Our Power Grinder grain mill motor packages come with a 22mm bore Lovejoy shaft coupler for the motor shaft, a shaft coupler for your mill*, and a rubber buna spider which provides a cushion between the two Lovejoy couplers.
If you need to order a separate Lovejoy coupler, please make your selection here.

As an official Lovejoy distributor, we can provide any coupler or component Lovejoy manufactures.
*Select the size of coupler which corresponds with the diameter of your grain mill shaft and add to your cart!
If your mill shaft is keyed, please select a coupler with a keyway.
We can special order all sizes and types of Lovejoy components.
We stock the L075 series of Lovejoy jaw coupler components, which correspond with the shaft sizes of most production grain mills.
We have chosen this series of coupler because it is the smallest diameter of coupler which offers a 22mm bore.
The shaft of the All American Ale Works Power Grinder grain mill motor is 22mm in diameter.
The Jaw Type couplings from Lovejoy are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy duty electrical motor and internal combustion power transmission applications.
Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors. Lovejoy’s Jaw Type couplings are available in 24 sizes from a minimum torque rating of 3.5 in–lbs (0.4 Nm) to a maximum torque rating of 170,004 in–lbs (19209 Nm) and a bore range of .125 inches (4.45mm) to 7 inches (178mm). Lovejoy’s standard bore program covers AGMA, SAE, and DIN bore/keyway and spline bore combinations.
Lovejoy Jaw Type couplings generally consist of two hubs (available in sintered metal, aluminum, bronze, steel, stainless steel, and ductile iron), and an elastomer element, known as a spider or cushion (materials available include NBR SOX rubber, Urethane, Hytrel®, and Bronze).
