About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X180S
The AirTAC SC250X180S is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). Its 50 mm diameter piston rod and 40 mm adjustable air cushion are built to handle substantial industrial loads with controlled end-of-stroke deceleration.
This 180 mm stroke model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The SC series is shorter than an ISO 15552 cylinder, making it a direct replacement only for an existing AirTAC SC250 tie-rod unit with matching bore, stroke, PT ports, and magnet configuration.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X180S Is Used
Heavy Press Tool Actuation
The 24544 N push force at 0.5 MPa drives large forming dies and clamping fixtures in stamping and injection molding presses, with the -S magnet confirming full extension or retraction.
Palletizer & Conveyor Lift Gates
Controls heavy-duty lift gates and pallet stops in high-throughput logistics centers. The adjustable cushion protects the 250 mm bore end caps during rapid cycling of heavy loads.
Structural Test Rigs
Applies controlled, repeatable force up to 44178 N for material fatigue and load testing. The built-in magnet enables precise mid-stroke position verification via DMSG sensors.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X180S the Right Cylinder?
For applications requiring more force, the SC250 is the largest bore in the standard SC range, offering up to 44178 N at 0.9 MPa. If a smaller footprint is acceptable and your force requirement is near 1559 N at 0.5 MPa, stepping down to an SC63 reduces weight and air consumption significantly. Always match replacement cylinders on five points: 250 mm bore, 180 mm stroke, PT port thread, the -S magnet for sensor mounting, and the basic (no bracket) mounting style.
At this bore size, the 50 mm rod is robust, but for any stroke over 300 mm, external guide rails or a guided cylinder assembly are strongly recommended to protect the rod bearing from bending moments caused by side loads.
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 SC250X180S FAQ
At the standard 0.7 MPa operating pressure, the SC250 bore generates 34361 N of push force on the piston and 23562 N of pull force on the rod side. The maximum push force at 0.9 MPa is 44178 N.
No. The AirTAC SC series is a tie-rod cylinder and is shorter than an equivalent ISO 15552 profile cylinder. You must use the dedicated AirTAC F-SC250 series mounting accessories (e.g., F-SC250LB for foot mount, F-SC250TC for trunnion) to ensure correct fit and alignment.
