Clutch Torque Calculator

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 more information on calculating clutch torque capacity - CLICK HERE.

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: Stock Organic Facing Material = 0.25 Carbon/Kevlar Material = 0.28 Kevlar Material = 0.36 Ceramic Material = 0.38 Steel Material = .40 Single Disc Clutches = 2 Friction Surfaces Dual Disc Clutches = 4 Friction Surfaces etc...

Clutch plate outer diameter: inches Clutch plate inner diameter: inches Coefficient of friction: Clamp Load (lbs): lbs Number of friction surfaces: (Single Disc = 2 Surfaces) Answer:   Maximum clutch torque lbf
