Re: pic: Why aren't omni wheels like this used?

I definitely like this one better. At first, I was worried about the variable distance from the pin to the roller, but then I realized that this is also a problem with the DuraOmni, or any omni with fewer than a couple dozen rollers. I can easily imagine how to have the wheel be together, but how it comes together is certainly a challenge. Perhaps if you had some spacers that entered through the hub and held the two halves of the wheel frame apart equal to the pin diameter, laid it horizontal, then maneuvered each wheel/pin in, and finally removed the spacers and bolted the two halves together? To do this properly with minimal roller wobble, you'd probably have to have the top and bottom halves not be reflection images.


Ether, as to Duraomnis: We used them this year for what was originally an H/slide drive. They are shipped assembled, and dis-assembly was not something obvious. I'll try to remember to take a look at ours on Saturday to see how they go together and if I can confidently take one apart find out what they're made of. By "axial load", I take it that you mean load parallel the roller axis, or equivalently, thrust/braking along the wheel's canonical direction of travel. Please advise if this is incorrect.
