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 Nicholson machines. Each has a 150 HP electric motor. One carrier fits a left hand machine, other fits a right hand machine. Rings will fit either hand and are standard rotation.
