Torque Transmitted by Clutch: Calculator
This 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.

The following numbers can be used for ZOOM Performance Clutch Products:

Stock Organic Facing Material = 0.25

Stage 1 ZOOM (Carbon/Kevlar Material) = 0.28

Stage 2 ZOOM (Kevlar Material) = 0.36

Stage 3 ZOOM (Ceramic Material) = 0.38

Stage 4 ZOOM (Steel Material) = .40

Single Disc Clutches = 2 Friction Surfaces
Dual Disc Clutches = 4 Friction Surfaces etc...
