A wheel bearing is a set of steel balls held together by a metal ring called a race. They help wheels spin fast with as little friction as possible. They are used on all kinds of vehicles, from bicycles to aircraft and cars. On a car, a wheel bearing rides on a metal axle shaft and fits tightly inside the hub, which is a hollow chunk of metal at the center of the wheel. The hub holds the lug bolts that you use to bolt the tire onto the wheel. The wheel bearing is pressed into the hub from the back.

Features

• Robust, light-weight and coated flange: avoids galvanised corrosion for easier wheel replacement and longer bearing life.
• Accurate bearing pre-load using orbital rolling techniques: provides correct operating conditions for optimum performance and durability.*
• High stiffness: ensures a smoother drive and better vehicle handling.
• Correct induction-hardening processes: strengthens raceways and avoids hub fractures for safety and long service life.
• High tensile strength wheel studs: prevent wheel-off conditions.
• Multiple-lip seal design: keeps contaminants out and grease inside the hub.
• Patented glass-fibre reinforced polyamide cages: resist high loads and operating temperatures.
