Big Bore Cylinders
PWM Big Bore cylinders are engineered to deliver exceptional force and withstand the most demanding operating environments. Designed for heavy-duty applications, these cylinders feature bore sizes ranging from 10 to 18 inches, providing the power required to move the heaviest loads with precision and reliability. Force output is determined by bore size and operating pressure, and our engineering team ensures each design is optimized to match your load requirements and hydraulic system capabilities.
Every cylinder is tailored to the application, with careful selection of internal components and external construction to meet both performance demands and environmental conditions. Built for rugged use, many designs incorporate bolted construction for enhanced strength and serviceability.
PWM leverages advanced materials, cutting-edge sealing technologies, and proven manufacturing methods to maximize durability and efficiency. Customizable options include:
- High-strength materials such as 4140, QT100, AR, and other alloy/carbon steels
- Induction-hardened rods with enhanced coatings (thick chrome, chrome-over-nickel, alternative finishes)
- Large-bore sealing systems for heavy wear and extreme pressures
- Expanded seal sets for shock resistance and extended service life
- Protective features such as bellows, port guards, and bolt-in glands
- Hardened pins and high-pressure SAE Code 61/62 porting
- Integrated valves (relief, counterbalance, PO check) for protection, load holding, and controlled movement
