| A couple of ranges of couplings to suit most types of motor to shaft combinations Here is a brief list of some of the more common sizes of electric motors we keep|
380 = 2.2mm plain 385 = 2.2mm plain (though 3.17mm sometimes)
400 = 3.17mm Plain 500 = 3.17mm Plain 545 = 3.17Plain 550 = 3.17mm Plain
600 = 3.17mm Plain 700 = 5mm plain 820 = 5mm Plain
900 = 6mm Plain MFA 800/850 = 1/4 Plain MFA Geared 919 type = 6mm Plain
Now Prop Shafts tend to come in two sizes 4ba (4mm) standard for most electric motors and 2ba (5mm) for heavier duty engines now these come with either Plain or threaded ends and depending on the manufacture.
