VersaHubs

VEXpro VersaHubs provide frustration-free torque transfer between wheels, gears, sprockets, and shafts.

Got a 1/2" Hex that you need to put a plate sprocket on? No problem. Need to mount a 64-tooth gear to your Mecanum Wheel? We can do that. Whatever your need, these hubs will help you integrate everything together seamlessly.

Most of the wheels and sprockets that teams typically use (including the previous generation of VEXpro wheels) don't take piloting into account. We wanted to make sure that everything pilots correctly... every time. Wheels, hubs, gears, sprockets… they all work together.

VersaHubs include the innovative VersaKey mounting system -- VersaKeys transfer torque between coaxial items, and also ensure everything is piloted correctly.

About VersaHubs & VersaKeys

All VEXpro Versa products have the innovative VersaKey mounting system with holes that makes it easy to mount wheels to sprockets, gears, shafts, and bearings. The patterns pilots items together without relying on screws. There are 6x 8-32 screws on a standard 1.875” bolt circle. There are 3x male and female keys on each side that transfer torque and pilot items together.


VersaHubs

VersaHubs are available for sprockets, ½ hex, and ½ round. VersaHub for sprockets have a flush mount hole for 1.125” OD bearings.

Assembly Example


VEXpro wheels have the VersaKey pattern on both sides.
VersaHubs provide space between the wheel and sprocket, align the sprocket, and transfer torque.
1.125” OD bearings flush mount in the hub and wheel.
Bearing #1 is retained with 3x 8-32 screws into the wheel.
Bearing #2 is retained by the hub and sprocket.
