1. High-Strength Ductile Iron Casting Technology
Integral sand casting with high-toughness ductile iron featuring fine uniform internal metallographic structure, superior tensile and fatigue resistance over ordinary gray cast iron. Triangular hollow reinforcing ribs reduce dead weight while boosting structural strength to avoid fracture under frequent braking and rough mine road conditions. Sand cleaning and deburring after casting, 100% flaw detection to eliminate air holes, sand holes and cracks.
2. CNC Precision Machining For Perfect Vehicle Fit
Camshaft inner bore, brake shoe fixing holes and axle flange positioning holes are fully CNC bored with mirror inner surface and tight tolerance control. Hole spacing and tilt angle fully comply with original JS16G01R dimensions, no grinding or reaming needed during repair replacement for fast assembly/disassembly. Smooth inner bore reduces camshaft abrasion, ensures smooth brake return and even friction pad wear without bias grinding.
3. Heavy-Duty Durability To Cut Maintenance Cost
Thickened flange transition resists torsion under huge impact from brake cam and shoes. Step sealing grooves inside & outside cooperate with oil seal to block mud, water and sand from entering bearing area and extend bearing service life. Full black anti-rust paint coating prevents corrosion for long-term outdoor and construction site use. Firmly supports full drum brake assembly for stable braking force and lower risk of brake failure.
4. Vehicle Compatibility & Supply Advantages
Fit all flatbed, dump, box and cargo semi-trailers equipped with FUWA 16-ton drum axles. Dedicated JS16G01R model for direct replacement of original old brake brackets. Mass self-production with abundant ready stock, stable supply for auto parts shops and logistics fleets, favorable bulk wholesale price, custom export packaging available.
