Airtac SE125 Standard Cylinder SE125X30
The AirTAC Airtac SE125 Standard Cylinder SE125X30 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 30mm 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 SE125X30
The AirTAC SE125X30 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty short-stroke actuation. Operating at 0.5 MPa, it generates 6136 N of push force and 5734 N of pull force, scaling up to a maximum push of 1252 kgf at 1.0 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific SKU is configured without a position-sensing magnet, relying on mechanical end-of-travel limits rather than CMSE or DMSE electronic switches. To absorb the high kinetic energy generated by moving large payloads at speeds up to 30-500 mm/s, the cylinder integrates field-adjustable air cushioning at both ends. Technicians can tune these cushion needles to precisely decelerate the 32 mm rod before the end cap, preventing hard mechanical impacts without locking the piston in place.

Where the Airtac SE125 Standard Cylinder SE125X30 Is Used
Heavy-Duty Stamping Press
Drives a short 30 mm stroke to apply 6136 N of clamping force at 0.5 MPa, securing heavy steel plates in an automated stamping press before the ram descends.
Injection Mold Ejection
Provides high-impact ejection force for dense injection-molded automotive parts, utilizing the 125 mm bore and adjustable end cushions to safely stop the large 32 mm rod.
Hydraulic Press Brake Hold
Acts as a robust mechanical stop in a CNC press brake, leveraging the massive 1252 kgf maximum push capability to define the exact bending depth for thick materials.
Is the Airtac SE125 Standard Cylinder SE125X30 the Right Cylinder?
Selecting the SE125X30 is appropriate when an application demands extreme clamping or holding power within a very tight 30 mm linear envelope. If you need to step the force down, the neighboring 100 mm bore yields 3927 N of push at 0.5 MPa; stepping up is not possible as 125 mm is the largest standard SE bore. Because this is a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for competing ISO 15552 cylinders, utilizing the same PT1/2 port and mounting accessories without requiring custom brackets. Remember that the adjustable air cushion only decelerates the piston near the stroke end—it does not hold the load. If your clamping fixture must maintain position safely during a sudden air loss, pair this cylinder with an external pilot-operated check valve or select the BSE rod-lock variant.
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 SE125X30 FAQ
The SE125X30 delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force increases to 8590 N, with an absolute maximum push of 1252 kgf at 1.0 MPa. The operating speed range for this 125 mm bore cylinder is 30-500 mm/s.
This specific SE125X30 SKU is built without a magnet, so it cannot host CMSE reed or DMSE electronic sensors. Additionally, while it features field-adjustable air cushions at both ends to decelerate the piston, it cannot hold a load if air pressure is lost; for position holding, consider the BSE rod-lock variant.
