Sprocket 20 Teeth 1/8 Bore

This little sprocket fits perfectly on my model train’s drive shaft, and the self-lubricating acetal resin means no extra oiling is needed. It’s held up well through hours of running.

I was pleasantly surprised by how smoothly these sprockets run in my model train setup, the self-lubricating acetal resin really cuts down on maintenance. They mesh perfectly with the 1/8 bore and feel tough enough to handle continuous use.

Dropped these into my model train gearbox and the acetal resin slides so smoothly I forgot they were even there. The self-lubricating property is a real timesaver, no more greasing every session.
