What Exactly Are Wheel Bearings?

At their core, wheel bearings are precision-engineered mechanical components designed to facilitate rotation while minimizing friction. They are typically located inside the wheel hub, a central part of your wheel assembly. Imagine them as a set of small metal balls (ball bearings) or tapered rollers (tapered bearings) held within small rings or races. These tightly packed steel balls or rollers allow the wheel to spin freely around the axle with minimal resistance. Each bearing is encased in a protective seal, which keeps lubricants in and contaminants like dirt and moisture out, crucial for their longevity and performance. The quality and design of these small components directly impact your vehicle's handling, fuel efficiency, and overall safety.
