I dig it. (I could use these on a suitcase; certainly would've been nice for beating a path through dense train stations.)

Will these be available sans bearings?

[ATannahill]

May I ask why the spec for the width is just (outside face to outside face)?

Overall these look awesome. I would like a pair on my bowling bag. I look forward to seeing these on some robots.

This is a very nice addition to the AM line-up, Andy.

A few questions: are the rollers identical to those used on other AM omniwheels? How are the roller spindles retained in the black polycarbonate wheel plates? Are the wheel plate halves held together with adhesive?

Yes, these are the same black SBR rubber rollers used in the 6" and 8" omni wheels.

The rollers ride on a captured dowel pin.

The wheel plate halves are held together with 6 screws, so the rollers can be replaced.

Thanks for the questions,
Andy

In case anyone wondered the same question as me, it appears that they are also offered without bearings and in a single-wide form. The dualie form seems to be significantly cheaper than buying two singles with bearings ($46 vs. $58).
