Re: where to buy mecanum wheels?

The 2008 ones had a different strength than the 2009 ones IIRC. I remember there being surveys done asking teams who used the wheels in 08 (including us) what our thoughts were and the biggest suggestion was improve the strength of the side plates and I believe this was done for the new year. Either way, I trust AndyMark, they don't build inferior products.

Re: where to buy mecanum wheels?

I'd look at the shape of the wheels too.

The steel wheels on my 4000 lb truck are three times as thick as the AM wheels

In 2007 we used the 8" version. Those are built like tanks...we've never bent one. Of course they are much heavier. Those you'll need to reduce the speed using chains from a 12:1 transmission.
Ok, thanks. We're planning on using the 8" ones also. And we really can't run them direct drive off the BaneBots transmission?

I like to put my trust in AndyMark too, but I was dissapointed in the performance of their 6" aluminum omni wheels we used for Overdrive. First round on the field they bent in half like they were paper, and we weren't even hit that hard. So now our lead mentor is very cautious about purchasing their parts and I had to spend 2 hours yesterday convincing him that AnyMark is pretty much the only place to buy mecanums.

We're planning on adding an aluminum plate to the outside of the wheels to protect those "fins" that hold the rollers.

We have spent the last four years running exclusively on AM wheels and transmissions. In those 4 years we have only encountered one problem and that issue was quickly resolved by AM.

This will be year number 5 of us rolling around on AM. We are very happy about their quality and support.

Oh, I completley agree. In fact, Im going to show him this thread as proof The kit frame has been outstanding the past two years, and their plastic kit wheels, hubs and sprockets have been excellent too. In the past we've also used their gen1 shifter transmissions, which are beast. And their great on order placment to ship time too.
