The nub is a series of hubs intended to connect motion components to spinning shafts, like sprockets gears, pulleys and wheels. It supports the output shaft of the AndyMark NeveRest motors as well as the other motors on the market. It supports the AndyMark 6mm D shafts for robust motion systems and impeccable torque transfer. The four mounting holes on these nubs are sized at 0.128" diameter, with the intention of accepting a #6-32 threaded screw. They are not tapped, but can be tapped by most machine screws due to this diameter.

This is the "500EX Hex Hub" the bore is a 1/2" Hex Hole. It is a slightly different version of the 500 Hex Hub. It is manufactured differently, as it is extruded. Also, there is a 1.124" diameter boss on each side of the hub flange, providing a location for 1.125" bore flat sprockets. Are you having a hard time keeping your sprocket concentric with your hub? This hub is the trick.

This is the hub featured in the 2014 and 2015 Kit of Parts Drive Chassis and fits all AndyMark wheels. 

Specifications:

• Material: 6063 Aluminum
• Bore: 1/2" Hex
• Bolt Pattern: 0.204" diameter holes, evenly spaced on a 1.875" diameter bolt circle
• Outside diameter: 2.25"
• Weight: .088

This is the "500EX Key Hub". It is a slightly different version of the 500 Key Hub. It is manufactured differently, as it is extruded. Also, there is a 1.124" diameter boss on each side of the hub flange, providing a location for 1.125" bore flat sprockets. Are you having a hard time keeping your sprocket concentric with your hub? This hub is the trick.

The bore is a 1/2" hole with two 1/8" keyways. Only one keyway is needed to drive most wheels, so the second one is extra.

This hub fits all AndyMark wheels.

Also, the keyways are consistently aligned with the mounting holes.

Specifications:

• Material: 6063 Aluminum
• Bore: 0.502-508" diameter bore, with 1/8" keyway (2)
• Bolt Pattern: 0.204" diameter holes, evenly spaced on a 1.875" diameter bolt circle
• Outside diameter: 2.25"
• Weight: 0.1 pound

Upgrades to Nubs:
We are making improvements to the entire Nub line, including moving from the original machined design to one that is extruded and accepts screws more easily. Both kinds of Nubs will work fine, and you'll see the new-style Nubs (which you can identify by the open gaps between the screw holes and the edge of the Nub) as we exhaust supplies of the original Nubs.

These hubs high-strength aluminum Hubs are designed for competition robots.

Every hub still maintains a closed-profile hole for maximum strength. Every shaft hub has been designed with bearing bosses on both sides that have been sized appropriately for the mating bearings that would pair with the bore through the hub, which means you can run each hub right against a bearing with no need for extra spacers. All of these hubs are also made from 7075-T6 aluminum, which is much stronger than the previously used 6061-T6, 6005, and 6105 alloys from our older designs. Where possible, the shoulder on shaft hubs was reduced to 7/8 in. in diameter for an easier fit with our molded plastic wheels, while still maintaining a precise 1.125 in. diameter boss for locating in wheels, sprockets, gears, and more.

The holes are evenly spaced on a 1.875 in. circle and 0.201 inches in diameter. Hexes are timed to the holes, but keyways are not.
