Vetus UNIFLEX Flexible Coupling
The Vetus UNIFLEX Flexible Coupling is designed to address the challenge of precise shaft alignment in marine propulsion systems. Its key feature is the ability to accommodate up to a 2° misalignment in the shaft line, ensuring flexibility and preventing stress on the system. This coupling effectively dampens axial and radial vibrations, providing a smoother and quieter operation. It creates a flexible connection between the shaft and gearbox, making it ideal for situations where perfect alignment may be difficult to achieve. However, this coupling is not suitable for use with V-Drives. The maximum allowable shaft RPM for these couplings is 1500 RPM when the shaft line is broken by 2°.
Key Features:
- Allows Shaft Line Misalignment up to 2°
- Dampens Axial and Radial Vibration
- Provides Flexible Connection between Shaft and Gearbox
- Maximum Shaft RPM: 1500 RPM at 2° Misalignment
- Not Compatible with V-Drives
- Available in Various Sizes and Types
