About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X275
The AirTAC SC200X275 is a large-bore, double-acting tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). With a 275 mm stroke and a 40 mm diameter piston rod, it is built for heavy linear actuation tasks where high force and moderate travel are required.
This model features a 244 mm body length (A dimension), resulting in a total extended length of approximately 519 mm. The adjustable pneumatic cushion (33 mm length) decelerates the piston at stroke ends, protecting the end caps from impact. Standard PT3/4 ports and TPU seals with a -20 to +70 °C operating range are fitted.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X275 Is Used
Heavy Material Handling
Powers lift tables and heavy-duty pushers in logistics centers, moving pallets or large components with 15708 N of force at standard line pressure.
Large Press Tool Actuation
Provides the high clamping and pressing force needed for forming, stamping, or die-casting auxiliary operations in heavy manufacturing cells.
Agricultural Equipment Control
Operates large gates, chutes, or diverters on harvesters and processing equipment, delivering reliable force in dusty, demanding environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X275 the Right Cylinder?
For applications needing slightly less force, the SC160 bore provides 10053 N push at 0.5 MPa, while the SC250 steps up to 24544 N. When using a 275 mm stroke on a 40 mm rod, ensure the load is guided and purely axial; side loads can cause rod bending or bearing wear. An external guide or a guided cylinder is recommended for unsupported loads.
To replace an existing cylinder, match five points: 200 mm bore, 275 mm stroke, PT3/4 port thread, basic (no mounting accessory), and no magnet. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X275 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, push force reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No, the SC200X275 is a double-acting cylinder and will not hold its position if pressure is lost or the valve is centered. The piston can drift or drop. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
