2 needed per car

By the early 1980s, demand was still growing for ever-shrinking, fully integrated designs. The HBU3 offered it by incorporating a flange for wheel and brake rotor attachment and a second flange for fixing the unit to the suspension.

The unit incorporates further reductions in weight, noise, vibration and assembly time for driven and no-driven wheels on vehicles including the Alfa Romeo Giulia, Fiat 500X, Jeep Renegade, Dacia Duster, Mini Cooper, BMW 7 (E65), Audi A6, VW Passat V and Opel Insigna and Astra H.

Features and performance

• Separate inner ring on the inboard ball row: maximises the dynamic load carrying capacity.
• 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 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.
• SKF GHG Grease: exclusive formula ensures low operating friction.
