Their rubber construction allows them to flex and deform slightly to accommodate angular, parallel or axial misalignment between connected shafts.
No, they reduce vibrations without compromising with transmission efficiency.
The choice depends on factors like torque requirements, misalignment tolerance and operating conditions.
Coupling inserts offer flexibility, misalignment compensation, vibration reduction and shock absorption, which rigid couplings cannot provide.
