Application
For heavy - duty trucks, buses, and construction vehicles, hub units are designed for extreme durability and load capacity. They withstand massive radial/axial loads from heavy payloads, frequent starts/stops, and rough terrains. Reinforced bearings, thickened flanges, and advanced sealing resist impact, dust, and water ingress. They also handle repeated braking torque, ensuring consistent performance during long - distance transportation and harsh - environment operations.
