Description
When you’re connecting shafts on pumps, generators, or other equipment around the farm, you need a coupling that’ll handle the power transfer without constant maintenance. This Lovejoy jaw coupling half is built for connecting 5/8-inch shafts and does the job without needing any grease or oil to keep it running smooth.
What You’re Getting
- Cast iron construction that handles the torque and vibration of farm equipment
- No lubrication needed—install it and forget about it for years
- Hollow head setscrews that grip the shaft securely without slipping
- Flexible design that absorbs shock and compensates for minor misalignment
Built for Real Farm Work
This coupling half works with any equipment that has a 5/8-inch shaft—think irrigation pumps, PTO-driven generators, grain conveyors, and similar machinery. The L50 series is sized right for medium-duty applications where you need reliable power transfer without the bulk of heavier couplings.
Made to Last
The sintered iron construction stands up to the dirt, moisture, and temperature swings that come with outdoor equipment. Unlike rubber or plastic alternatives, this coupling won’t deteriorate from exposure to hydraulic fluid, diesel fuel, or other chemicals you’ll find around the farmyard.
Installation Notes
You’ll need two coupling halves and one rubber spider to make a complete assembly—this is just one half. The hollow setscrews distribute clamping force evenly around the shaft, so you get a solid grip without scoring the metal. A little blue threadlocker on the screws keeps them from backing out over time.
