About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200
The SC160X1200 is a double-acting tie-rod cylinder delivering substantial linear force, with a push thrust of 10053 N at 0.5 MPa and reaching 18095 N at the maximum operating pressure of 0.9 MPa. This model features a 1200 mm stroke, well within the 1500 mm maximum standard stroke for the 160 mm bore, and uses a robust 40 mm diameter piston rod with an M36x2 knuckle thread.
With a body length A of 239 mm, the total extended length is approximately 1439 mm. The cylinder includes an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston and reduce end-of-stroke impact. It operates on filtered air (40 µm) at 0.15-1.0 MPa and is fitted with standard PT ports (PT3/4) and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200 Is Used
Heavy Machinery Actuation
Operates large levers, gates, and chutes on construction and agricultural equipment where a high-force, long-stroke pneumatic cylinder is needed for robust, repetitive movements.
Pallet and Product Pushers
Provides the long 1200 mm reach and high force required to push heavy pallets, crates, or large products off a conveyor line onto a secondary handling or wrapping station.
Wastewater Screen Cleaning
Drives a long-stroke linear actuator for cleaning rakes on bar screens in water treatment plants, reliably handling the wet, dirty environment with a force of over 10,000 N.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200 the Right Cylinder?
This SC160X1200 model provides 10053 N of push force at 0.5 MPa, making it a powerful choice for heavy linear actuation. If your application requires less force, consider stepping down to the SC125 series, which offers 6136 N at the same pressure. For even higher force demands, the SC200 series delivers 15708 N at 0.5 MPa. Always ensure the bore and stroke match your load requirements.
For this 1200 mm stroke, managing side loads is critical to prevent rod bending and premature bearing wear. An unsupported long stroke is vulnerable to buckling under compressive loads or deflection from lateral forces. It is highly recommended to use an external guide system or a guided cylinder to absorb side loads, ensuring the piston rod is subjected only to axial forces. For a direct replacement, match five key points: 160 mm bore, 1200 mm stroke, PT3/4 port thread, basic mounting, 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 SC160X1200 FAQ
At the standard 0.5 MPa operating pressure, the 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. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a standard ISO 15552 cylinder, so it is not dimensionally interchangeable. It can only directly replace another AirTAC SC tie-rod cylinder with the same 160 mm bore, 1200 mm stroke, PT3/4 port, and basic mounting configuration.
