The core of this new technology is the patented INTEGRAL-DISC. Compared to the conventional brake discs that are cast as one piece, the INTEGRAL is a compound casting of two materials into one unit. Therefore, it can expand radially under the effect of heat during braking, and then radially retract again when cooling after operation. Specifically that means: the INTEGRAL does not distort into the umbrella shape under the effect of heat, thus eliminating the dreaded hot spots that result in stress cracking and eventual failure found in conventional brake discs. Since the brake surfaces also remain absolutely flat in all operating states, the service life of the disc itself as well as the pads is also significantly prolonged.

Clearly reduced heat transfer due to small contact surfaces of the INTEGRAL-DISC and wheel flange.

Conical ventilation channels in the brake disc provide for optimum internal ventilation. Additionally: 10 ventilation channels under the brake disc and 10 additional ventilation channels under the adapter ring.

The INTEGRAL exhibits 100% more heat dissipating surface compared to a conventional design with one-piece brake disc and closed wheel flange.

With 15 large radiator-type ventilation slots in the wheel flange we achieve at least 60 % more ventilation cross sections than in a design with closed wheel flange – depending on the size of the openings in the mounted wheels.

A reliable product that has been proven more than 100,000 over: The hub-unit is a compact assembly of hub and bearing. It is adjusted at the factory and then encapsulated. The hub-unit is maintenance-free.

Exciter ring and sensor holder are premounted at the factory.

We use great care in long-term corrosion protection on particularly exposed parts, such as hubs, hub caps or screw connections as well as wheel bolts and nuts.

Standard features include: uniform bearings, ABV-preparation, integrated rim system, specific weight reduction, cathodic dip coating process of axle and wheel hub.
