GAM Couplings

Whether bellows, elastomer, safety, or distance, GAM has a coupling that will meet your requirements.   All GAM couplings are zero backlash and custom machined per order.

Bellows Couplings

GAM offers you a complete line of bellows couplings.  Characteristics of Bellows Couplings include:

  • 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



Elastomer Couplings

GAM offers you a complete line of elastomer couplings.  Characteristics of Elastomer Couplings include:

  • The use of elastomer spiders with shore hardness ratings from 72-D to 98-A permit dampening of vibration caused by system resonance
  • An affordable alternative if high stiffness is not critical
  • The involute shaped teeth of the elastomer spider and jaws are preloaded and will not loosen over time
  • Ensures zero backlash and allows for easy plug-in assembly



Safety Couplings

GAM offers you a complete line of safety couplings.  Characteristics of Safety Couplings include:

  • High torques and single point 360° re-engagement.
  • Low inertia
  • Compensation for misalignment
  • Zero backlash
  •  High torsional stiffness
  • High temperature operation


Distance Couplings

Distance couplings can span axial lengths of 20ft without the need for additional intermediate bearings.  They are precision machined to the required length and are balanced for high speeds.  Their special designs allow for simple installation which make “one person assembly” possible.  Even at these long distances, they remain zero backlash, torsionally stiff, and compensate for shaft mis-alignments to prevent premature bearing failures.  GAM offers you a complete line of distance couplings.  Characteristics of Distance Couplings include:

  • Lengths to 20ft.
  • Compensation for misalignment
  • Zero backlash
  • High torsional stiffness
