Webb Wheel has introduced the Vortex Unlimited, a cast brake drum now available for the most popular steer, drive and trailer axle applications. Made in the U.S., it was designed to be durable and to run cooler, the company says, by way of improved heat-transfer efficiency. On the drive and trailer axle configurations that include Webb’s patent-pending wear indicator, we’re told that truck operators can expect 25% more life from the new drum.
The Vortex Unlimited features a center ‘squealer’ band for strength and cast-in exterior ribs conduct heat away from the brake surface, said to result in 10% lower operating temperatures. Dynamometer testing clearly shows that the heat generated by the new drum during a braking event is significantly less than with a standard type, says Webb. Running with lower temperatures extends drum and lining life, and increases stopping performance.
Vortex Unlimited drums are now available in 15 x 4, 16.5 x 5, 16.5 x 7, 16.5 x 8 and 16.5 x 8.625 sizes from Webb distributors and can be used as a replacement for standard-duty cast brake drum applications.
