We don’t simply machine a product to a different specification; we are able to alter the base materials and physical properties of our products to make them ideal for your needs.

Key Advantages of St. Marys Carbon Automotive Brushes:

Stability at High Temperatures

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

High Thermal Conductivity

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

Self-Lubricating

Our automotive 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

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

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