes and types of carbon graphite rotors & vanes. We will develop a complete set of rotors & vanes for you or we will simply custom-develop vanes to fit any of your specialty rotors made from other materials. Our rotors & vanes provide lubrication without the use of oil or any other contaminating lubricants, which makes them ideal for your dry-running or sanitary environments.


Our rotors & vanes are made from the following materials:

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

Custom Solutions

If you require a customized solution, we can manufacture our carbon graphite rotors and vanes to your specific requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to create a carbon graphite product that is right for you.

Key Advantages of St. Marys Carbon Rotors and Vanes:

Stability at High Temperatures

Our proprietary mix of carbon graphite is able to withstand extreme temperatures, which allows our rotors and vanes 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 rotors and vanes will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.

High Thermal Conductivity

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

Dry-Running / Oil-less

Our rotors and vanes are self-lubricating, meaning that a separate lubricant is not required, which allows them to be used in not only dry-running but also sanitary applications.


As our rotors and vanes 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 rotors and vanes to last longer even in harsh environments.
