As a key component of CPP, the Propeller Blade Carrier's main function is to support the blades and transmit torque. The Propeller Blade Carrier is connected to the CPP blades by bolts. Under the action of the piston and the slider, the Propeller Blade Carrier can rotate the angle and drive the CPP blade to rotate, thereby changing the pitch.

Product Features
High-strength load-bearing design: Made of high-quality alloy steel and stainless steel, strengthened by heat treatment to ensure high torque transmission capacity.
Precision machining: Precision machining by CNC machine tools to ensure precise matching with the blades, pistons and sliders to reduce friction loss.
Dynamic adjustment capability: Driven by hydraulic pistons or mechanical sliders, the blade angle can be accurately adjusted to achieve optimal propulsion efficiency.
Wear-resistant and corrosion-resistant: The surface is treated with special coatings or plating to improve resistance to seawater corrosion and wear and extend service life.
Modular design: Easy to install, maintain and replace, suitable for different models of CPP systems.

Propeller Blade Carrier is manufactured using high-strength alloy materials and precision machining technology to ensure excellent mechanical strength, corrosion resistance and long-term stability in harsh marine environments. It is suitable for all types of commercial ships, offshore engineering vessels and warships.

  • What is the difference between a fixed-pitch propeller and an Controllable Pitch Propeller?

    A fixed-pitch propeller (FPP) has blades permanently set at a single angle relative to the hub — once manufactured, the pitch cannot change during operation. A controllable pitch propeller (CPP), by contrast, uses a hydraulic or electro-hydraulic mechanism inside the hub to rotate each blade around...

  • How Do Propeller Energy Saving Devices Work?

    Propeller Energy Saving Devices (ESDs) work by optimizing the hydrodynamic environment around a ship's propeller — either before, at, or behind the propeller plane — to reduce rotational energy losses in the slipstream, improve the uniformity of inflow, suppress cavitation, or recover rotational ki...

Industry Knowledge Extension

The Propeller Blade Carrier is the core structural component and power transmission unit in an adjustable propeller (CPP) system. It is installed inside the propeller hub, and its core function is to act as a mounting base for the blade, carry the blade and transmit the huge thrust and torque generated by hydropower to the hub and stern shaft. At the same time, it is connected to the servo piston through the rear connecting mechanism, accurately converting the linear motion of the piston into the rotational motion of the blade, thereby realizing the adjustment of the pitch angle.

The manufacturing of this component faces significant technical challenges. The materials must be made of high-level Ni-Cr-Mo special alloy forged steel to ensure extremely high strength, toughness and corrosion resistance, and be able to withstand decades of alternating loads in the marine environment. In terms of machining, its shape is complex and includes multiple high-precision bearing positions and mating surfaces. The dimensional tolerances and shape tolerances of these key parts must be controlled within extremely strict ranges (usually up to IT6-IT7 level accuracy) to ensure a perfect coordination with the entire system. The manufacturing process also requires strict tempering and heat treatment to optimize material performance, and 100% non-destructive testing (including ultrasonic and magnetic powder flaw detection) must be carried out to ensure that there are no defects inside and on the surface.

Zhenjiang Jinye Propeller Co., Ltd. has shown its core advantages in the manufacturing of this component. The company has the full process capability from collaborative design to precision manufacturing. The advantage is that it can integrate the blades, hubs and Blade Carrier to ensure optimal system performance. Relying on advanced equipment such as large five-axis CNC machine tools, the company can achieve micron-level machining accuracy control. At the same time, from forging materials to finished products, the company implements a complete quality traceability system to ensure that every product that leaves the factory has impeccable reliability. Its products have rich experience in real-ship application, which also proves its excellent stability and long life.
