At Multi-Wing flexibility is a key word. Not only when matching the right fan with the duty point, but also when it comes to mounting your fan. Regardless if it is a straight bore for electrical motors, a conical bore for hydraulic pumps, a flange drive on the diesel engine or the bushing for Nema type motors you will find the right hub in the Multi-Wing range. Multi-Wing also helps you find the right fan mounting technique.

Multi-Wing’s mounting technique straight bore is usually used for any application with an electrical motor (EURO norm Motor). This mounting technique implies cylindrical bore in connection with a keyway. The fan is secured with bolt and washer in the end of the motor shaft. In case of smaller bores, the fan is secured with a setscrew.
Multi-Wing’s mounting technique conical bore is usually used for hydraulic motors. This mounting technique implies cylindrical bore mostly in connection with a keyway. The fan is secured with bolt and washer in the end of the motor shaft.
|Bore (i.e. ø16)||Cone (i.e. 1:5)|
|Cone Length (i.e. 22mm)||l (i.e. 62mm)|
|Counterbore (i.e. ø36)|
Multi-Wing’s flange drive is typically mounted on diesel engines, mostly pulley driven and occasionally crankshaft. This technique implies mounting on one pilot hole and a number of bolt holes on a defined bolt-circle.
