Tapered roller bearings (TRBs) from the 302 series (metric design) are widely used in automotive drivetrain systems due to their ability to handle combined radial and axial loads. These bearings feature a conical geometry with optimized contact angles (12°-14°) for balanced load distribution, making them ideal for:

  • Transmissions (input/output shafts)

  • Differentials (pinion gear support)

  • Wheel hubs (paired configurations)

  • Steering systems
