The PM7 fits shaft diameters between 2 7/16″ – 3 5/8″. It is available as a full assembly, hub only, and shaft only combinations.

PasMac greatly streamlines maintenance and cuts down on spare parts inventory through shaft-diameter standardization. PasMac can mate a driver to any size shaft. Over time, or if installed as part of a plant’s original design, this standardizes gear reducers and driven objects throughout a plant.

5SB stainless bushing or R2 bushing required for installation (sold separately).

Product Description

PasMac is installed between the gearbox and driven object. It is coupled with the driven object’s shaft using a split taper-lock bushing. The PasMac solution reduces equipment damage and provides for easy removal, even in the worst environments.

Series II PasMacs feature an “all-in-one” design, eliminating the need for separate hub and flange pieces.
