When your priorities for a coupling are economy and strength, we specify the all-new Magnaloy Type PM90. The PM90 is made from high-density powdered metal and is available in stand ard bores up to 1.125 inch maximum. Double set screws are standard in all bores 0.5 inch and over. The set screws are placed over the keyway and at a 45 degree angle to the keyway to allow greater hoop-stress generation and maximum shaft gripping. The increased drive lug surface area on the PM90 provides low unit loads on the insert drive segments while insuring more rapid heat dissipation. MagnaloyÕs exclusive insert design allows easy installation and replacement without hub removal. The drive lug design provides even compressive loading with no radial loading of insert drive elements. Show more
