Elastomer Couplings

GAM Elastomer Couplings GAM offers you a complete line of elastomer couplings. We can help you define your coupling needs and offer you technically superior and cost-effective solutions. Our extensive manufacturing capabilities and highly skilled machinists enable us to customize your couplings for your exact applications and we offer same day delivery for custom bored couplings.


  • Elastomer spiders dampen vibration caused by system resonance
  • Affordable alternative to bellows couplings if high stiffness is not critical
  • Involute shaped teeth on the elastomer spider and jaws are preloaded and will not loosen over time.
  • Ensures zero backlash and allows for easy plug-in assembly
  • Custom bored to your application

Can keyways be machined into GAM couplings?

Keyways are not recommended by GAM as they can actually introduce backlash into machine systems overtime. While not recommended, keys can still be machined into the couplings upon request.
