This front wheel hub is a core load-bearing rotating component of FAW J6 heavy truck front axle. It supports the wheel, tire and brake assembly, and rotates together with the wheel during vehicle operation. It is precisely machined from high-strength cast alloy, featuring excellent rigidity and fatigue resistance under heavy load and impact on long-haul roads. Precision bearing mounting bore ensures good fit with wheel hub bearings to reduce bearing wear and heat generation. Every wheel hub undergoes dimensional inspection, ultrasonic flaw detection and balance test before delivery. It solves problems such as hub deformation, bearing bore wear and abnormal wheel shaking, serving as an essential replacement spare part for heavy truck front axle maintenance.
