Torque Limiters can be used to protect any machinery with rotating components. If there is any risk of a drive shaft transmitting too much torque to the driven shaft or tangential parts, a Torque Limiter can ensure torque never reaches critical levels. The components couple the two rotating bodies and introduce a disconnect method.
