About the Airtac SE125 Standard Cylinder SE125X160N
The AirTAC SE125X160N is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 6136 N push force at 0.5 MPa and a maximum of 1252 kgf at 1.0 MPa. It features a square extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while eliminating exposed rod-bearing obstructions. This specific SKU utilizes an NBR seal and a PT1/2 port.
Because this configuration lacks the built-in magnet option, it does not support AirTAC CMSE or DMSE position sensors out of the box. Deceleration at the 160 mm stroke end is handled by a field-adjustable air cushion at both ends, allowing technicians to tune the end-of-stroke deceleration via a screw rather than relying on a fixed rubber bumper.

Where the Airtac SE125 Standard Cylinder SE125X160N Is Used
Injection Mold Clamping
Provides the massive 6136 N push force required to secure heavy injection mold halves during plastic part cycles.
Stamping Press Ejection
Ejects thick-gauge stamped metal panels from press beds, utilizing the 125 mm bore's 1252 kgf max output.
Hydraulic Press Leveling
Applies high-tonnage leveling pressure to structural steel beams, relying on the NBR seal for industrial durability.
Is the Airtac SE125 Standard Cylinder SE125X160N the Right Cylinder?
Selecting this 125 mm bore provides 6136 N of push at 0.5 MPa; if your load requires less force, stepping down to the 100 mm bore yields 3927 N, while no larger standard bore exists in the SE range. Remember that a plain SE cylinder drifts when air is exhausted or valve pressure is lost, so if your application must hold a load without live pressure, consider the BSE rod-lock variant. For this 160 mm stroke, side-load stress on the M27x2 rod and bearing is minimal, but any longer unsupported stroke will require an external guide. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders using identical mounting hardware.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X160N FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force reaches 8590 N. The maximum push force is 1252 kgf when operated at 1.0 MPa.
This specific SKU lacks the built-in magnet (-S) required for AirTAC CMSE (reed) or DMSE (electronic) switches. If position sensing is needed, select an SE125 model with the S option, or utilize external limit switches.
