Wheel hub bearings are responsible for supporting the weight of a vehicle and allowing the wheels to rotate smoothly. There are two main types of wheel hub bearings: ball bearings and tapered roller bearings.
Ball bearings are the most common type of wheel hub bearing and are typically used in cars, trucks, and SUVs. They consist of a series of small balls housed in a ring, which allows for easy rotation.
Tapered roller bearings, on the other hand, are used in heavy-duty vehicles like trucks and commercial vehicles. They consist of two cup-shaped rings with tapered rollers in between.
When it comes to certifications, wheel hub bearings can be either OE (Original Equipment) or aftermarket. OE wheel hub bearings are manufactured by the same company that made the vehicle, while aftermarket bearings are made by a third-party manufacturer.
It is important to note that OE wheel hub bearings are generally of higher quality and come with a warranty. However, aftermarket bearings can often be more affordable and offer a wider range of options.
To ensure the longevity of your wheel hub bearings, it is important to have them regularly inspected and lubricated. Signs of a potential issue include grinding or humming noises, vibration while driving, and uneven tire wear.
In conclusion, wheel hub bearings are a critical part of a vehicle's suspension system and come in different types and certifications. Regular maintenance and inspection can help ensure their proper functioning and longevity, ultimately keeping you safe on the road.
