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.
