3-1/2” OD x 1-1/4” Bore Ball Bearing Rub Collar

The AC115 is a ball bearing rub collar — 3-1/2-inch outer diameter, 1-1/4-inch bore — for 1-1/4-inch bore shaper spindles. The 3-1/2-inch OD accommodates large-diameter Pro-Line cutter stacks in panel raising, large-profile moulding, and template-routing operations where the cutter radius is substantial and the guide collar must match. Ball bearing design keeps the collar stationary at guide contact while the cutter rotates. For smaller OD, see AC114 (3-1/4-inch). For 3-3/4-inch and larger, see AC116 through AC125.
