Bellows Couplings

GAM offers you a complete line of bellows 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.

  • Torque values from 0.44 Nm to 2,500 Nm
  • High torsional rigidity, low inertia, zero backlash and misalignment compensation
  • Can be used at temperatures up to 570°F without any limitations and maintenance free
  • Patented Press-Fit method of joining the bellow to the hubs can withstand harsh environments where glued connections cannot
  • High speeds: rotational speeds up to 25,000 RPM without additional balancing

FAQ

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.
