RRS/RRSC Type – Radially Removable Spacer Coupling
- Center “drop out” to provide proper shaft separation
- Easy elastomer installation (no disturbing hubs or realignment)
- Accommodates American and European industry standard pump/motor shaft separations
- Spacer is made of glass reinforced plastic, cast iron, or aluminum

- 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”.
- Lovejoy L line jaw coupling hubs through size L150 are manufactured out of sintered iron. This is a well proven technology that has been used by Lovejoy for decades and can be re-bored locally similar to other standard coupling hub materials. Should you have any further concerns, please see the following article: Can I Rebore Sintered Iron Coupling Hubs?
- And, because it has an interesting back story and is a fairly common question we get asked: What do Lovejoy jaw coupling numerical sizes stand for?
