You're saying I need some of these on here, and to switch from pivoting on the mecanum wheel, to pivoting on the traction wheels I choose? http://www.andymark.com/product-p/am-2345.htm Or would I be able to just use ball bearings as the person above said

And how should I strengthen it? Should I make the actuators thicker? I realize I need a support between the two wheels, and I have yet to the shaft size on the traction wheel to 1/2", but how would you recommend strengthening it?

And also, I never mentioned that this will be encompassed in a module, so it will have a casing around it so that the CIM and pneumatic cylinder can be mounted on it, and the module would then be mounted with springs so as to make the mecanums sit level.

The traction wheels are also not meant for "constant use" I have them geared down to 5 fps, so that they are for pushing, whereas I can have the mecanums at 15 fps for cruising
