High Temp Bearings: A Guide to Robust Operations in Extreme Environments
High temp bearings are a vital component in various industries that operate in high-temperature environments, including iron and steel production, petrochemical processing, and aerospace. These bearings are designed to withstand extreme heat, friction, and wear, ensuring reliable and efficient performance.
Understanding the Basics
High temp bearings are typically made of specialized materials, such as high-temperature plastics, ceramics, and specialized alloys. These materials provide exceptional thermal stability, reducing expansion and maintaining structural integrity in high-temperature conditions.
| Material | Temperature Range (Celsius) |
|---|---|
| PEEK (Polyetheretherketone) | Up to 260 |
| PPS (Polyphenylene sulfide) | Up to 240 |
| Torlon (Polyamide-imide) | Up to 275 |
| Ceramic (Silicon nitride) | Up to 1,093 |
| Alloy 718 (Nickel-alloy) | Up to 650 |
