Lovejoy Coupler, L075 X 5/8"

The L075.625 Lovejoy Coupler is a jaw-type flexible coupling hub designed to deliver smooth, reliable torque transmission while absorbing vibration and minor misalignment. Sized for a 5/8" bore with a 3/16" x 3/32" keyway, this L075 hub is constructed from sintered iron and pairs with a SOX (NBR/Buna-N) rubber spider for oil-resistant, flexible performance. Rated for speeds up to 11,000 RPM, it’s built to keep drive systems running efficiently without metal-to-metal contact.
