Kenworth Truck Co. has announced availability of aluminum hubs as a front and rear axle option on Kenworth Class 8 trucks and tractors equipped with Bendix ADB22X air disc brakes.
The new option offers lower operating costs to on-highway and vocational customers that demand weight saving components and are interested in an efficient braking package. The aluminum hubs are much lighter, with almost 80 lbs. of weight reduction per axle compared to traditional iron hubs. Enhanced heat rejection dissipation and increased brake pad life are added benefits of splined rotors paired with aluminum hubs, the company says.
The aluminum hubs are available with front Bendix ADB22X air disc brakes equipped with Dana Spicer steer axles up to 14,600 lbs. For rear applications the aluminum hubs are available with Bendix ADB22X air disc brakes equipped with Dana Spicer rear axles up to 23,000 lbs. (single), 46,000 lbs. (dual) and 69,000 lbs. (tridem).
The Bendix ADB22X air disc brake model features a mono-block caliper design that provides a compact brake compared to two-piece caliper models. This design offers sealing that provides optimal protection from environmental elements, the maker says, and a larger rotor that absorbs more energy.
Extensive product testing conducted by Bendix Spicer Foundation Brakes has proven that Bendix-brand air disc brakes virtually eliminate brake fade with no degradation of stopping power, enable a passenger car-like feel, and, in controlled tests, permit straight, stable stops due to high brake efficiency and low hysteresis. Bendix-brand air disc brakes are compatible in a variety of combinations with North American tractor and trailer air drum foundation brakes.
