About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80
The SC250X80 is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With an 80 mm stroke, this model is ideal for compact high-force clamping, pressing, and lifting stations where a short, powerful linear motion is required.
This cylinder features a 50 mm diameter piston rod with an M42x2 thread and a 40 mm adjustable air cushion to decelerate the massive payloads typical of this bore class. The body length A is 294 mm, resulting in a total extended length of approximately 374 mm. As an ISO 6430 class cylinder, it is built for robust industrial service with PT1" ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80 Is Used
Heavy-Duty Press Frames
Generates up to 44178 N of force at 0.9 MPa for short-stroke pressing, staking, and assembly operations in automotive and metalworking cells.
Industrial Gate Valves
Provides the high thrust needed to actuate large-diameter gate or knife valves in bulk material handling and water treatment plants with a compact 80 mm stroke.
Structural Testing Rigs
Delivers controlled, repeatable linear force for material testing and structural load simulation, leveraging the robust 50 mm rod and tie-rod construction.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X80 the Right Cylinder?
Select the SC250 bore when your application requires push forces exceeding 18095 N at 0.9 MPa, which is the limit of the smaller SC160 bore (18095 N at 0.9 MPa). For applications needing less force, stepping down to the SC200 bore provides 28274 N at 0.9 MPa. Even with an 80 mm stroke, the large 50 mm rod resists buckling, but any side load must be managed with an external guide or rod support to prevent bearing damage.
For a direct replacement, match five key points: verify the 250 mm bore and 80 mm stroke, confirm the PT1" port thread, ensure the basic (no bracket) mounting configuration, and check that your existing cylinder does not use a magnetic piston (-S suffix). This tie-rod design is dimensionally shorter than a comparable ISO 15552 cylinder and is not interchangeable with that standard.
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 SC250X80 FAQ
At the standard 0.5 MPa operating pressure, the push force is 24544 N and the pull force is 23562 N. At 0.7 MPa, the push force increases to 34361 N. The maximum operating push force at 0.9 MPa is 44178 N.
No, the AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC250 tie-rod cylinder with matching bore, stroke, PT1" ports, and basic mounting.
