The Propeller Shaft Coupling from TECHNO CNC is an essential component for marine propulsion systems, designed to efficiently connect the propeller shaft to the engine or motor. Manufactured from high-strength materials like marine-grade stainless steel or alloy steel, this coupling ensures a secure, reliable, and durable connection for smooth power transmission in various marine vessels.
This precision-engineered coupling is built to withstand high-stress conditions in marine environments, offering corrosion resistance, high torsional strength, and longevity under continuous use. Ideal for use in commercial ships, yachts, and other watercraft, the Propeller Shaft Coupling ensures efficient and reliable operation of propulsion systems, contributing to the overall performance and safety of the vessel.
No machining required
No costly machining for tapering and keyway-cutting is required. Just cut the propeller shaft to the correct length and fit the coupling cone.
Secure it to the coupling flange with the bolts provided and the coupling is complete. The shaft coupling provides a high torsional hold without causing shaft damage.
Perfect central alignment
The two-piece conic design gives the coupling perfect central alignment properties and also provides an absolute distortion free coupling fit. Altogether this makes it easier to achieve a correctly aligned driveline, essential for minimal vibration and low noise.
Features and benefits:
• Simplified installation and alignment
• Less vibration and noise
• No machining required
• Two-piece conic design
• Perfect central alignment
• High torsional hold without shaft damage
• Compact dimensions, low weight
• Virtually maintenance free
• Easy to disconnect propeller shaft, without re-adjustment
• Integrated counterhold
• Better onboard comfort
