The MC electromagnetic clutch line now uses two ball bearings instead of bushings. The bearings, located under the field assembly, allow the clutch to operate at 3,600 rpm. A zerobacklash single-spring armature design prevents armature rattle for quiet operation. The clutches come in a 4.5 and 9-lb-in. torque rating. The RoHScompliant clutches conform to UL/ CSA requirements for the lead wires. Ogura Industrial Corp., Box 5790,
