Tapered roller bearings are widely used in various industries due to their ability to handle combined radial and axial loads efficiently. Their unique conical design allows them to manage high thrust and radial forces while maintaining precise alignment. Below are some key applications:

1. Automotive Industry

Wheel Hubs: Commonly used in cars, trucks, and SUVs to support wheel rotation while handling radial (vehicle weight) and axial (cornering forces) loads.
Transmissions & Differentials: Helps in managing gear loads and reducing friction.
Axle Systems: Used in heavy-duty trucks and trailers for better load distribution.

2. Industrial Machinery

Gearboxes: Supports high-speed rotation while handling radial and thrust loads.
Conveyor Systems: Used in heavy-load applications like mining and material handling.
Pumps & Compressors: Ensures smooth operation under varying load conditions.

3. Aerospace & Defense

Aircraft Landing Gear: Handles heavy loads during takeoff and landing.
Helicopter Rotor Systems: Supports high-speed rotation with precision.

4. Railway & Transportation

Locomotive & Freight Car Axles: Provides durability under heavy loads and vibrations.
High-Speed Trains: Ensures stability and reduces wear.

5. Construction & Heavy Equipment

Cranes & Excavators: Supports heavy axial and radial loads in dynamic conditions.
Mining Equipment: Used in drills, crushers, and earth-moving machinery.
