About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400STC
The AirTAC SC200X400STC is a double-acting pneumatic cylinder delivering a substantial 15708 N push force at 0.5 MPa (28274 N at 0.9 MPa). Its 200 mm bore and 400 mm stroke make it a robust solution for heavy-duty linear actuation. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. The standard TPU seals provide reliable performance in ambient temperatures from -20 to +70 C. With a 40 mm diameter rod and PT1/2 ports, it is engineered for demanding industrial environments.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400STC Is Used
Heavy Material Handling
Provides the high force needed to lift, push, or position heavy pallets and components on conveyor systems, especially where a pivoting TC mount is required.
Large Clamping Fixtures
Delivers up to 28274 N of clamping force at 0.9 MPa for securing large workpieces in machining, welding, or assembly fixtures.
Industrial Press Mechanisms
Suitable for acting as the main ram in a small to medium industrial press, leveraging its 200 mm bore for consistent, powerful linear motion.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400STC the Right Cylinder?
For applications requiring less force, consider stepping down to the SC160 bore, which provides 10053 N of push force at 0.5 MPa. This SC200 model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. For a successful replacement, match five key points: 200 mm bore, 400 mm stroke, PT port thread, centre trunnion (TC) mounting, and the integrated magnet (-S) for sensor compatibility.
At a 400 mm stroke, the 40 mm rod is robust, but significant side loads should still be avoided. For applications with unavoidable lateral forces, use an external linear guide or a guided cylinder to protect the rod bearing and ensure long service life.
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 SC200X400STC FAQ
At the maximum operating pressure of 1.0 MPa, the theoretical output force is 3204 kgf. The push force at the standard 0.7 MPa is 21991 N, and at 0.5 MPa it is 15708 N.
No. The AirTAC SC series is a tie-rod cylinder and has a shorter overall body length than an ISO 15552 cylinder. It is only a direct dimensional replacement for another AirTAC SC tie-rod cylinder with the same bore, stroke, mounting, and port thread.
