3 inch Center Plate - For all 3 inch center buffing wheels
3 inch Metal Center Plate. This Center plate is 3 inches in diameter. You will need to tell us what size center hole you require for your needs. The center plate is the thin metal support plate mounted in the center of the buffing wheel. These center plates are to adapt the larger center hole of the buffing wheel down to the small diameter of the buffing machine shaft. They allow air to circulate during buffing and keep the wheels true on the shaft. Buffs are mounted on the buffing machine shaft with one center plate per buffing wheel with a pair of end flanges holding all the mounted buffing wheels together on the shaft. Unless you specify our airway buffs are sold with centerplates pre-mounted. You can buy center plates separately here if you need to.
