Lovejoy Coupler, L100 X 1-1/4"

The L1001.250 Lovejoy jaw coupling hub (L100 × 1-1/4") is a rugged, vibration-dampening coupling component built to connect shafts while reducing shock loads and protecting equipment. Featuring a 3-jaw design and a SOX (NBR) rubber spider, it delivers reliable torque transfer with no metal-to-metal contact, strong resistance to oil and grime, and fail-safe operation if the elastomer ever gives up. In other words: it keeps power moving and drama down.
