A precision bearing assembly that enables smooth rotation of wheels while supporting vehicle weight and handling loads.
A wheel bearing is a critical automotive component consisting of high-precision steel balls or rollers housed within inner and outer races, designed to reduce friction between the wheel hub and axle. It supports radial and axial loads from vehicle weight, cornering forces, and road irregularities while maintaining precise wheel alignment and rotation. Modern wheel bearings are typically sealed, pre-lubricated units that integrate with ABS sensors and require no maintenance during service life.

Common symptoms include humming or grinding noises that increase with speed, wheel vibration, uneven tire wear, ABS warning lights, and steering wheel play.
Modern sealed wheel bearings generally last 150,000-250,000 km under normal driving conditions, but lifespan can be reduced by poor road conditions, impacts, or improper installation.
Most contemporary wheel bearings are sealed, non-serviceable units that require complete replacement when worn or damaged. Attempting to repair sealed bearings compromises lubrication integrity and safety.
