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

Description

The AC112 is a ball bearing rub collar — 2-3/4-inch outer diameter, 1-1/4-inch bore — for 1-1/4-inch bore shaper spindles. The 2-3/4-inch OD is a mid-range size in the Pro-Line rub collar series, used where the shaper cutter stack diameter and the required cutting depth offset call for a 2-3/4-inch guide collar. The precision ball bearing allows the collar to track the fence, starting pin, or template guide without rotating with the spindle. For smaller OD, see AC111 (2-1/2-inch). For larger OD, see AC113 (3-inch) through AC125 (125mm).
