NICHOLSON 27" Air Seal Debarker Rings - Rings only with carriers, not complete debarker. These were run a short period of time and replaced with larger rings. Carriers fit only model A8 debarkers but rings fit most or maybe all Nicholson models of the same ring size. Each has a 125 HP, 1200 rpm electric motor. One carrier fits a left hand machine, other fits a right hand machine. Rings will fit either hand and are standard rotation.
