Hydraulic Cylinders
Since 1977, Powermatics had led the industry as a trusted manufacturer of high-quality hydraulic cylinders for the OEM market, engineered to perform in harsh environments like offshore, construction, heavy industry and waste management.
Product Overview
Hydraulic cylinders can be engineered for a wide range of applications, offering innovative designs tailored to unique operational needs. Known for their durability, power efficiency, and load-handling capability, hydraulic cylinders are often the superior choice in industrial scenarios. They provide precise control, versatility, and reliable performance with low maintenance requirements.
Our technical team work closely with clients to design and manufacture cylinders that meet precise specifications, ensuring exceptional performance and durability.
Types of Hydraulic Cylinders
PHE hydraulic cylinders are available in several types, each designed for different functions:
- Single Acting and Displacement Cylinder: Actuated by pressure on one side; returns to initial position by external forces.
- Spring Return Single Acting Cylinder: Commonly used for locking, clamping, braking, and load holding applications.
- Double Acting Cylinder: Capable of both pushing and pulling applications, most widely used across various industries.
- Telescopic Cylinder (Multiple Stages): Suitable for single or double acting applications. These cylinders offer long strokes with a compact cylinder length, albeit with a more complex and typically higher cost construction.
Advanced Features
Our hydraulic cylinders can be integrated with a range of advanced features to enhance their functionality:
- Valves: Including PO check valves, counterbalance valves, cushioning feature, and more.
- Sensors: Position sensors such as inductive sensor, linear displacement transducer and other monitoring capabilities.
- Other Custom Designs: Such as double rods, tandem design, piggyback setup, booster cylinder, hydraulic rotary, and beyond.
