Description
When your power take-off starts acting up or you’re hearing odd noises from your drive system, the coupling spider might be the culprit. This small but critical rubber component sits between the coupling halves and does the heavy lifting—transferring power while soaking up vibration and dealing with slight misalignment that happens when equipment gets bounced around in the field.
What You’re Getting
- Oil-resistant Buna-N construction that won’t break down from hydraulic fluid or gear oil exposure
- Handles temperature swings from winter storage to summer heat—rated for -40° to +212°F
- Accommodates up to 1 degree of angular misalignment and 0.015 inches of parallel offset
- Direct replacement for worn spiders in L070 coupling assemblies
Built for Real Farm Work
This spider fits L070 series jaw couplings commonly found on agricultural equipment power transmission systems. Whether it’s connecting your tractor’s PTO to an implement, linking pump drives, or handling other moderate-duty power transfer applications, this is the same resilient material that keeps things running smoothly despite the bumps and jolts of field work.
Made to Last
The Buna-N rubber compound is specifically chosen for its resilience and chemical resistance. It bounces back from compression cycle after cycle while resisting the oils and fluids it’ll encounter in farm equipment. The spider’s designed to flex and absorb shock loads that would otherwise damage harder coupling components.
Good to Know
Installation is straightforward—just pull apart the coupling halves and swap out the old spider for the new one. If the spider’s torn or chunks are missing, it’s definitely time for replacement. A quick tip: when you’ve got the coupling apart, check that the coupling teeth aren’t excessively worn—they should engage the spider evenly all around.
