Airtac SE125 Standard Cylinder SE125X220
The AirTAC Airtac SE125 Standard Cylinder SE125X220 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 220mm stroke, PT1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE125 Standard Cylinder SE125X220
The AirTAC SE125X220 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N push force at 0.5 MPa. It features a 125 mm bore, a 220 mm stroke, and a PT1/2 port. Designed without external tie rods, its extruded aluminum square barrel provides a compact, corrosion-resistant body that mounts flush against machine frames while leaving three distinct sensor grooves open for flexible switch placement.
Deceleration at high kinetic energy levels is handled by a field-adjustable air cushion at both ends, allowing technicians to tune the end-of-stroke impact rather than relying on a fixed rubber bumper. This specific SKU ships without a magnet, meaning it is not wired for CMSE or DMSE position sensing out of the box. If a job requires mid-stroke stopping or holding a load without live air pressure, this cylinder will drift, and you should look to the BSE rod-lock variant instead.

Where the Airtac SE125 Standard Cylinder SE125X220 Is Used
Automotive Stamping Press
Drives heavy lower-die clamps in an automotive stamping press, utilizing the 6136 N push force to secure 220 mm of travel in the tooling bed.
Injection Molding Ejection
Ejects dense plastic pallets from a large injection molding machine, relying on the 125 mm bore's 8590 N thrust at 0.7 MPa to break the vacuum.
Hydraulic Press Brake
Actuates the hold-down fingers on a heavy-gauge hydraulic press brake, where the tie-rod-free profile allows flush mounting into the machine bed.
Is the Airtac SE125 Standard Cylinder SE125X220 the Right Cylinder?
Choosing this 125 mm bore is appropriate when your application demands up to 6136 N of push force at 0.5 MPa (or 8590 N at 0.7 MPa). If you need slightly less thrust, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa. As the largest standard SE size, there is no larger bore to step up to within the series, so for loads exceeding the 1252 kgf maximum at 1.0 MPa, you would need to explore twin-cylinder setups or alternative mechanics.
For ISO 15552 retrofits, match the 125 mm bore, 220 mm stroke, PT1/2 port, and your required mounting accessory (such as TC centre trunnion or LB foot brackets). Because the 220 mm stroke exceeds 300 mm, be mindful of rod-bearing bending under lateral loads; an external guide rail is strongly recommended to prevent premature seal wear. Remember that the adjustable air cushion only softens the end stops and does not lock the piston in place if air pressure drops.
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 SE125X220 FAQ
The SE125X220 provides 6136 N of push force and 5734 N of pull force at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N. The maximum push force is 1252 kgf at 1.0 MPa. It operates at a speed range of 30-500 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and interface dimensions of other ISO 15552 profile cylinders. Just ensure your setup accommodates the PT1/2 port and M27x2 rod thread. Note that this specific SKU lacks a built-in magnet for CMSE/DMSE sensors.
