The PasMac 5S will fit shafts from 2 7/16″ – 3 5/8″ in diameter. Additionally, it requires an 5SB stainless bushing or R2 bushing (sold separately).

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.

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.
