FAQs

We understand that selecting the right flexible shaft coupling can be a complex process, and you may have questions or concerns. Feel free to explore our comprehensive FAQ section, where we address common queries and provide insights to help you make an informed decision.

1. How do I determine the appropriate flexible shaft coupling for my marine application?

Selecting the appropriate flexible shaft coupling involves considering factors such as engine horsepower, gearbox type and reduction ratio, as well as the specific dimensions of the gearbox flange. Our experts can guide you through this process, ensuring you choose the optimal solution based on your unique requirements.

2. Can flexible shaft couplings accommodate misalignments between the engine and shaft?

Absolutely. One of the key advantages of our flexible shaft couplings is their ability to accommodate temporary misalignments between the engine and shaft, which can occur due to flexing of the boat structure or movement of the engine on its vibration isolation mountings. The contoured flexible disc design allows for free flexing, ensuring seamless power transmission despite minor misalignments

3. How often should flexible shaft couplings be inspected or replaced?

It’s advisable to inspect the coupling during scheduled maintenance intervals or whenever unusual vibrations or noises are detected. Depending on usage and operating conditions, flexible shaft couplings may need to be replaced periodically to ensure optimal performance and reliability, as recommended by the manufacturer.
