VersaHubs (7 Choices)

If chain is being run on two sprockets of the same shaft (such as you would find in the center shaft of a 6-wheel drive), care must be taken to ensure proper chain clearance. For #25 chain, a 1/4" Sprocket Mount VersaHub can be used to achieve a compact package if the two master links are mounted on the "outside" of the chain run. For #35 chain, a 1/2" Sprocket Mount VersaHub is an ideal solution regardless of master link orientation.

Since VersaKeys efficiently transfer torque while perfectly piloting gears or other hardware, VersaHubs can even be used to manipulate larger VersaFrame mechanisms. The VersaBlock includes a female VersaKey pattern which interfaces with driven rotary motion (such as a sprocket and chain) through a Sprocket Mount VersaHub. This technique was used in Team Copioli’s 2014 Build Blitz Robot and in the 2015 Build Blitz Simple Stacker.

Since the 1/4" and 1/2" Sprocket Mount VersaHubs feature both male and female VersaKeys on all sides, they can be used as spacers or to create a rotating drum between two other VersaKey products. Team Copioli's 2014 Build Blitz robot utilized this feature on its intake roller.

While 1/2" hex is quickly becoming a common standard in competition robotics, we understand that many teams still use other axle options such as keyed shaft or other hex sizes. The 1/4” Round Bore VersaHub is designed with those teams in mind – simply broach, bore, or drill the center hole to your desired size and enjoy the advantages of the VersaKey system.
