This is a Brand New Motor and Complete GearBox assembly. It has an easy removable 5/8" or 0.625" diameter 16" long shaft (I'm showing the shaft removed, just a simple Allen screw to do that)(any length shaft can be used to fit your application). We wired it for 230 volt 3 phase power and counted the rpm at 280. The 4 bolt mounting flange has a diagonal bolt-hole measurement of 4-3/8"(picture showing). I opened up another unit I have for sale(I opened up) to show the Red colored factory grease and the energy absorbing drive-rod Colet. Call with any interest (952)854-5 seven eight six
P.S. I got this from an over-stock sale. I think this is for an Industrial Paint Machine , or an agitator mixer
