The Single Beam flexible coupling is formed from one piece of aluminum rod. A spiral slot is cut through the length of the aluminum tube forming a spring center section referred to as a helical coil or beam.
The flexure allowed by the beam portion of the coupling is capable of accommodating angular, parallel and axial misalignment while continuing to convey power between the attached shafts.
The single beam coupling is designed for very light power transmission applications where accurate positioning of shafts is an essential requirement.
It also has a high tolerance to heat, chemicals and corrosion that would be harmful to conventional elastomeric couplings.
