Construction Cylinders
Hydraulic cylinders are used on a wide variety of construction and off-road equipment. Large bore and heavy duty fluid power components are often necessary for machinery that operates in rough and rugged conditions. These machines require high pressure ratings and frequently need bolted construction to maintain cylinder strength under heavy loads.
PWM has more than 40 years of expertise in the design and supply of hydraulic cylinders for Original Equipment Manufacturers in the construction industry. PWM custom designed cylinders consistently meet the quality and dependability expected by manufacturers and equipment users.

PWM understands the extreme demands placed on hydraulic systems in the off-road equipment industry. Our heavy-duty hydraulic cylinders are engineered, customized, and precision-built to perform reliably under the toughest field conditions—ensuring consistent power, durability, and safety across all applications.
Our technical sales and engineering teams work closely with OEMs to analyze and understand every operational variable that may influence hydraulic cylinder design. These include:
- Continuous Duty Cycles – extended equipment operation requiring consistent and repeatable cylinder performance
- Load Capacity – accommodation of high mechanical loads and dynamic stresses
- Operating Environments – performance stability in extreme heat, cold, moisture, or abrasive conditions
- Material Interaction – exposure to soil, salt, debris, and corrosive or abrasive elements
- Operating Pressures – design optimization for high PSI ranges and demanding duty cycles
- Contamination Risks – cylinder placement and protection against dust, dirt, and debris ingress
- Mechanical Impact and Fatigue – analysis of vibration, shock, and cyclical stress exposure
- Precision and Control Requirements – integration of advanced position-sensing technology for accuracy
- Fluid Compatibility – material and seal selection for petroleum, water-based, or fire-resistant fluids
- Environmental Protection – secondary sealing systems, containment strategies, and leak detection
- Maintenance Accessibility – service-friendly designs allowing easy disassembly and part interchangeability
PWM’s engineering expertise spans the latest advancements in metallurgy, seal technology, and cylinder manufacturing. We provide a full range of bore and stroke configurations, along with extensive custom design options such as:
- High-strength materials (e.g., 4140, QT100, AR100, and advanced alloy steels)
- Induction-hardened and chrome-over-nickel plated rods for superior wear and corrosion resistance
- Advanced seal systems engineered for high-pressure, high-wear, and extreme environments
- Shock-resistant seal configurations and external protective bellows
- Bolt-in gland designs for enhanced structural integrity
- High-pressure porting (SAE Code 61/62 flange patterns)
- Integrated valve systems (relief, counterbalance, PO check) for controlled actuation and protection
- Position sensing and feedback technologies for precision motion control
- Replaceable bushings and bearings to simplify field service
- Hardened pins and custom mounting geometries to maximize durability and contact surface
