Flexible coupling shaft can connect your driving shaft with the driven shaft .it is very efficient in eliminating to the possible extent. Minimum backlash is another great advantage of this aluminum flexible coupling.this flexible coupling with the outer diameter is machined aluminum coupling. First bore diameter is 3mm and second bore diameter is of 3mm also.
Its comes with the spiral cut in the middle along the length which makes it flexible so they can make be shafts even they are not perfectly co-linear and will help to reduce binding effects. So couple are also known as beam coupling, helical coupling and flexible coupling
