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.

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.

• Reduced contact surfaces between hub and brake disc
• Conical ventilation channels in the brake disc
• Low heat transmission to the hub bearing

Since the brake shoes are mounted around a spherical head, uniform stress is applied to the brake linings allowing them to last longer.

SAF brake linings are asymmetrically shaped using computer calculations and are subjected to continuous strict production controls. Special material blends and the unusual shape pay off by giving long service life and best possible safety.

For the SAF drum brake you will need a screwdriver to change the brake shoe and a flick of the wrist – extremely simple and done in seconds.

The precisely machined S-cams can control the movement of the brake shoes and the contact pressure precisely, thus ensuring optimum braking action.

As a premounted unit without individual parts and thanks to its small dimensions it can be replaced quickly and easily when needed. It is permanently corrosion protected and only requires regular lubrication. You save time, money and weight.

You will not only save with warehousing but also and more particularly on the maintenance and repair.
