About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400
The AirTAC SC160X400 is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa (18095 N at the maximum operating pressure of 0.9 MPa). With a 40 mm diameter piston rod and a 400 mm stroke, this model is built for heavy-duty linear applications requiring significant force over a moderate distance.
This cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing impact and vibration. The body length A is 239 mm, giving an approximate total extended length of 639 mm. It uses PT3/4 ports and an M36x2 rod thread for robust connections in demanding industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400 Is Used
Heavy Press & Clamping
Generates over 18000 N of clamping force at 0.9 MPa, ideal for large pneumatic presses, die-casting extractors, and heavy-duty workpiece fixturing.
Material Handling & Lifting
Provides the muscle for lifting and transferring heavy pallets, engine blocks, or steel sheets in automated material handling and logistics systems.
Industrial Gate & Damper Actuation
Operates large hopper gates, diverter chutes, and process dampers in mining, cement, and heavy processing plants where high force and reliability are critical.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400 the Right Cylinder?
For applications needing slightly less force, the SC125 series provides 6136 N push at 0.5 MPa, while the SC200 series steps up to 15708 N for the next force class. When specifying a replacement, match five key points: 160 mm bore, 400 mm stroke, PT3/4 port thread, basic mounting (no bracket), and the absence of a built-in magnet. This 400 mm stroke is well within the 1500 mm maximum standard stroke for bore 160.
For strokes of this length, ensure the load is guided and aligned axially with the rod. Any side loading can cause premature rod bearing wear or rod bending. Use an external guide rail or rod-alignment coupler if side forces are present.
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 SC160X400 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 reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not a drop-in replacement for ISO 15552 dimensions. It directly replaces another AirTAC SC tie-rod cylinder with the same 160 mm bore, 400 mm stroke, and PT3/4 ports.
