This heavy-duty brake drum is cast from premium grey cast iron. The thickened solid structure delivers outstanding mechanical strength, resisting thermal cracking and wear under long-time heavy-load braking. Precision inner bore machining guarantees smooth friction surface and stable braking output. It is widely used for heavy trucks, semi-trailers and other commercial transport vehicles. We support production according to OE numbers, drawings or physical samples.

FAQ
Q: What is solid cast iron heavy duty brake drum for commercial vehicle trailer axle used for?
A: It is a core drum brake component for commercial vehicles and trailers. It cooperates with brake shoes to generate friction force to slow down and stop heavy vehicles.
Q: What are the advantages of this thick solid brake drum?
A: The thickened structure has higher heat capacity, it is not easy to crack and deform under continuous heavy braking, suitable for overland heavy transport.
Q: How long is the service life of this brake drum?
A: Service life depends on load, road condition and braking frequency. Replace it once reaching the wear limit or with cracks.
Q: Can you supply matching brake shoes and wheel hub accessories?
A: Yes, we can provide matched brake shoes, wheel studs, lug nuts and other axle spare parts.
Q: Can you produce according to our OE number or sample?
A: Yes, we accept custom manufacturing based on your OE number, drawing or sample.
