Description
The AC116A is a ball bearing rub collar — 3-7/8-inch outer diameter, 1-inch bore — for 1-inch bore shaper spindles. The 1-inch bore distinguishes this collar from the adjacent 1-1/4-inch bore models (AC116, AC117): the AC116A is used on machines with 1-inch spindles requiring a large-diameter rub collar for wide cutter stack operations. Ball bearing design for stationary contact against the guide surface. Confirm spindle bore before ordering — the 1-inch bore is not interchangeable with the 1-1/4-inch bore series. For 1-1/4-inch bore at 3-3/4-inch OD, see AC116.
