Need to replace 6" single inline roller omniwheels on a 2008 robot. Existing wheels have miles and miles of on-pavement travel and are just plain worn out. Dual inline will not fit. Anyone have a source for these (in 6"/150mm flavor)?

I found a discontinued Andymark product for sale from another vendor at this link that seems to fit the description of what you want.
Is it just the rollers that are worn out? If so, we sell replacement rollers here: http://www.andymark.com/Replacement-roller-set-for-6-omni-wheel-p/am-0240.htm
