28 Tooth 20 DP 0.75 in. Hex Bore Steel Gear

Introducing FlexHub, designed by engineers from iR3 Creative Engineering, from Orlando, Florida. FlexHub is a modular gear & hub solution from iR3 Creative. The concept is pretty simple. There is a hub, there is a gear, there are two retaining rings. Put them together into your assembly. If the gear ratio / shaft size / output / whatever isn’t working rinse and repeat with a new hub or gear. Check out the FlexHub Flyer
