R+W Metal Bellows Couplings Provide Precision Accuracy and Dynamic Motion


Bellows couplings are a form of a flexible coupling and they compensate for misalignment. They provide precise transmission of velocity, angular position, and torque. Bellows couplings are known for their high torsional stiffness, which allows for flexibility when dealing with axial, angular and parallel shaft misalignment. The bellows absorb any slight misalignments between the mounting surfaces of two components. They tend to have the highest torsional stiffness of any servo motor coupling and are therefore used in applications that require high positioning positions. Backlash-free, torsionally rigid metal bellows guarantee the precise positioning of the driven load and can be used in highly dynamic cyclic duty applications.
