Are you actually after 3 mm pitch belt? It does get confusing with the GT specifications (in which the number does not relate to the pitch).
I would wager that the last one, at least, is licensed, because they mention the Powergrip trademark.
I don't think you should worry TOO much about authenticity, unless you're designing a highly mission-critical machine for sensitive applications, where you have to be able to prove you used authentic parts for safety/regulatory reasons.

Yes, I need 3mm pitch belt (I already have pulleys, and all is designed for them).
I just want to be sure to get a good belt, and I don't pay 15€/m for the same crap chinese guys sell for 2€/m!
I noticed on my belt there are some parts with idlers print: they remain with an angle… I don't use my printer that much, and it often stays in the same position for days; looks like the belt didn't like it...
BTW, how can I see what the core is made of?
-
I once bought steel reinforced belt from ali, and havent had any issue with it.
-
How long of a length do you need? Are you looking for closed loop belt, or an open length? I realize now that Misumi only sells closed loops, but you may be able to get the length you need and cut it.
How long? And which country are you in?
-
I need 4m, in 1 piece… I already checked, and I never found a closed belt > 1m70. So, even if I use 2 belts, it is not enough.
I'm in France.
-
Hmm, I see that the French misumi website doesn't even list the MR3 belt (Misumi uses the number to indicate belt pitch, unlike gates… confusingly).
Perhaps you should buy several types of cheap belt from China, then you can choose the one that looks the best (You should be able to visually see the fiber core from the side or the cut ends).
Pick the one that looks like it was cut the straightest, has no defects in the surface, has the most tensile members, etc.
-
Yes, GT3, 3GT GT 3MR… What a mess! In fact, I'm using old Stratasys parts, which where using GT (first gen, I guess). The Stratasys belts (Gates) are good, even after years.
I'm waiting for Tanals answer, as they sell PowerGrip(R) GT and GT3.
-
Well, it sounds like if there are belts to be had in France, you will find them. Good luck!
-
Pfff, they don't want to sell to individuals
Then they complain we buy in china… It puzzles me.
