What are high temperature bearings mainly used for?

High temperature bearings are primarily used in applications where equipment operates under elevated temperatures that can degrade standard bearings. They are designed to withstand extreme heat, often exceeding 200°C (392°F) and sometimes reaching up to 1000°C (1832°F), depending on the type.

Common uses include:

1. Aerospace Engines: Supporting turbine shafts and other components in jet engines and rocket engines, where temperatures are extremely high.
2. Industrial Furnaces and Kilns: Facilitating rotation and movement of parts within high-temperature environments.
3. Power Generation: In gas turbines and other high-temperature turbines.
4. Metal Processing Equipment: Such as rolling mills, where equipment is exposed to intense heat.
5. Chemical and Petrochemical Industries: Where reactors and processing equipment operate at elevated temperatures.
6. Automotive Turbochargers: Which operate under high thermal conditions.

Their main function is to maintain reliable operation and longevity in environments where standard bearings would fail due to heat-related degradation. They achieve this through specialized materials, lubricants, and design features that tolerate high temperatures.
