3-3/4” OD x 1-1/4” Bore Ball Bearing Rub Collar

The AC116 is a ball bearing rub collar — 3-3/4-inch outer diameter, 1-1/4-inch bore — for 1-1/4-inch bore shaper spindles. At 3-3/4 inches, this collar is in the large-diameter portion of the 1-1/4-inch bore rub collar range — used with the wider Pro-Line cutter stacks for operations like wide raised panel cuts, large-radius ogee profiles, and template routing where the cutter diameter is proportionally large. Ball bearing design maintains a stationary guide surface. For 3-1/2-inch OD, see AC115. For the 3-7/8-inch OD in 1-inch bore, see AC116A. For 4-inch OD with weight-relief, see AC117.
