<p style="text-align: center;"><img src="/ueditor/php/upload/image/20260214/1771034650766051.png" title="1771034650766051.png" alt="1.png"/></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">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.</span></p>
