About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125SH
Delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa, the SC200X125SH is a high-thrust double-acting pneumatic cylinder built for heavy industrial actuation. Its 40 mm diameter piston rod and 33 mm adjustable air cushion provide robust, controlled end-of-stroke deceleration for demanding 125 mm stroke applications.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise position feedback without external brackets. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments where standard seals would degrade.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125SH Is Used
Hot Press & Molding
Viton seals withstand 0-150°C ambient temperatures, making this cylinder ideal for actuating platens and molds in hot press, thermoforming, and rubber vulcanization machinery.
Heavy Material Handling
With over 1.5 tonnes of push force at 0.5 MPa, it powers lift tables, heavy-duty clamps, and large part transfer stations in steel mills and foundries.
Sensor-Controlled Automation
The integrated magnet allows CMSG/DMSG sensors to clamp directly onto the tie-rod barrel, providing reliable end-of-stroke or mid-stroke position signals for automated sequencing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125SH the Right Cylinder?
For applications needing even greater force, consider the SC250 series, which provides 24544 N at 0.5 MPa. If a lower force is sufficient, the SC160 bore offers 10053 N at the same pressure. This 200 mm bore cylinder uses a PT 3/4 port and a M36x2 rod thread. To ensure a correct replacement, match these five points: 200 mm bore, 125 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material (-H).
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 SC200X125SH FAQ
At the standard 0.5 MPa operating pressure, 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 force at 1.0 MPa is 3204 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC200 tie-rod cylinder matching the 125 mm stroke, PT port, magnet option, and Viton seals.
