Hunt Boston Electric Pencil Sharpener Model 18 and 19 replacement plastic helical gear 70 teeth.Also fit X-acto 18xx and 19xx series sharpeners
This fine Nylon gear has improved design 6mm wide face for better durability and performance
Our gear is 20% thicker compare to OEM and other replacements
It fit snugly and won't slip of the shaft thanks to fine tuned center hole
configuration and 15 degree Helical teeth angle
Made out of Nylon - tough and flexible plastic
Nylon naturally slippery, no lubrication on gear teeth required!
We recommend 1 drop of machine oil on to the cutter shaft though.
Only Nylons should be used for gears where a slippery surface is desired.
All other materials (PLA, ABS, PET, etc.) will grind creating a plastic dust and eventually fail!
For details, please review all pictures, or you can find installation videos on
Youtube
We subsidize shipping cost
Do not waste your money on ABS or PLA plastic gear that may strip or even melt!
