[TowerTalk] Rotor Stripping Gears?

I learned it twice that worm-gear drive rotators also loose their gears.
Two of my Prosistel PST2051 failed with a beam of 0,9m² at 10m height and
only 60km/h wind gusts at that time.
The worm axle pushed the bearing completely out of the housing which ruined
the worm wheel immediately.
I was quite happy it happened during the warranty period and it was repaired

without any problem by the factory, but I still do not believe that those
rotators are good for 2,5m² of windload as claimed, so I use them for real
small antennas only since then

        This sounds like a typical  Hy-Gain rotator failure. Is that right? 
With the current worm-gear drive  rotators (e.g. Orion, BigBoy, AlfaSpid), 
won't suffer the same fate.
