Description
When your coupling starts making noise or you notice more vibration than usual, there’s a good chance the spider in the middle needs replacing. This flexible rubber element is what absorbs shock and compensates for small misalignments between shafts—and when it wears out, you’ll know it. This Buna-N spider gets your L110 coupling running smooth and quiet again.
What You’re Getting
- Oil-resistant Buna-N material that stands up to hydraulic fluid, diesel, and grease
- Handles misalignment up to 1 degree angular and 0.015 inches parallel
- Works in temperatures from -40°F to +212°F—perfect for year-round farm use
- Direct replacement spider that installs in the center of L110 coupling bodies
Built for Real Farm Work
L110 series couplings are workhorses you’ll find connecting PTOs, hydraulic pumps, and drive systems on all kinds of farm equipment. Whether it’s a feed mixer, manure spreader, or irrigation pump, this spider handles the constant starts and stops that come with farm work. It’s designed to absorb shock loads and keep things running even when shafts aren’t perfectly aligned.
Made to Last
The Buna-N rubber construction resists oil, fuel, and chemicals while staying flexible in both summer heat and winter cold. This isn’t some cheap knock-off—it’s the same quality material Lovejoy uses in their original equipment. The resilient design bounces back from compression cycles and keeps working season after season.
Good to Know
You’ll need to remove one coupling half to get the old spider out and the new one in. Remember, a complete coupling assembly needs two body ends plus one spider in the middle. If you’re doing the work yourself, mark the coupling halves before you take them apart so they go back together in the same position.
