Clutch Torque Capacity Calculator

Torque the clutch must hold.
lbf·ft
Pressure plate clamp force.
lbf
Effective clutch lining coefficient.
Mean radius of the friction ring.
in
Single-disc clutch usually has two friction interfaces.
Capacity divided by this factor for design comparison.

  • Uses a simple uniform-wear mean-radius torque model.
  • Real clutch holding torque depends on lining material, temperature, pressure distribution, break-in, flywheel condition, release travel and dynamic shock loads.
