FAQs

• What is the primary function of a flexible coupling? It compensates for misalignment, dampens vibrations, and facilitates torque transmission between two shafts.
• How do I know if I need a flexible coupling? If your application experiences vibration, misalignment, or shock loading, a flexible coupling is essential.
• Can I use a rigid coupling instead of a flexible one? Yes, but it's pivotal to ensure proper alignment since rigid couplings do not compensate for misalignments.
