About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50SH
The AirTAC SC250X50SH is a large-bore double-acting tie-rod cylinder delivering a substantial 24544 N of push force at 0.5 MPa (44178 N at 0.9 MPa). With a 50 mm stroke and a 50 mm diameter piston rod, this unit is built for short, high-force clamping, pressing, or lifting strokes in demanding industrial environments.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to be mounted directly on the barrel for precise end-of-stroke detection. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0-150°C, making it suitable for high-temperature applications where standard seals would fail. Ports are standard PT1".

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50SH Is Used
Hot Press Lamination
Viton seals handle 0-150°C ambient temperatures, making this cylinder ideal for hydraulic-free hot press platens in plywood or composite lamination where high force and heat resistance are critical.
Heavy Die Cushioning
The 24544 N force at 0.5 MPa provides ample power for short-stroke die cushion or stripper plate actuation in metal stamping, with sensor feedback for cycle confirmation.
Furnace Damper Actuation
With a 0-150°C rating, this cylinder can directly actuate large dampers or flue gates near furnaces and ovens, providing reliable pneumatic control without complex thermal shielding.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50SH the Right Cylinder?
Select the SC250 for applications requiring the highest force output in the SC family. If 24544 N at 0.5 MPa exceeds your requirement, consider stepping down to the SC200 bore, which provides 15708 N of push force at the same pressure. For replacement, ensure a 5-point match: 250 mm bore, 50 mm stroke, PT1" port thread, the built-in magnet (-S) for sensor compatibility, and Viton seals for high-temperature operation. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
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 SC250X50SH FAQ
At the standard operating pressure of 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter in overall length than an equivalent ISO 15552 profile cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC250 tie-rod cylinder with matching bore, stroke, PT ports, magnet, and Viton seals.
