About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250SH
The SC200X250SH is a high-force double-acting pneumatic cylinder delivering 15708 N push and 15080 N pull at 0.5 MPa. With a 200 mm bore and 250 mm stroke, it handles heavy industrial actuation where robust tie-rod construction is essential.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and Viton (FKM) seals (-H) rated for 0 to +150 °C, making it suitable for high-temperature environments. The 40 mm rod, PT1/2 ports, and 33 mm adjustable air cushion ensure controlled deceleration of large inertial loads.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250SH Is Used
Heavy Press & Forming
Generates 28274 N of thrust at 0.9 MPa for stamping, pressing, and metal forming operations. The Viton seals withstand high radiant heat near ovens and platen presses.
Foundry & Heat Treatment
With a 0 to +150 °C operating range, this cylinder actuates dampers, gates, and clamps inside high-temperature zones, while the magnet enables hot-end position feedback.
Large Valve Actuation
Provides the high push force needed to stroke large-diameter process valves in refineries and chemical plants, with PT ports matching standard industrial piping.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250SH the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series offers 10053 N push at 0.5 MPa. If even higher force is required, step up to the 250 mm bore SC250 series delivering 24544 N at the same pressure. Always match bore, stroke, PT port thread, and the -S magnet option when replacing an existing cylinder.
At a 250 mm stroke, the 40 mm rod is well-supported within the standard stroke range, but any side loading must be managed with external guides or a guided cylinder to prevent rod bending and premature bearing wear.
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 SC200X250SH FAQ
At 0.5 MPa, 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 at 1.0 MPa is 3204 kgf.
No. The SC200X250SH is a double-acting cylinder and does not hold position when air pressure is exhausted or the valve is centered. The adjustable air cushion only decelerates the piston at stroke end. For load holding without live pressure, you must add a pilot-operated check valve or an external rod brake.
