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.

Key Advantages of St. Marys Carbon Bearings / Bushings:

  • Self-LubricatingOur 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.
  • 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.
  • 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.
  • Anti-Welding/Melting: 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.
  • Oxidation-Resistant: Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing our bearings to last longer even in harsh environments.

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.
