Lovejoy Coupler, L075 X 1/2"

Lovejoy Coupler, L075 X 1/2"

The L075.500 Lovejoy Coupler is a jaw-type coupling hub designed for reliable torque transmission and vibration dampening in light- to medium-duty power transmission applications. Built from sintered iron and paired with a SOX (NBR) rubber spider, this L075 hub delivers smooth performance, oil resistance, and fail-safe operation—because keeping shafts aligned and cushioned keeps equipment running longer.
