About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X280
The AirTAC SC200X280 is a double-acting tie-rod cylinder that generates 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 280 mm stroke and a 40 mm diameter piston rod, this model is built for heavy linear actuation tasks where robust force output is non-negotiable.
Its body length A measures 244 mm, giving a total extended length of approximately 524 mm. The adjustable pneumatic cushion (33 mm length) decelerates the piston smoothly at stroke end, reducing impact stress. PT1/2 ports and an M36x2 rod thread provide secure, high-flow connections for demanding industrial circuits.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X280 Is Used
Heavy Press & Clamping
The 28274 N thrust at 0.9 MPa makes the SC200X280 ideal for hydraulic-press alternatives, assembly jigs, and heavy-duty clamping fixtures requiring consistent, controllable force.
Palletising & Material Handling
With a 280 mm stroke and 15.7 kN push at 0.5 MPa, this cylinder reliably lifts, pushes, or positions heavy pallets and bulk materials on conveyor transfer stations.
Large Valve & Damper Actuation
The adjustable cushion and robust tie-rod construction suit the SC200X280 for modulating large process valves or dampers, where smooth end-of-stroke deceleration protects the valve seat.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X280 the Right Cylinder?
Choose the SC200X280 when your application needs roughly 15.7 kN of force at standard plant pressure. If the load is lighter, stepping down to the SC160 bore (10053 N push at 0.5 MPa) can reduce air consumption and physical size. For strokes of 280 mm and above, always evaluate side-load conditions—an unsupported 40 mm rod can experience bending stress under offset loads, so consider an external guide rail or a guided cylinder if the load is not perfectly axial.
For a direct replacement, match five points: 200 mm bore, 280 mm stroke, PT1/2 port thread, basic (no mounting accessory), and no magnet. This ensures the mounting footprint, force curve, and cushion performance are identical to the original AirTAC SC unit.
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 SC200X280 FAQ
At 0.7 MPa supply pressure, the SC200X280 produces 21991 N of push force on the piston and 15080 N of pull force on the retract stroke. The theoretical maximum at 1.0 MPa is 3204 kgf.
This specific model code SC200X280 does not include the -S magnet option, so the piston does not carry a magnetic ring. To use CMSG/DMSG/EMSG sensors, order SC200X280-S instead. The standard model still accepts all mechanical mounting accessories like foot, flange, or clevis brackets.
