This trailer brake drum is manufactured from high-grade cast iron. The outer cooling groove design improves heat dissipation efficiency during continuous braking, effectively reducing thermal expansion, thermal cracking and premature wear. Precision boring and dynamic balance control ensure stable braking, low vibration and long service life. It is widely matched with semi-trailer axles, heavy-duty lorries and commercial transport vehicles. We support production according to OE numbers, drawings or samples.
- High strength grey cast iron material

FAQ
Q: What is cast iron cooling groove brake drum for semi trailer axle used for? A: It is a key drum brake component for semi-trailer axles. It works with brake linings to create friction to slow and stop the trailer.
Q: What is the function of the outer cooling grooves?
A: Cooling grooves increase the surface area to release heat faster, protecting the brake drum from overheating and thermal cracks.
Q: Can you match brake linings and wheel hub parts?
A: Yes, we can supply brake shoes, wheel studs, hub nuts and other axle spare parts together.
Q: What is the surface finish?
A: Anti-rust black coating, the mounting flange is machined raw metal.
Q: Do you accept custom sizes?
A: Yes, we can produce based on your samples, drawings or OE references.
