1. Product Description
The marine double universal joint driveshaft is a high-performance transmission device specifically designed for marine propulsion systems. It is suitable for ship propulsion systems, steering gear transmissions, deck machinery, and other applications requiring high-torque, large-angle, and dynamic compensation power transmission. Featuring a double Cardan joint (twin universal joint) structure, combined with high-strength materials and corrosion-resistant design, it ensures stable and reliable power transmission under harsh marine conditions (e.g., vibration, shock, salt spray corrosion, and high humidity). It effectively compensates for shaft misalignment and angular offsets caused by hull deformation.Drive Shaft For Boat

2. Product Features:

Harsh Environment Resistance: IP68 protection rating, resistant to salt spray, oil, and seawater corrosion, suitable for船舱 (engine rooms), decks, and underwater transmission scenarios.

High Torque Capacity: Maximum torque range: 5,000 N·m to 200,000 N·m, meeting the demands of large vessel propulsion systems.

Dynamic Compensation: Twin universal joints synchronously compensate for multi-directional deviations (radial, axial, and angular), adapting to hull deformation and power equipment displacement.

Low Maintenance: Sealed bearings and long-life lubrication design reduce maintenance frequency during maritime operations.

Safety Redundancy: Critical components undergo redundant strength verification, complying with classification society standards (e.g., CCS, DNV, ABS).
