About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X125
The SC160X125 is a double-acting tie-rod cylinder with a 160 mm bore and 125 mm stroke, delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the 0.9 MPa maximum operating pressure. The 40 mm diameter piston rod and 29 mm adjustable air cushion at each end provide robust deceleration for heavy mid-stroke loads.
With a compact body length A of 239 mm, this genuine AirTAC cylinder fits installations where space is limited compared to longer ISO 15552 profiles. The PT3/4 port and M36x2 rod thread handle high flow rates, making the SC160X125 a dependable workhorse for pressing, clamping, and lifting tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X125 Is Used
Heavy Press & Clamp Fixtures
With 18095 N of force at 0.9 MPa, the SC160X125 powers pneumatic toggle clamps and assembly presses that require high force in a compact 125 mm stroke.
Pallet Stop & Lift Gates
The 40 mm rod and tie-rod construction withstand the impact of stopping heavy pallets on conveyor lines, while the adjustable cushion reduces noise and vibration.
Die Cushion & Ejection
Ideal for metal forming and stamping operations where a controlled 125 mm ejection stroke and high push force are needed to strip parts from dies.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X125 the Right Cylinder?
Choose the SC160 when the SC125's 6136 N push at 0.5 MPa is insufficient for the load. If your application needs less force, step down to the SC125 bore. For strokes of 300 mm or longer, consider an external guide or guided cylinder to protect the rod bearing from side loads.
To replace an existing unit, match five points: 160 mm bore, 125 mm stroke, PT port thread, basic (no bracket) mounting, and no magnet. This model uses the standard TPU seals for -20 to +70 C operation.
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 SC160X125 FAQ
At 0.5 MPa, push force is 10053 N and pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
This specific model code does not include the -S magnet option, so it does not have a built-in magnet. To use CMSG/DMSG/EMSG sensors, order the SC160X125-S variant which has the magnet embedded in the piston.
