Wheel bearings are an essential part of your vehicle's steering and suspension system. Wheel bearings are responsible for keeping the wheels attached to the vehicle. They allow each wheel to spin freely and at the desired speed. Wheel bearings take a steady amount of abuse. They support the entire weight of your vehicle while traveling over rough roads, potholes and other rugged terrain. Wheel bearings are one of the longest lasting steering and suspension parts, but it really depends on driving habits, driving conditions and other factors.
Truck hub units, which contain two tapered roller bearings, are pre-adjusted, greased and sealed at the factory in order to simplify installation. The wheel bearing units are intended for use in truck, trailer and buses. They are designed to withstand typical harsh operating conditions and require less maintenance than the conventional wheel bearing sets they replace. Some variants have an integrated impulse ring which makes some variants suitable for use with anti-lock braking systems. The units can also save time and cost during brake maintenance.
