Flange Mounted Clutch Couplings - Type FOFlange Mounted Clutch Couplings – Type FO

FO series power-on clutch couplings are used to couple two in-line shafts. The armature hub assembly is mounted to the load shaft and the rotor assembly mounted on the input shaft. The field assembly is mounted to a bulkhead that is perpendicular to the shaft.
