accouplement universel en métal pour bateau 22mm x 10mm x 4mm arbre
molto belle ottimo materialeplusplusplusplusplusplusplusThis one is machined quite well, maybe a bit loose fit on a 4mm shaft. the problem with this thing is the lubrication, the materials dont like dry running. In my case, some 30k rpm boat setup and just spraying grease on it let it run for only 20 times approx. it can take a lot of torque, for sure, so ill try an oil bath maybe, but on the next boat i wont use it anymore.bought these to replace the ones on my Traxxass outdrives - they are shorter overall, so I will have to rig something up as a spacer, otherwise they look pretty nice, may work in the NDQ. They are nice and small.Megri az rt,de kr hogy nincs ms mretben.
