Product Description
CCS Certified Hydraulic Transmission Devices
Product Introduction:
The Marine CCS Certified Hydraulic Transmission Devices represent the pinnacle of reliability and performance for modern shipboard hydraulic systems. Manufactured under strict quality control, these devices are fully certified by the China Classification Society (CCS) and have successfully passed the ISO9001 Quality Management System certification. This ensures they meet the rigorous safety, environmental, and operational standards required for global marine applications. To cater to diverse marine engineering requirements, this series features five highly adaptable models: XHSC6, XHSC7, XHSC9, XHSC2.53, and XHSC34.
Key Technical Features:
1.High-Pressure Capability: Engineered to operate efficiently under high pressure, with a maximum allowable casing pressure of 0.8 MPa (special customizations are available upon consultation).
2.Bidirectional Operation: The units support bidirectional rotation, making them highly versatile. Specific rotation directions are detailed in the technical diagrams. If reverse rotation is required, it must be specified at the time of ordering.
3.Robust Brake Options: Available in two configurations to suit various operational needs: Without Brake and With Brake (internal installation).
4.Flexible Output Shaft Configurations: To ensure seamless integration with existing marine machinery, four output shaft types are offered:
Type B: Cylindrical B (Flat Key Shaft).
Type C: Screwed Flange C (Flange connection with screw thread).
Type F: Male Spline Shaft (Rectangle).
Type I: Female Spline Shaft.

Operating & Maintenance Specifications:
To guarantee optimal performance and longevity in harsh marine environments, adhere to the following specifications:
*Hydraulic Fluid: High-quality, anti-foaming, antioxidant mineral hydraulic oil.
*Temperature Range: Ideal working oil temperature is 30°C to 50°C. The allowable range is -20°C to 80°C. When operating below 10°C, low pour-point hydraulic oil must be used.
*Viscosity: Recommended viscosity is 40–60 cSt, with an allowable range of 5–300 cSt.
*Filtration Precision: A recommended filtration precision of 25 μm or higher is required to prevent premature wear.
Installation & Application Guidelines:
1.Mounting: The transmission devices allow for installation in any direction. To guarantee proper lubrication of internal moving parts, the casing must be completely filled with hydraulic oil before operation. The drain pipe positioning must ensure the casing remains full during operation.
2.Distributor Installation: The inlet and outlet oil directions of the distributor can be rotated at intervals of 72 degrees to match the external mounting connection. Caution: When loosening the screws to rotate the distributor, take extreme care not to damage the sealing function of the flat O-ring.
3.Application: These CCS-certified devices are ideal for heavy-duty ship applications, including steering gears, deck machinery, winches, and other hydraulic drive systems requiring compact, high-torque, and reliable power transmission.
