PRODUCT OVERVIEW
Product Overview
Structural Diagram of C-Series Marine Hydraulic Cylinder
Explanation of Model Coding for C-Series Marine Hydraulic Cylinders
The C-series marine hydraulic cylinder is a hydraulic actuator specifically designed for marine and offshore environments; it primarily comprises two main series: **double-acting piston-type (CDE/CDG)** and **single-acting plunger-type (CZE/CZG)**.
- Model example: CDE100—"C" stands for marine application, "D" for double-acting, "E" for a 16 MPa pressure rating, and "100" for a cylinder bore of 100 mm.
It features a compact design and utilizes seawater-resistant materials and surface treatment processes, making it suitable for the drive and control of various deck machinery, such as ship rudders, hatch covers, cranes, and anchor winches.
