Key Advantages of St. Marys Carbon HALO Rings:
- Self-Lubricating – Our HALO™ rings 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 HALO™ rings will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.
- High Thermal Conductivity – Our HALO™ ring 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 HALO™ rings to be used in a variety of harsh environments while still maintaining performance and increasing your equipment’s uptime.
- Anti-Welding/Melting: As our HALO™ rings 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 HALO™ rings to be used in harsh environments while maintaining performance.
