Ogura electromagnetic clutches can handle the torque and speed requirements of most small to midsize gas and diesel engines up to around 40 hp. Clutches can handle engine shaft sizes 1", 1 1/8", 1 1/4" and 1 7/16". Since clutches are made to mount right onto an engine shaft, they can take the vibration and temperature from small gas or diesel engines. Clutches can then either drive customer's components directly or through a belt. A variety of pulleys already exist, however, customer designs are also possible.
