About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350
The SC200X350 is a robust double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter piston rod and 33 mm adjustable air cushion are built to manage substantial inertial loads in heavy-duty linear motion tasks.
With a 350 mm stroke and a compact body length A of 244 mm, this genuine AirTAC actuator provides a total extended length of approximately 594 mm. The PT3/4 port ensures high flow for responsive cycling, making it a reliable workhorse for demanding industrial environments.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350 Is Used
Heavy Press Feed
Pushes heavy steel blanks into a stamping press with 15.7 kN of force at standard shop air, maintaining cycle speed under high inertia.
Mold Clamp Actuation
Provides the clamping force for medium-tonnage injection molds, leveraging the 28 kN peak thrust at 0.9 MPa for secure mold closure.
Pallet Lift & Transfer
Drives a heavy-duty pallet lifting mechanism, raising loaded pallets with consistent force from the 40 mm rigid piston rod.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350 the Right Cylinder?
Select the SC200X350 when your application requires force in the 15-28 kN range. For a step down in force, the SC160 bore offers 10053 N at 0.5 MPa; for equivalent force in a tie-rod design, the SC250 bore provides 24544 N. At this 350 mm stroke, ensure the 40 mm rod is protected from side loading—external guides or a guided cylinder are recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match five key points: 200 mm bore, 350 mm stroke, PT3/4 port thread, basic mounting (no brackets), and confirm the absence of a magnet. This SC cylinder is not an ISO 15552 profile and is dimensionally shorter.
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 SC200X350 FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No, the SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It can directly replace another AirTAC SC200 tie-rod cylinder with matching bore, stroke, PT3/4 port, and basic mounting.
