Aluminum Alloy Coupling for RC Boat – 4x6mm Shaft Connector

The 4x6mm Aluminum Alloy Coupling is a high-precision motor shaft connector designed specifically for RC boats and DIY marine projects. Made from durable yet lightweight aluminum alloy, this coupling connects a 4mm motor shaft to a 6mm propeller shaft securely and efficiently, ensuring smooth power transmission with minimal vibration.

Its corrosion-resistant build makes it ideal for both freshwater and saltwater environments.

Key Features:

• Material: High-quality aluminum alloy

• Shaft Compatibility: 4mm (motor side) to 6mm (propeller shaft side)

• Durability: Resistant to corrosion and wear

• Construction: Precision-machined for stable and reliable performance

• Fixing Method: Includes grub screws for firm locking

• Color: Typically anodized (silver or black)

Applications:

• RC boats and marine vehicles

• Robotics and mechanical drive systems

• DIY propulsion systems and motor assemblies

Whether you’re upgrading or building from scratch, the 4x6mm Aluminum Alloy Coupling is an essential part for smooth and stable propulsion in your RC boat setup.
