Tapered roller bearings are a type of rolling-element bearing designed to support both radial and axial loads. They have conical rollers and raceways arranged so that the rollers meet at a common point on the bearing axis. This design enables them to handle high radial and thrust loads while maintaining proper alignment. These bearings are commonly used in applications where precise rotational accuracy and high load-carrying capacity are required. Industries such as automotive, aerospace, construction machinery, and gearboxes often utilize tapered roller bearings due to their ability to provide efficient power transmission and support heavy loads under various operating conditions.
