Product Information
Model 0310677630 brake drum is a core braking component for heavy-duty trucks and semi-trailers. Crafted from high-strength HT250 gray iron and subjected to strict heat treatment and precision machining, it features uniform hardness on the braking surface and excellent thermal fatigue resistance, ensuring stable braking performance under extreme conditions such as heavy loads and frequent braking.
With a 420mm braking surface diameter, 290mm inner diameter, 10×Φ23mm fixing bolt holes, 335mm bolt circle diameter, 290mm center pilot hole diameter, and an overall height of 296mm, it fits perfectly with BPW axle systems for direct replacement installation. Each drum undergoes dynamic balance testing, full dimensional inspection, and pressure testing before shipment to effectively prevent braking vibration, cracking, and leakage risks, enhancing driving safety.
The surface is anti-rust treated for strong corrosion resistance and long service life. Suitable for the rear axle braking systems of heavy-duty trucks, engineering vehicles, and semi-trailers, it is a high-cost-performance choice for maintenance and export. Custom packaging and brand marking are available for bulk orders, with a 12-month warranty period.
