Here's the breakdown :
A bearing is used so the other side of the piece with the o-ring rotates with the flex (preventing o-ring wear):

The o-ring side :

Also has a lube port, and the retainer ring set-screws to the flex to hold all three pieces together and as a byproduct it retains the flex if it comes loose from the collet
Rather clever !!

Where is my buddy Jimmy when I need'm... (inside joke)
That system is very dependent that you don't have a collet with horrible run-out (or misalignment for that matter)! Otherwise it's going to translate all of the misalignment into the stuffing tube, shaking the dog poo out of the stuffing tube/rest of the hull.

Don't get me started on runout lol.
I like it...there is a .187 version also

I was thinking about trying one but I wasn't sure if it was extra drag. If not I'll put on on all my boats. Anyone know if it's more drag?

Since the o-ring does not stand still with the flex rotating inside of it (see post #2)- it rotates with the flex, the only "drag" is that of the ball bearing. The only downside I can potentially see is that the retaining ring setscrews to the flex and has to be loosened to pull/lube the flex each time.

I got a mess of these in and they sold out very quickly. I'm waiting for more. My experience with them says;
1. I found its much better with a 50/50 mixture of ATF and a heavy oil like STP between runs. I don't like putting actual lithium grease through it. (Or any other oiler I've ever used)
2. I found they work best with a clamp on collet as opposed to a floating square drive like I use in my nitro 1/8 scale. If you use on a square drive the cable clamp moves slightly as the cable floats. I don't like that.
Remy put a lot of thought into these and I think he found a winner.

If it would work with grease I'd jump on it. Perhaps you could squeeze it in while you rev the prop a bit to let the shaft work it down into the tube. I put a stuffing tube bracket with an oiler/reservior setup in my Sniper, and I don't use it now. I found that on the first run the oil/ATF would break down any grease in there and the flex would come out clean and somewhat dry, while I could do 2-3 runs with grease alone and still have a good layer in there when I was done.

I just installed two of the .187 size ones on my fantasm and I like them pretty well other than when you go to put oil in the nipple some of it always pushes it's way through the actual bearing itself and comes out inside of the boat. I only have run these on the bench so far but my drive line seems nice and smooth and the resistance was very minimal. I will report more on these after I actually run them in the lake this weekend. I also didnt mention that you need to debur the insides of these before installation as there was some loose aluminum in both of mine that was left from machining.
Okay, I've had enough runs with the stuffing tube seals now to say that im anfan of them and will install them on most if not all of my future builds. Ive spun them at over 35k rpms and had no problems or water intrusion from the stuffing tube. I just wish someone would get the .187ones in stock again so that I can order more
I'm gonna try it out now.....thx

Yeah, there's some trouble getting that bearing back in stock. They're all on back order.
Bill
order bearing that have seal on one side , no more oil in the boat and easier to get.
anyone try ordering one from aeromarine I beleave there web site shows they have them in stock

The bearings in mine exploded. Aero said they'll send out a new one but haven't received it yet. They seem to be good for oiling your driveline though even if your not using it with the flex saver and other parts etc, I think.
It actually ended up locking up my driveline... so if I didn't notice the busted bearing in time it would have easily caused an entire meltdown in that side.
I think it's good for some setups where water runout is a huge issue and/or lower rpm stuff, otherwise... im sure its just an extra thing to break and cause havoc.
I'm not the only one with these bearing issues-- I have talked to at least 1 other person that had the same thing happen and it was in the similar kind of a high RPM catamaran setup as mine.
The fact that these replacement bearings are no where else to be found is something to consider.
