Torque Transmitted by Clutch Calculator

Torque Transmitted by Clutch Calculator calculates the maximum torque that can be transmitted by a clutch under uniform wear based on operating dry and running in oil coefficients of friction and lining pressures.

It calculates the maximum torque that can be transmitted by a clutch that is undergoing uniform wear. To use this calculator, enter value in empty boxes below then click on Calculate button to compute the maximum clutch torque.

  • For a clutch operating dry the coefficient of friction will normally be in the range of 0.2 – 0.45.
  • For clutches running in oil the coefficient of friction will typically be in the range 0.08 to 0.15.
  • Typical lining pressures are:
    • Moulded materials and sintered metals: 1 to 2
    • Cast iron: 0.7 to 1.7
    • Cork: 0.05 to 0.1

Note: Torques of less than 0.001 Nm will not be correctly displayed.
