Plastic Sprockets
Bore Tolerance: +.002/ -.000
Now it is easier than ever to design your project with metal or plastic chain. Our plastic hub sprockets are not only extremely strong but lightweight as well. The sprockets are 0.100” thick, accept standard 0.25” (1/4”) metal or plastic chain, and work well with our 0.770” aluminum hubs.
