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.
Our bearings and bushings are made from the following materials:
We also offer various impregnations and treatments to further fit your application needs.
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.

Greatly reduces failure rates and allows for use in sanitary environments due to its self-lubricating properties.
Maintains high strength and runs effectively without failure at high temperatures.
Allows for heat exchange to prevent overheating.
Resists wear and reduces friction as it is chemically inert, oxidation-resistant and self-lubricating.
