The aircraft engines’ turbines and compressors, etc., all require bearings. The bearings in aircraft engines mainly support the rotating shafts to ensure efficient operation. These extreme conditions require the bearings to have excellent high-temperature resistance, high speed, lubricity, and other properties to ensure the efficient and stable operation of the aircraft engine.
The aircraft’s main rotors and ailerons need bearings to withstand large loads and radial loads in extreme environments. So they place high demands on the bearings' load capacity, vibration resistance, and corrosion resistance, etc.
Avionics equipment includes aircraft navigation systems, control systems, sensors, and so on all requiring bearings. These components need bearings to support the operation of electronic equipment. So the bearings require high precision, reliability, low friction, and other properties.
In the aerospace industry, the rocket engine’s propulsion system and the booster’s rotating parts also need bearings. These engines work in extreme environments. Therefore, the bearings used in boosters and rocket engines need to have high strength, high pressures, and high loads to improve reliability and durability.
