Steel Arbor Spacer, 1-1/4″ Bore, 9/16″ Wide

Description

At 9/16″, this Pro-Line arbor spacer bridges the 1/2″ and 5/8″ positions in the 1-1/4″ bore spacer range. On the Pro-Line spindle, one 9/16″ piece instead of stacking a 1/2″ and a 1/16″ keeps the parts count low and minimizes the mating surfaces that contribute to tolerance stack-up under the higher loads Pro-Line tooling generates. The machined steel body features precision-ground parallel faces that seat flat against adjacent cutters and collars. Freeborn’s consistent bore tolerances across the full Pro-Line lineup ensure this spacer fits the 1-1/4″ spindle with the same close fit as every other width. A practical choice in any Pro-Line accessory kit that aims for minimum-part-count setups.
