Duo Expert …tolerance free wheel centring
HAWEKA's tolerance free expanding collet system. The patented expanding collet system by HAWEKA has enabled 'tolerance free' balancing for hub (centre bore) located wheels.
Why is this important?
Most of the vehicle manufacturer's wheels today are hub located. This means the wheel fits tightly over a machined hub and the wheel nuts provide the even torque to insure that the wheel is at 90 degrees to the hub.
The Duo Expert system allows the after-market to replicate this and therefore achieve the same balance results as the vehicle manufacturer.
How does this work?
The Duo Expert collet is cylindrical just like the hub of a vehicle. It therefore takes full advantage of how the wheel and the vehicle hub are manufactured. When fully clamped on the wheel balancer the Duo Expert has zero tolerance between the wheel centre hole and outer segments. The Duo Expert collets are used instead of cones and are recommended by many vehicle manufacturers and made mandatory by others like Mercedes-Benz, BMW, Porsche and more.
