Webb Wheel says Vortex Unlimited, manufactured in the U.S., has been designed to be durable and to run cooler because of improved heat transfer efficiency. On the drive and trailer axle configurations that include Webb’s patent-pending wear indicator, vehicle operators can expect 25 percent more life from the Vortex Unlimited, the company says.
A center squealer band strengthens the Vortex Unlimited and cast-in exterior ribs conduct heat away from the brake surface, which Webb Wheel says results in 10 percent lower operating temperatures. Webb Wheel also says dynamometer testing shows the heat generated by the Vortex Unlimited during a braking event is significantly less than with a standard brake drum. Running with lower temperatures extends drum and lining life, and increases stopping performance, the company says.
Vortex Unlimited drums now are available in five sizes and can be used as a replacement for standard-duty cast brake drum applications.
