Sprag Clutch Applications

Industrial Winch

A winch reliably works to provide critical safety and support. A sprag clutch inside a winch helps lock the winch cable into place in an event of a motor failure.

Automatic Transmissions

Automobile transmissions need a clutch to engage and disengage gears. Using a sprag clutch is ideal because it allows the gears to smoothly transition under medium to heavy loads.

Torque Converter

A torque converter efficiently transfers an engine’s rotation to the transmission via the transmission fluid (also known as a fluid flywheel or fluid coupling). And a sprag clutch plays a big role in ensuring a torque converter works properly.

Helicopter Rotors

The rotor on a helicopter is one of its most important parts because it allows the helicopter to take off and move in different directions via airfoils. If an engine failure occurs, it is critical that these airfoils are able to rotate. A freewheeling unit makes this possible.
