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.

NOTE: Some of these hubs feature an unneeded key way. These are not needed and will not hinder performance of the hub.

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.

Nubs are hubs intended to connect motion components to spinning shafts, like sprockets gears, pulleys and wheels. This Nub features a round boss on both sides with a 5 mm hex bore in the middle. This bore allows for pairing of REV 5mm hex components with other motion parts that interface with Nubs.

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 once they are driven in the first time.

Specifications:

• Length: 0.630 in. (16 mm)
• Height: 0.630 in. (16 mm)
• Material: 6061-T6
• Bore: 5 mm Hex
• Overall Depth: 0.866 in. (22 mm)
• Set Screw: Holes sized for 10-32 Set Screw (Set Screw Included)

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.

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.
