About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250
The SC160X250 is a robust double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial 10053 N of push force at a standard 0.5 MPa supply. With a 160 mm bore and a 250 mm stroke, this model features a 40 mm diameter piston rod and an M36x2 rod thread, making it suitable for heavy-duty linear applications.
This cylinder includes adjustable pneumatic cushioning at both ends, with a 29 mm cushion length to effectively decelerate high inertial loads. The body length A is 239 mm, resulting in a compact footprint for its force class. It operates on filtered air from 0.15 to 1.0 MPa and uses standard TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250 Is Used
Heavy Press & Clamping
Provides the high force needed for industrial presses, holding fixtures, and heavy-duty clamping operations in metal fabrication.
Material Handling Pushers
Ideal for pushing heavy products off a main conveyor line or transferring large pallets in automated logistics systems.
Large Valve Actuation
Operates large quarter-turn valves, dampers, or gates in process industries where high torque and reliable linear motion are critical.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250 the Right Cylinder?
Select the SC160 when your application requires a push force between roughly 10053 N and 18095 N (at 0.5-0.9 MPa). If your load is lighter, stepping down to an SC125 bore reduces the push force to 6136 N at 0.5 MPa, saving space and air consumption. For higher force demands, the SC200 bore provides 15708 N at the same pressure.
For this 250 mm stroke, ensure the load is guided and side forces are minimal; the 40 mm rod is strong, but long strokes with unguided loads can cause bending stress on the rod bearing. To replace an existing cylinder, match five points exactly: 160 mm bore, 250 mm stroke, PT3/4 port thread, basic mounting (no accessories), and the absence of a magnet.
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 AIRTAC SC125-160 Standard Cylinder SC160X250 FAQ
At 0.5 MPa, the theoretical push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N.
No. The AirTAC SC series is a tie-rod cylinder and is shorter in overall length than a standard ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC cylinder matching the 160 mm bore, 250 mm stroke, PT3/4 ports, and basic mounting.
