R & D Flexible Shaft Coupling f/5" B/W, Hurth - 20HP/100RPM Capacity

The R & D Flexible Shaft Coupling f/5" B/W, Hurth is an essential drivetrain component for boaters utilizing Hurth transmissions with a 5-inch bore-and-web design. This coupling is engineered to accommodate the demands of 20HP engines operating at 100 RPM, effectively connecting your engine's output shaft to the transmission input while mitigating vibration and misalignment.

Constructed with precision elastomer elements between hardened steel hubs, this flexible coupling dampens torsional vibrations and allows for minor angular and radial deflections, which are critical for a naturally flexible marine drivetrain. Its robust design ensures reliability and performance without the exaggeration often found in marketing claims.

Ideal for operators restoring or upgrading Hurth-equipped vessels, this coupling is also suitable for those replacing worn OEM units that exhibit play or vibration. Its modular design facilitates future service or replacement without the need to remove the entire transmission, making it a practical choice for various marine applications.
