Application
 
  • <p>Electric drive surface mining haulage trucks, earth-moving equipment, mining equipment, industrial equipment.</p>
 

Formulas
 

Torque (lb-in) = K x Pressure (psi) x Disc Friction Radius (in)

Torque (N-m) = K x Pressure (bars) x Disc Friction Radius (mm)

Friction Radius (in) = [Disc Diameter (in)/2] - 2.18 in

Friction Radius (mm) =[Disc Diameter (mm)/2] - 55.4 mm
