About the Airtac SE125 Standard Cylinder SE125X160SCB
The AirTAC SE125X160SCB is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while simplifying external accessory attachment.
Equipped with a built-in magnet for CMSE and DMSE position sensing, this 125 mm bore unit utilizes a double clevis (CB) mounting style for pivoting articulation. The field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, precisely absorbing kinetic energy from the 32 mm rod to prevent hard mechanical impacts.

Where the Airtac SE125 Standard Cylinder SE125X160SCB Is Used
Stamping Press Ejection
Provides the high 6136 N push force required to knock heavy stamped metal panels out of progressive die sets, utilizing the 160 mm stroke to clear the lower die bed completely.
Injection Mold Separation
Leverages the CB double clevis mount to articulate smoothly while breaking the vacuum seal on large plastic injection molds, pulling with 5734 N of retract force at 0.5 MPa.
Pallet Stopper Arms
Acts as a heavy-duty pivoting stop gate on high-mass pallet conveyors, using the integrated magnet to trigger DMSE sensors and confirm the arm is fully deployed before indexing.
Is the Airtac SE125 Standard Cylinder SE125X160SCB the Right Cylinder?
Selecting this 125 mm bore cylinder is appropriate when your application requires up to 6136 N of push at 0.5 MPa. If your load demands less force, stepping down to the 100 mm bore yields 3927 N of push, whereas this SE125X160SCB represents the maximum standard profile bore available before moving to specialized large-bore custom units.
Because this is a plain double-acting cylinder, it will drift if air pressure is lost or the valve is centered; applications requiring strict load holding without live pressure should integrate an external pilot-operated check valve or explore the BSE rod-lock variant. This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders using the same 160 mm stroke, PT1/2 port, and CB clevis 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 SE125X160SCB FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
No, the adjustable air cushion at the ends only decelerates the piston near stroke end and does not act as a brake. If air is lost, the piston will drift. For position holding under load, you need a BSE rod lock cylinder or an external pilot-operated check valve.
