Description
When you’ve got a coupling connection that’s been rattling or showing wear, it’s often the rubber spider in the middle that’s taken a beating. This Buna-N spider sits between your L100 coupling halves, cushioning the connection and handling all the vibration and minor misalignment that comes with running equipment. It’s one of those simple parts that keeps power flowing smoothly from your engine to whatever you’re driving.
What You’re Getting
- Oil-resistant Buna-N rubber that won’t break down from hydraulic fluid or gear oil exposure
- Temperature range from -40° to +212°F covers everything from winter startup to summer field work
- Handles up to 1° of angular misalignment and 0.015″ of parallel misalignment without binding
- Resilient material absorbs shock and vibration to protect your drivetrain components
Built for Real Farm Work
This spider works with L100 series coupling halves commonly found on tractors, balers, mowers, and other agricultural equipment. You’ll see these couplings connecting engines to hydraulic pumps, PTO drives to implement gearboxes, and anywhere you need a reliable power connection that can handle some misalignment and vibration.
Made to Last
Farm equipment puts coupling spiders through a lot—constant vibration, temperature swings, and exposure to oil and grease. This Buna-N rubber compound stays flexible in cold weather and won’t harden or crack from heat and oil exposure like cheaper materials do.
Installation Notes
You’ll need to remove one coupling half to replace the spider, so plan on disconnecting whatever you’re working on. The spider just slides into the center groove—no special tools needed. It’s a good time to check both coupling halves for wear while you’ve got things apart.
