About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25
The AirTAC SC200X25 is a double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa (28274 N at 0.9 MPa), built for short-throw high-force clamping and pressing tasks. Its 25 mm stroke keeps cycle times fast while the 40 mm diameter piston rod and 33 mm adjustable air cushion handle end-of-stroke impact reliably.
With a compact body length A of 244 mm plus the 25 mm stroke, this genuine AirTAC actuator fits tight axial spaces where large-bore force is essential. The PT3/4 port and M36x2 rod thread connect directly to heavy-duty tooling, and the standard TPU seals cover a -20 to +70 °C operating window.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25 Is Used
Heavy-Duty Clamping
Short 25 mm stroke with 15708 N push force at 0.5 MPa makes the SC200X25 ideal for pneumatic clamping fixtures in welding and machining cells.
Press-Fit Assembly
Delivers controlled, repeatable force for pressing bearings, bushings, or pins into housings where a short, powerful stroke is needed.
Part Stops & Ejectors
Fast-extending 200 mm bore cylinder acts as a robust part stop or ejector on heavy-duty conveyor lines handling large castings or fabrications.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25 the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series provides 10053 N push at 0.5 MPa, while the 250 mm bore SC250 steps up to 24544 N. When replacing an existing cylinder, match bore, stroke, PT3/4 port thread, basic mounting, and confirm whether a magnet (-S) is required for sensor mounting.
Even at 25 mm stroke, the large 40 mm rod resists side load well, but if the load is not guided externally, add a linear guide or rod support to protect the bearing and seals from bending moments.
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 SC200X25 FAQ
At 0.7 MPa (7 bar) the SC200X25 produces 21991 N of push force and 15080 N of pull force, based on the 200 mm bore and 40 mm rod diameter.
This basic model (no -S suffix) does not have a built-in magnet. To use CMSG/DMSG/EMSG reed or solid-state sensors, order the SC200X25-S variant which includes a magnet ring on the piston.
