 Quality, Strength and Economy..... If your
priorities for a coupling are Quality, Strength and Economy then specify Magnaloy's Type
PM Model 90 coupling. The Magnaloy PM90 coupling is made from high-density powdered metal
offering high strength and low cost construction. Double set-screws standard with all bore
sizes 1/2 inch and over. The set-screws are placed over the keyway and at a 45° angle to
the keyway to allow greater hoop-stress and maximum shaft gripping. Increased drive lug
surface area provides low unit loads on the insert drive elements while allowing more
rapid heat dissipation. The PM90 coupling utilizes Magnaloy's exclusive "radial drive
lug design", providing even, compressive loading of the insert. This design
eliminates the heat generating radial loading component and maximizes insert life. The
insert design allows easy installation and replacement without hub removal. Inserts are
available in standard, Nitrile, and optional, Urethane and Hytrel, materials. To receive a descriptive
product brochure on the Magnaloy PM90 Couplings please complete the request form below.
