GAM,  USA made, providing bellows couplings, elastomer couplings, safety couplings, and distance couplings. Produced for demanding and dynamic applications. GAM Elastomer couplings are zero backlash and provide vibration / resonance dampening while still compensating for shaft mis-alignments. A lower cost alternative to bellows style couplings. GAM Bellows Couplings are zero backlash and the most torsionally stiff solution for dynamic applications while still compensating for shaft misalignments. Wear and maintenance free even in high temperatures.
