Yes, only if the mixer's impeller is not attached to a long shaft. The impeller is subjected to radial loads, and the HSM bearings provide the shaft support. The HSM's compact bearing span makes it unsuitable for supporting radial loads applied at long distances from the reducer.
There are many accessories for use with the Helical Shaft Mount (HSM). Our patented Taper Grip Bushing is well suited for any application. A motor mount, backstop, torque arm, ABS belt guard, belts, breathers, sheaves and harsh duty seals are all accessories that work well with the HSM for any application. Also available are screw conveyor shafts, screw conveyor adaptor kits and screw conveyor seal kits. Contact your local representative for more information.
