Lovejoy Coupler, L095 X 1"

The Lovejoy L0951.00 Coupler (L095 X 1") is a rugged, fail-safe jaw-style coupling hub designed to transmit torque smoothly while damping vibration—all while staying oil- and grime-friendly thanks to its SOX (NBR/Buna-N) elastomer. With no metal-to-metal contact and a high max speed rating, it’s a solid choice for keeping power transmission reliable (and for keeping your machine from doing the “unplanned interpretive dance” when loads change).

Ideal For

• Power transmission setups needing shock/vibration damping (motors, pumps, compressors, conveyors)
• Applications where oil resistance matters and couplings live a hard life around grime, grease, and moisture
• Systems requiring no metal-to-metal contact for smoother operation and reduced wear
• Operations that value fail-safe performance—it will still function even if the elastomer spider fails
• Builds needing broad fitment flexibility (Lovejoy’s “lots of bore combinations” approach)
