Wheel hub technology is developing quickly to cater for the ever-increasing requirements needed to control the modern vehicle and keep it safe. With weight saving and safety being the driving forces, manufacturers are constantly looking at new ways to reengineer the system. First Line continues to stay abreast of these trends to ensure that motor factors and installers are well-prepared, when the technologies hit the aftermarket.
THE EVOLUTION OF WHEEL BEARING TECHNOLOGY
Wheel bearing designs have changed significantly over the past decade. The original single-row ball/taper roller bearings have undergone three generations of evolution to cater for the advancement of automotive technology today.
Single Row Ball Bearing
Typical used in solid (driven) axle applications like the early Ford Transits and MG Midget. Thus, not commonly used now.
Single Row Taper Bearing
Used in non-driven axle applications such as Mercedes C-Class (front) and Volkswagen Polo (Rear).
Dual Row Angular Contact (DAC) Ball / Dual Row Taper Roller Bearing
Suitable for both driven and non-driven axle vehicles like Ford Ka and Volkswagen Golf.
Single Flange Hub
The bearing has either a wheel/drive flange or mounting flange integrated with a dual row ball/taper bearing. These are commonly found in the Audi A4 or Honda Civic.
Single Flange Hub
The drive flange is integrated with the inner race. It must be pressed in on the outer race (special tool required) and can be used with or without a locking ring. These are found in current models of Ford Focus, Volvo C30.
Double Flange Hub
The latest designs have either a double row ball/taper roller bearing and usually come with an ABS sensor built in. With a thicker flange, the races have different diameters or even different types of element (e.g. ball or roller). A larger outer race allows the fitment of more rolling elements to improve stiffness. The latest of the generation 3 hub reduces brake caliper ‘knock-back’ to improve braking performance. These are fitted in Vauxhall Insignias, Toyota Avensis and Ford Mondeos.
