- For a broad overview on Lovejoy jaw couplings, please consider reading: Jaw Coupling Overview – Features & Benefits, Design Basics, and Element Options.
- While Lovejoy jaw couplings are designed to handle a lot of abuse, the jaw coupling elastomeric spider is a wearing element that will eventually need to be replaced. To review how and why jaw couplings wear out, please read: Coupling Failure Analysis – Jaw Couplings (includes hub & spider photos).
- Estimating the life of a jaw coupling is difficult as it is application specific. To dive deeper into this question, check out: Jaw Coupling Question – “How Much Life Can I Expect Out of the Spider”.
