About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X180
The AirTAC SC200X180 is a double-acting single-rod pneumatic cylinder engineered for applications demanding substantial force within a compact stroke. With a 200 mm bore, it generates a theoretical push force of 15708 N at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and a 33 mm adjustable air cushion at each end to effectively decelerate high inertial loads. The body length A is 244 mm, resulting in a total extended length of approximately 424 mm, making it a robust solution for heavy-duty short-stroke actuation.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X180 Is Used
Heavy Machinery Actuation
Provides the high force needed for clamping, lifting, or shifting mechanisms on agricultural and construction equipment, operating reliably in dusty conditions.
Dock Leveler Control
Powers hydraulic-style dock levelers or heavy bay door mechanisms pneumatically, offering a clean and powerful alternative with 28274 N of peak force.
Industrial Press Feed
Drives material feed systems in large stamping presses or injection molding machines, where consistent, powerful linear motion is critical for cycle timing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X180 the Right Cylinder?
Select the SC200X180 when your application requires a 200 mm bore cylinder with a 180 mm stroke. For higher force at the same bore, consider stepping up to the SC250 series, which provides 24544 N of push force at 0.5 MPa. If a lower force is acceptable, the SC160 delivers 10053 N at the same pressure.
When replacing an existing cylinder, ensure compatibility across five key points: bore (200 mm), stroke (180 mm), port thread (PT 1/2), mounting style (basic, no accessories), and the presence of a magnet (this model has no built-in magnet). For strokes over 300 mm, consider external guides to protect the rod from side loading, though at 180 mm this is typically not a concern.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X180 FAQ
At 0.7 MPa (7 bar) operating pressure, the SC200X180 double-acting cylinder produces a theoretical push force of 21991 Newtons. The pull force on the return stroke is 15080 N due to the 40 mm rod reducing the effective piston area.
No, the AirTAC SC series is a tie-rod design and is physically shorter than a standard ISO 15552 cylinder. It is not dimensionally interchangeable. It must only replace another AirTAC SC tie-rod cylinder with the same 200 mm bore, 180 mm stroke, and PT port configuration.
