PTO electromagnetic clutch 1,voltage:12VDC 2,power:60W 3,torque:200N.m 4,allowable speed:5000rpm A one piece solid forged rotor means no chance of internal parts separation. Our rotors also have an even wall thickness around the coil which gives optimum flux distribution, maximizing torque. Although 12 volt is the most common, 24 volts can also be made available. Depending upon the quantity, other specialty voltages can be made. All models include our special long life grease which has shown a significant improvement in life over other standard high temp greases.
