The P89 accommodates up to 2-inch offset wheels for application and maintenance flexibility, allowing fleets to choose the wheel end offset desired, and can accommodate both industry-standard single wide-based wheels with up to 2-inch offsets and dual wheel configurations.
The P89 hub design incorporates the Integral bi-metallic rotor, and uses premium matched-set bearings, which can be replaced with standard bearings for field service. It provides an industry-standard premium spindle nut with right-hand threads.
The Integral disc brake’s advanced rotor and hub adapter design provides advanced braking efficiencies, reliability, and low cost of ownership, and the rotor is designed with a series of ventilation channels to redirect and control high temperatures associated with vehicle braking, the company says. The Integral rotor expands in a radial direction maintaining a flat and stable braking surface, which significantly reduces harmful stress cracks and premature brake pad failure.
