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

The AC113 is a ball bearing rub collar — 3-inch outer diameter, 1-1/4-inch bore — for 1-1/4-inch bore shaper spindles. The 3-inch OD is a commonly used mid-range size in the Pro-Line shaper series, matching cutter stack diameters in a wide range of standard profile setups. The ball bearing design keeps the collar stationary against the guide surface while the cutter rotates. For the slightly larger 3-1/16-inch OD, see AC113A. For 2-3/4-inch OD, see AC112. For the range up to 125mm, see AC114 through AC125.
