Brake Drum

This Brake Drum is a vital friction component in drum brake systems, widely used for reliable wheel braking control. Offered in standard heavy-duty and reinforced high-load types to adapt to different working scenarios, Brake Drum is produced from high-performance pearlitic gray cast iron with precise casting and heat treatment, delivering exceptional heat resistance, high thermal conductivity and uniform hardness distribution. It features strong resistance to cracking, deformation and heat fade during prolonged heavy braking, with a smooth friction surface that ensures stable braking efficiency and low noise. Common specifications include outer diameters ranging from 220mm to 410mm, depth from 80mm to 180mm, hardness between HB180–240, and maximum working temperature up to 600℃. The optimized structural design enhances overall rigidity and load-bearing capacity, while strict dimensional processing guarantees perfect matching with brake shoes. Every unit passes dynamic balance, wear resistance and fatigue tests in line with international automotive standards. Brake Drum provides stable and safe braking output, reduces maintenance frequency and performs reliably under long-haul .
