What are Tapered Bearings and Why Use Them? Tapered bearings use rollers shaped like flat-topped cones and two races angled from the outside in of the bearing. This angle makes the bearing better at handling forces exerted on the bearing during cornering (known as axial load) in trucks and large cars. Your model came from the factory with tapered bearings. Roller ball bearings work well for smaller cars, but replacing a tapered bearing with a roller ball bearing increases wear and failure.
