16 Tooth 20 DP 10 mm Round Bore Steel Gear

excellent product excellent price great shipping cost & time I will bay again

great product great price great company yes I will buy again

I can use this with confidence of durability. Nice part

Note the am-1249 4mm key is not quite the right size for this gear and the PG motors. The Key needs to be taller (~5mm). With the right key I think this would be a good gear, but the am-1249 will loosen up and fall out if not held captive. Even with the key being held captive we found that the gear/shaft interface would get sloppy with use.
