Hydradrive HD-130 Constant Velocity Propeller Shaft Drive Kit with Thrust Bearing and Adapter

Hydradrive HD-130 Constant Velocity Propeller Shaft Drive Kit with Thrust Bearing and Adapter

The Hydradrive HD-130 Constant Velocity Propeller Shaft Drive Kit is designed for marine propulsion installations requiring high torque transmission and dedicated propeller thrust support. The complete system combines a homokinetic (constant velocity) drive shaft, a thrust bearing and a gearbox adapter.

The HD-130 is specified for marine engines up to approximately 250 HP, with applications on planing boats up to 320 HP. It accommodates propeller shaft diameters of 40, 45, 50, 55 and 60 mm.

The constant velocity shaft transmits torque between the marine gearbox and propeller shaft while accommodating angular displacement. The dedicated thrust bearing transfers propeller thrust directly to the vessel's hull rather than through the engine and gearbox mountings.

Propeller Shaft Compatibility

Constant Velocity Drive and Thrust Bearing

The Hydradrive HD-130 uses a constant velocity drive shaft to transmit torque between the gearbox and propeller shaft while accommodating angular differences between connected components.

The dedicated thrust bearing provides a mounting point for propeller thrust loads, directing them into the hull rather than through the engine and gearbox mounting system.

This arrangement allows the propulsion system to accommodate shaft alignment differences while reducing the transmission of vibration through the drivetrain.

Selection and Installation

Before ordering, verify the following installation requirements:

• Engine power: Up to approximately 250 HP, or up to 320 HP for the specified planing boat application.
• Maximum shaft torque: 1,800 Nm.
• Maximum propeller thrust: 25,000 N.
• Propeller shaft diameter: 40, 45, 50, 55 or 60 mm.
• Gearbox: Manufacturer, model and reduction ratio.
• Output flange: Bolt circle diameter and centering dimensions.
• CV shaft length: 240 ± 45 mm.

The gearbox adapter and propeller shaft connection must be selected according to the specific installation requirements.
