Lovejoy Coupler, L075 X 3/4"

The L075.750 Lovejoy Coupler is a jaw-type flexible coupling hub designed for dependable torque transmission while reducing vibration and misalignment. Sized for a 3/4" bore with 3/16" x 3/32" keyway, this L075 hub is manufactured from sintered iron and uses a SOX (NBR/Buna-N) rubber elastomer spider for smooth, oil-resistant performance. Built to handle demanding speeds up to 11,000 RPM, it delivers reliable power transfer without metal-to-metal contact—because smooth drive systems last longer.
