Hand Fine Gear for Polar Paper Cutter, 218629, G321
- Our Part Number: G321
Hand Fine Spur Gear (equivalent to Polar 218629). This 22 tooth gear is used in the hand fine adjustment mechanism on many of the early Polar EL and Polar CE model paper cutters.
The teeth are curved round "lobes", not conventional gear teeth.
This gear does not fit on the Polar 72 models. The Polar 72 cutters used a smaller 12 tooth gear, Polar part number 218631, our part number G319.
It's outside diameter measures 4.97" (126mm). Its overall width is approximately 1.57" (40mm). It has a 19mm diameter bore (.75"), and a 6 mm wide keyway. This gear is machined from Delrin plastic and it mates with our pinion gear, our part number G320.
