Look at casters, both in swivel and non swivel versions.

If speed and accuracy requirements are modest see "ball transfers" --
the 2-axis version of what you've described. For example, McMaster
pages 1229 thru 1231.

Can you use ball transfers? They are spherical:

Look at parts for RC model race cars. Google "turnbuckle traxxas" for
a good variety of choices.

Hmm, The older Ford Escorts with the 1.9 engine use roller cam lifters.
I've got a pair floating around here somewhere but can't locate at the
moment. IIRC, they were around $16-18 each. A block with a bored hole,
side slot, and clamp screw would hold them. If your design offers axial
access, a separate adjustment screw and lock nut would allow adjustment
and prevent it from pushing away from any load.
Hope that explanation is clear...

--Gotcha; that's similar to what I had in mind: threaded shank with
height adjusting nut and shank in a holder that's bolted to the base. Holder
has setscrew to lock bearing holder in place.

yes, they're called a cam follower. They are available from bearing
suppliers. They are relativley cheap.
