    Great Value

    This is a pretty awesome keyed wheel hub. You can tell it's been turned down on a lathe, not cast like the cheaper Chinese versions. Tolerances seem to be pretty tight for what it is. The one thing I don't like about this hub is that the bottom is not entirely flat. It has a small raised area on it so you can't mount something flush on the bottom. All of this is documented on the drawing and CAD model. Speaking of which, the CAD model and drawing is the reason I went with this hub, good documentation is hard to find on those Chinese websites. Overall, good value, good documentation. Nice work AndyMark!

    The hub worked perfectly. The shaft fit was super close and the key fit perfectly in the slot. Very pleased.

    hub is nicely machined and fits 8" wheel perfectly

    1/8" key fits perfectly but needed to drill and tap a 8/32 machine screw to lock hub on shaft to stop axial movement. Hub should come with this done already.

    8"Mecanum wheels

    Everything was A1 about the wheels except for 4 BENT roller wheel bolts.. these are hard to find in our area and NO EXTRA ( which is my suggestion ) bolts ,nuts, etc. 1 of each item, is only 4 pieces of hardware per wheel and considering the # of parts per wheel its less than 2% and would have saved us a half of day searching around for such a specialty bolt. AWESOME WHEEL NONE-THE-LESS. And LIZ was a great tech help BTW.

    AnyMark Hubs

    I find the hubs easy to use. The location of the holes is also easy to replicate on a milling machine, in case I need to mount the hubs to a plate, instead of an AndyMark Wheel.
