R & D Flexible Shaft Coupling f/4" B/W, Hurth - 8HP/100RPM Capacity

The R & D Flexible Shaft Coupling f/4" B/W, Hurth is an essential component for reliable power transmission in inboard marine engines. This coupling is designed for a 4-inch bore and is suitable for various applications, connecting the engine's output shaft to the transmission or gearbox with flexibility that absorbs vibration and misalignment.

With a capacity of up to 8 horsepower at 100 RPM, this coupling is engineered to provide smooth operation under load. Its flexible design accommodates minor angular and axial deflection, which is common in long-running marine powerplants, ensuring precise shaft alignment without introducing slack or play.

Ideal for anglers and cruisers operating smaller inboard systems, particularly those with Hurth transmissions, this coupling offers durability and low-vibration performance during extended running hours. Installation is straightforward, making it a practical choice for those looking to replace or upgrade their existing coupling.
