Bellows Couplings in Servo Systems: What Engineers Need to Know

R+W America

Bellows couplings are commonly used in applications requiring precise rotation, high speeds, and dynamic motion transmission. With zero backlash and a high level of torsional stiffness, they offer clear performance advantages in many servo-driven systems.

However, successful implementation depends on more than selecting a coupling style alone. Proper sizing, shaft alignment, and installation handling play a critical role in long-term reliability and performance.

This whitepaper provides an overview of bellows coupling construction, typical application benefits, and key considerations for selection and installation.
