They might be. Sometimes they tend to separate between the base and top,
especially if weight hang from the or are installed sidewise. If the turrets
are on top of things and the weight is at least somewhat balanced they should
be fine.
For extra super-duty turntables (as they are used in big cranes in .technic)
you can put a circle of rollers around the turntable to hold the weight and
just use the turntable element to turn the structure. This is probably overkill
in this application though.
See TJ's crane, under Thrust Roller Bearing:

There's plenty of examples of this. Ask in .technic if you need more info.
If you get problems with separation you might be able to find those threaded
technic axles and a couple of technic nuts to help secure things.
