This clutch disc is 11 inch with 13 spline, 5 pads . Hub size is 28*21.5mm.,material is copper based. Existing tractor main clutch discs are widely used copper based friction materials , which have good wear resistance, large friction force during braking, and small loss to the hub. High-quality bronze sintered brake pads are made of advanced friction material copper-based metal and sintered at high temperature. High temperature resistance 600-700 ℃, strong wear resistance, good thermal conductivity, smooth frictional engagement, and long service life，it can play an instant braking effect in any environment and temperature. So this material is widely used for agricultural machinery clutches, such as tractors.
