Wheel Bearing
Mitsubishi FUSO®

The wheel bearing, also known as the hub bearing, is a critical component of a commercial truck's wheel assembly. It is responsible for supporting the weight of the vehicle and enabling smooth rotation of the wheel. The wheel bearing is a set of steel balls or rollers held together by a metal ring, which is then mounted inside the hub assembly. The bearing is lubricated with grease to reduce friction and prevent wear and tear. The wheel bearing is subjected to constant stress and strain, especially when the truck is carrying heavy loads or traveling over rough terrain. A worn or damaged wheel bearing can cause a variety of problems, including excessive noise, vibration, and uneven tire wear. In extreme cases, a failed wheel bearing can cause the wheel to come off while driving, leading to a dangerous and potentially deadly situation. Regular maintenance and inspection of the wheel bearings is essential to ensure the safe and reliable operation of a commercial truck.
