Wheel bearings have a very important job – enabling the rotation of your wheels. They make sure your wheels run smoothly with minimal friction. They also maintain correct wheel tracking and can even play a role in providing your vehicle’s drive systems with wheel speed sensor signals.
One side of the bearing rotates with the wheel while the other side is fixed to the suspension. The rolling elements in bearings carry vehicle load and ensure minimal-friction rotation between the inner and outer races. In automotive bearings, there are two types of rolling elements: ball bearings and roller bearings.
Ball bearings are used in applications where speed is more important than load. They have a small point of contact, which provides less rolling resistance and lighter load carrying capabilities.
Roller bearings, on the other hand, have a large point of contact, which makes them ideal for carrying higher loads. These bearings have many shapes and come in cylindrical, spherical, tapered and needle styles.
