Lovejoy Coupler, L090 X 7/8"

Lovejoy Coupler, L090 X 7/8"

The L090.875 Lovejoy Coupler Hub is a jaw-style coupling hub designed for dependable torque transmission in industrial and agricultural drive systems. Constructed from sintered iron and built for use with an SOX (NBR) rubber spider, this L090 hub provides vibration dampening and shock absorption while preventing metal-to-metal contact. With a 7/8" bore and keyed configuration, it’s engineered for secure shaft engagement and smooth, reliable performance.
