Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

What makes the 87369 brake drum superior to standard cast iron drums?

Unlike standard drums, the 87369 brake drum uses a refined G3000 alloy and a secondary stress-relief process to eliminate internal tension, preventing warping at high temperatures.

How is the balance of the brake drum verified?

Each unit undergoes a dynamic balance test on high-speed rotating rigs to ensure concentricity within 0.02mm, eliminating vehicle shudder.

Do you provide custom dimensions for non-standard equipment?

Yes, our CNC facility allows for rapid prototyping and custom casting to meet specific engineering requirements beyond the 87369 standard.

What is the expected lifespan of the 87369 series?

Under standard heavy-duty cycles, the drum typically lasts 80,000km to 120,000km depending on shoe material and braking frequency.

How do you ensure corrosion resistance for maritime shipping?

We apply an industrial-grade zinc-phosphate coating and use vacuum-sealed moisture-barrier packaging for all export units.

What is the typical lead time for bulk orders?

Standard bulk orders are typically fulfilled within 21 to 30 days, depending on the volume and specific coating requirements.
