Key Advantages of St. Marys Carbon Silver Dot™ Dryer & Hanger Bearings:

In addition to our patented materials that make Silver Dot last longer than any other dryer bearing on the market, below are other key properties of Silver Dot bearings:


Silver Dot bearings are self-lubricating, meaning that a separate lubricant is not required, which allows them to be used in both dry-running and sanitary applications.

High Thermal Conductivity

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

Low Friction / Wear

The self-lubricating properties of Silver Dot Bearings will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.

Stability at High Temperatures

Our proprietary mix of carbon graphite is able to withstand extreme temperatures, which allows Silver Dot bearings to be used in a variety of harsh environments while still maintaining performance and increasing your equipment’s uptime.


Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing Silver Dot bearings to last longer even in harsh environments.


As our Silver Dot 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.

Unmatched Quality and Service

We take great pride in the quality of our Silver Dot products and the service that each of our Silver Dot customers receive. In fact, we are so confident that we offer product and service guarantees that no other dryer bearing manufacturer can match:
