ES Series - Single Beam Set Screw Style Couplings - Metric Bores
Beam Style Couplings (ASB, ES/EC, & ADB Series)
-
The 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.
This results in a single piece, true flexible coupling.
The Miniature Beam coupling is designed for very light power transmission applications where accurate positioning of shafts is an essential requirement. It also has a very high tolerance to heat, chemicals, and corrosion that would be harmful to conventional elastomeric flexible couplings.
The Miniature Beam coupling design is very well suited for small shaft applications and the inherent requirements of start/stop/reverse applications where zero backlash and extreme positioning accuracy are important. This coupling operates either clockwise or counter clockwise without sacrificing windup or torque capabilities.
