The tubes contacting the tire only rotate when raising the wheel. There are no bearing or bushings needed. The caster wheels support the weight well, and move the tires easily.

These are very nice sturdy wheel dolly. I use in my garage to move a 4700 lbs boat around the garage.
Yes the dolly has bushings in the tubes.

I believe they are bearings. Understand I have had these almost 3 yrs now and manufacture may have changed since then
