Single piece structure with anti-vibration rubber molded between the two hubs

Available in high torque variety XGT

Identical clockwise and counter-clockwise rotational characteristics

Excellent electrical insulation

Operational temperature: -20℃~80℃

Split Coupling

Easy attachment and removal

In Pursuit of Optimal Design
Using the latest FEM analysis techniques, the construction of the anti-vibration rubber is designed to yield high torsional stiffness and torque. Additionally, the shape is designed to relieve stress from the jaws' inner diameter. By distributing stress uniformly throughout the jaw, product longevity is significantly increased (patent pending)
