About Ortman Fluid Power
Ortman Hydraulic & Pneumatic Cylinders
For 65 years, Ortman Fluid Power has manufactured hydraulic cylinders, pneumatic cylinders, valve actuators, air-oil intensifying boosters, and oil tanks from its Quincy, Illinois facility. Using state-of-the-art CNC machinery, Ortman produces engineered components for manufacturing equipment, mining, infrastructure, power generation, and heavy industry.
Hydraulic cylinder series include 3TH (heavy-duty tie-rod construction, 5,000 psi rated, steel bores 1.5-20"), 7L (medium-duty steel body, 2,300 psi, bores 1.5-14"), and ASH (light-duty precision aluminum tubing, high-pressure capable). Each series features Ortman's proprietary Uni-Cartridge rod gland for quick replacement without cylinder disassembly.
Applications span manufacturing equipment, mining equipment, draw bridges, dam gates, nuclear power plants, timber equipment, and any application requiring reliable hydraulic power transmission. Pneumatic cylinder lines complement the hydraulic portfolio for lower-pressure/explosive-environment applications.
Ortman's engineering includes integrated quick-change rod glands, precision bore tolerances, and pressure ratings supporting continuous duty cycles without fatigue failures. Air-oil boosters provide pressure intensification for specialized applications, while oil tanks include heating/cooling and filtration.
Find the Ortman cylinder series matching your bore size, pressure requirement, and duty cycle, then connect with authorized distributors for pressure testing, custom rod lengths, and integrated system support.

Frequently asked questions
What's the difference between Ortman's 3TH, 7L, and ASH hydraulic cylinder series?
3TH is heavy-duty tie-rod construction for 5,000 psi continuous duty with large bores (up to 20"); 7L is medium-duty steel for 2,300 psi with bores to 14"; ASH is precision light-duty aluminum tubing for compact high-pressure applications. Choose based on pressure, bore size, and duty cycle.
What advantage does Ortman's Uni-Cartridge rod gland offer?
The quick-change rod gland design allows field replacement of cylinder seals and rod without disassembling the cylinder body — reducing downtime and maintenance costs on installed equipment. It's a proprietary Ortman feature across their cylinder lines.
Can Ortman cylinders be customized for my equipment?
Yes — custom rod lengths, port configurations, mounting flanges, and rod-end types are standard. Provide your pressure requirement, bore size, stroke length, and mounting details, and Ortman engineers a solution for your installation.
What's the difference between hydraulic and pneumatic cylinders?
Hydraulic cylinders handle higher pressures (2,300-5,000 psi) for large forces in continuous duty; pneumatic cylinders operate at lower pressures (50-150 psi) for explosive/flammable environment safety and cleaner operation. Choose based on pressure needs and environment.
How do I know if my existing Ortman cylinder can be sealed/rebuilt, or if I need replacement?
Ortman's rod gland design and professional rebuild services support life extension. Inspect for rod wear, seal leakage, and bore damage. Use ChatMRO to find authorized Ortman service centers offering pressure testing and rebuild evaluation.
