Sproket 8 Teeth 1/8 Bore

The self-lubricating acetal resin makes this sprocket run smoothly on my model train and I've had no issues with binding during operation. It was a direct fit for the 1/8 bore shaft and feels much more durable than the stock part.

I swapped out the old plastic sprocket on my model train for this acetal resin one—the self-lubricating action is noticeably smoother. It fits the 1/8 bore shaft perfectly without any wobble.

The self-lubricating resin keeps my robot's chain running smoothly without any added oil. These 8-tooth sprockets are tough enough for daily use and snapped right onto the 1/8 bore shaft. Exactly what my miniature mechanism needed.
