Hi Kieth,
                 The specifications call for Darnell castors, from time to 
time there has been substitutes for what ever reason.  I assume it was 
penny pinching. and they gave problems.
The spec's also call for a force fit.  Things go wrong in the plant, and  I 
have seen times when little short screws were used, and that also lead to 
problems.
I would agree that the Hamilon's (45" studio piano) have not had so many 
problems with castors.

As for Hamilton's, we have been selling about 40 a year (on average) for 
the last 30yrs, so I think I have you beat for numbers dept. Where they are 
rolled over surfaces that go from solid to carpet, that is where the 
problems start.   Those carpet cleats play havoc with them. But to be fair, 
I don't think any caste r mount,will stand that for long.
Regards Roger
