Tapered roller bearings are widely used in vehicles, particularly in wheel hubs, transmissions, and differential systems. Their ability to handle both radial and axial loads makes them ideal for supporting the weight of the car while managing cornering forces. In wheel hubs, they ensure smooth rotation and durability under varying road conditions. In transmissions, they support gear shafts, reducing friction and improving efficiency. Their robust design also makes them suitable for heavy-duty trucks and off-road vehicles, where high load capacity and reliability are essential.
