Sproket 10 Teeth 1/8 Bore

The self-lubricating acetal resin is a nice touch—my model train runs quieter and smoother than with the old metal gear, and the 1/8 bore fit perfectly on the shaft without any filing. Solid little part for the price, I'll be ordering more for my next robotics project.

Replaced the old plastic sprocket on my robot arm with this acetal resin one and the movement is finally smooth and consistent. The self-lubricating feature is a real bonus for a tinkerer like me.

My son’s model train kept slipping on the old gear, but this one’s self-lubricating acetal resin makes it run smooth and silent. The 10 teeth mesh perfectly with the chain we had, and it hasn’t loosened after hours of use.
