In aerospace, tapered roller bearings are used in aircraft landing gear, helicopter rotor systems, and jet engines. They must withstand extreme forces, high speeds, and temperature variations while maintaining precision. Their tapered geometry helps distribute loads evenly, enhancing performance and safety. In landing gear, they absorb impact during takeoff and landing, while in engines, they support rotating components under high stress. Their lightweight yet strong construction makes them ideal for aviation applications where reliability is critical.
