CARBON GRAPHITE INDUSTRIAL BRUSHES MANUFACTURING

St. Marys Carbon Brushes are manufactured from the highest quality carbon graphite, electrographite, resinbonded graphite, copper graphite, silver graphite and other metal graphite materials to suit your specific OEM or aftermarket application. All of our brushes, from the blending of raw materials to the finished product, are made in-house by our specialized craftsmen.

Each of our industrial brushes can be custom-manufactured to your specific requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to find the right brush grade or develop new grades to optimize your product’s performance, reduce wear and decrease costly maintenance.

ENVIRONMENT, OPERATING CONDITIONS & APPLICATIONS

High Conductivity

HIGH CONDUCTIVITY

Only the purest metals and materials are used to provide for consistently high conductivity and our ability to custom-design means that we can adjust the mix of our materials to meet your specific conductivity needs.

Self Lubricating

SELF-LUBRICATING

Our brushes 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.

Anti Welding Melting

ANTI-WELDING/MELTING

As our brushes 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.

Oxidation Resistant

OXIDATION-RESISTANT

Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing our brushes to be used in harsh environments while maintaining brush performance.

KEY END PRODUCTS

Our Industrial Brush products are used in manufacturing processes to develop a wide range of end products. 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.

Mechanical Seal

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…

Bearing Life

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 …

Graphite Conductivity

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 …
