Fluid Couplings
Dear Mekhan,
the very best i feel that you could do at this stage is to seek / google 'supplier fluid coupling' and to check "fluid coupling" at youtube, there's much information, also improved by images and imaged representations.
as to 1): the coupling as such will live as long as the bearings live, thus 10 ys. + should be a baseline. Design / correct appreciation of anticipated loads is however essential.
as to 2): Or the melting fuse gives way --> reason is overload / too long start - up if used at belt conveyor drive / Or bearings fail --> design / utilization / operational issue (lubrication)
as to 3): This will be as per supplier information, an example would be Alumina cast ALSi10Mg.
All of above can still be further elaborated and complemented.
P.S.:
Your post was made a new thread in order to keep it a dedicated from previous discussion subject, pls. understand / accept.
Thank you
Regards

Dear Mr.Mekhan,
I addition to Mr.Ronald's valuable reply, hope you may consider the following also.
1. If the fluid coupling has oil seals, in your selection, the seals life would be shorter than the bearings life.
2. There are incidences ( in my experience ), though fusible plug got blown, I could not find the reasons. After through checking of conveyor, oil & plug were replaced. Conveyor was started. It was running smooth. What made the plugs to blow away was mystery to me.
In contrary to above point, there were serious damages to conveyors. But fluid couplings failed to protect the conveyor.
3. Please check up with supplier. Fluid couplings are mostly made of Aluminium costings ( as far I know ).
Personally, I like Variable Frequency Drives , more than those of fluid couplings.
There are many threads & discussions in this forum. Please go through.

Dear Makhen,
All the above advices are right.
Most important is the correct selection of fluid couplings,its installation and commissioning.
I have come across few installations,which has suffered a lot due to improper selection.
Reputed Fluid coupling manufacturers can help you in this regard.
Variable frequency drives eliminate the necessity of fluid couplings,but it has plus and minus points,while considering CAPEX/OPEX.
