About the Airtac SE125 Standard Cylinder SE125X80S
The AirTAC SE125X80S 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 extruded aluminum square barrel omits external tie rods entirely, yielding a flush exterior that simplifies machine integration and resists mechanical snagging in tight cells.
Equipped with a built-in position magnet (-S), this 125 mm bore unit directly supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke verification. The robust Ø32 mm piston rod and M27x2 end thread handle high axial stresses, while field-adjustable air cushions at both ends absorb kinetic energy to protect payloads from harsh end-stop impacts.

Where the Airtac SE125 Standard Cylinder SE125X80S Is Used
Stamping Press Ejection
Provides the heavy 6136 N push at 0.5 MPa required to knock thick-gauge metal blanks from progressive stamping dies in a single 80 mm stroke.
Injection Mold Separation
Leverages the rigid Ø32 mm rod to break the vacuum seal on large injection molding tools, safely pulling heavy rear mold halves apart.
Structural Beam Straightening
Applies up to 1252 kgf of pressing force to correct warpage in thick-walled aluminum extrusions during aerospace assembly operations.
Is the Airtac SE125 Standard Cylinder SE125X80S the Right Cylinder?
Selecting this 125 mm bore cylinder makes sense when your application requires maximum thrust, pushing 6136 N at 0.5 MPa. If you need slightly less force, stepping down to the 100 mm bore drops the 0.5 MPa push to 3927 N, whereas this SE125X80S represents the top standard capacity in the series with no larger neighbor. Because the 80 mm stroke is relatively short for this massive bore, side-load bending on the rod bearing is minimal, though external guides remain best practice for offset loads. Remember that the adjustable air cushion only decelerates the piston near stroke end and does not lock the rod; if air pressure drops, the load will drift unless you pair it with a BSE rod lock variant. For drop-in retrofits, ensure your existing ISO 15552 mounting hardware and PT1/2 port threads match this footprint.
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 SE125X80S 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 reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. Its operating speed ranges from 30-500 mm/s.
