Lovejoy Coupler, L110 X 1"

Lovejoy Coupler, L110 X 1"

The L1101.00 Lovejoy Coupler (L110 X 1") is the industry-standard L Type jaw shaft coupling hub designed to transmit torque while accommodating angular and parallel misalignment. Its fail-safe jaw design continues to operate even if the elastomeric spider fails, while maintaining no metal-to-metal contact during normal operation. Built for demanding environments, it’s resistant to oil, dirt, sand, moisture, and grease, and uses an SOX (NBR) nitrile rubber spider for flexible, oil-resistant performance across a wide temperature range.
