R & D Flexible Shaft Coupling for 4" B/W

The R & D Flexible Shaft Coupling is a cutting-edge solution designed for 4" B/W applications, offering a robust and versatile connection between the transmission output flange and shaft coupling. Crafted from a contoured flexible disc molded in a resilient new type polyurethane, this coupling ensures a durable and flexible connection that can handle the demands of marine environments. Its unique design allows for the absorption of vibrations and temporary misalignments, protecting your boat's drivetrain from potential damage. With an 8HP/100RPM capacity, this coupling is ideal for a wide range of marine applications.
  • Engineered for Durability: The polyurethane disc is backed by two metal compression straps, providing a fail-safe design that maintains drive functionality in both forward and reverse, even in the event of a disc failure.
  • Shock Load Absorption: The flexible disc is designed to distort under light shock loads, acting as a sacrificial component to protect your drivetrain from more severe damage.

Key Features and Specifications

This R & D Flexible Shaft Coupling is not just a component; it's a comprehensive solution for protecting your boat's drivetrain. It reduces drivetrain noise and vibration, isolates the shaft, and absorbs shock loads resulting from gear changes or propeller strikes. The polyurethane disc, combined with the metal compression straps, ensures that the system remains in constant compression, extending its lifespan and providing peace of mind.
  • Reduced Vibration: The polyurethane flange creates a flexible barrier that significantly reduces drivetrain noise and vibration, leading to a quieter and smoother operation.
  • Cost-Effective Solution: By absorbing transmission shock loads, this coupling helps to reduce and avoid costly transmission damage, making it a smart investment for any marine enthusiast.

Why Choose R & D Marine Flexible Shaft Couplings?

Choosing the R & D Marine Flexible Shaft Coupling means choosing a product that is designed to enhance the performance and longevity of your boat's drivetrain. Its fail-safe design, combined with its ability to absorb shock loads and compensate for misalignments, makes it an essential component for any marine application. With a focus on durability, noise reduction, and cost-effectiveness, this coupling is a clear choice for those who value the health and performance of their marine equipment.
  • Fail-Safe Design: The coupling's ability to handle both forward and reverse thrust in compression ensures a durable design that can withstand extreme conditions.
  • Enhanced Performance: By reducing vibration and absorbing shock loads, this coupling contributes to a smoother and more reliable operation of your boat's drivetrain.
