Lovejoy Coupler, L070 X 3/4"

Lovejoy Coupler, L070 X 3/4"

The L070.750 Lovejoy Jaw Coupling Hub (L070 x 3/4") is a precision-machined coupling hub designed for use in Lovejoy L070 jaw coupling assemblies, providing reliable torque transmission between rotating shafts. Constructed from durable sintered iron, this hub is engineered for long service life while maintaining excellent strength and wear resistance. Designed to work with a Buna-N (NBR) rubber spider, the coupling absorbs vibration and shock while preventing metal-to-metal contact. The 3/4" bore with a 3/16" x 3/32" keyway ensures a secure shaft connection, making it well suited for pumps, motors, gearboxes, and other power transmission equipment. In short, it’s a compact coupling component that quietly keeps machinery spinning smoothly without shaking itself apart.
