Wheel hub 9906.003104015-10 is a semi-trailer axle component cast in VCh50 ductile iron per GOST 7293-85, with a 160 mm bearing seating diameter, 23 mm wheel bolt holes and a product height of 247 mm. The hub carries the wheel bearings and bolting of trailer axles — a part whose material grade is its quality story: VCh50 high-strength ductile iron delivers the fatigue and impact resistance that semi-trailer wheel ends demand under full loads, potholes and curb strikes, where lesser castings crack.
The GOST-referenced material specification gives buyers a documented standard to verify against, which matters in axle assembly and certified repair. Hubs turn over steadily in the aftermarket as bearings seize and seats wear beyond tolerance.
With a 20-piece minimum order at accessible pricing, the hub targets trailer manufacturers, axle assemblers and heavy parts distributors sourcing standard-documented castings directly from Russian foundry production.
