I have that stick to and don’t worry, you’re fine. It feels like the ball will roll off but it won’t. It’s impossible to unscrew it from the top. You have to get a screwdriver and take it off from the bottom. Look at this picture. On the bottom you can see the place where the screwdriver goes. What you’re turning is a combination of the ball and stick shaft. Don’t confuse the stick shaft with the shaft cover, though. The shaft cover shouldn’t be an issue since you probably won’t hold it. The actual stick shaft (silver part underneath) also won’t screw off or mess up motions even if it spins. This is how most sticks work but you can just feel it more with Japanese sticks. You just have to get used to it.
If your stick doesn’t fit the description that I just outlined then it’s possible you actually might have a problem. If the stick spins when you don’t want it to or aren’t even trying then it sounds suspicious. The shaft cover spinning is certainly not an issue. But holding the stick firmly and moving it shouldn’t give you any spinning.
Hope that helps. Also, thanks to lizardlick for hosting the pics. If you don’t want me to link them, just let me know and I’ll remove them.

JLW-UM-8 has a thicker shaft and it can only hold 45mm balltops and battops, it can not hold 30mm and 35mm balltops.
JLW-TM-8 can use any (with adapter).
I will upload a video about Sanwa joysticks in a little while…
Discovered through the new HRAP2SA: as perthis observation (bad pun intended), it appears that Sanwa OBSF-24 K/DH now exists! (24mm snap-in buttons in the composite color black/grey)
