Airtac SE125 Standard Cylinder SE125X35
The AirTAC Airtac SE125 Standard Cylinder SE125X35 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 35mm 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 SE125X35
The AirTAC SE125X35 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N of push force at 0.5 MPa. Its square extruded aluminum barrel completely eliminates external tie rods, yielding a smooth, flush exterior that resists contamination and simplifies direct mounting. This robust 125 mm bore unit utilizes a 32 mm rod and a PT1/2 port to efficiently handle high-flow pneumatic demands.
Field-adjustable air cushioning at both stroke ends allows technicians to precisely tune end-of-stroke deceleration, preventing harsh impacts when moving heavy masses. This specific SKU is configured without a magnet, meaning it is not equipped for CMSE or DMSE position sensing out of the box. If a job requires positive load holding upon air loss, this standard cylinder will drift and must be paired with a BSE rod lock variant.

Where the Airtac SE125 Standard Cylinder SE125X35 Is Used
Injection Mold Clamping
Provides intense 6136 N clamping pressure at 0.5 MPa to secure heavy injection mold halves during plastic part ejection cycles.
Punch Press Feeder
Handles the high-force, short-stroke indexing required to push thick metal sheet stock into heavy-duty punch presses safely.
Hydraulic Press Ejector
Uses its full 8590 N push at 0.7 MPa to positively eject dense forged components from hydraulic press dies.
Is the Airtac SE125 Standard Cylinder SE125X35 the Right Cylinder?
Selecting the SE125X35 makes sense when your application requires the maximum standard thrust in the AirTAC ISO 15552 range, peaking at 1252 kgf at 1.0 MPa. If you need slightly less force, stepping down to the 100 mm bore yields a 3927 N push at 0.5 MPa; as the largest standard size, there is no larger bore neighbour in this series. Because this is a 35 mm stroke, the 32 mm rod and M27x2 thread easily support the load without requiring an external guide. For retrofitting, this model is dimensionally interchangeable with any true ISO 15552 cylinder, matching the 125 mm bore footprint, 35 mm stroke, PT1/2 port, and basic mounting interface.
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 SE125X35 FAQ
The SE125X35 generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum push of 1252 kgf at 1.0 MPa. Its operating speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable with standard ISO 15552 mounting interfaces. However, this specific SKU lacks the built-in magnet (-S), so it cannot support CMSE or DMSE sensors without modifying the piston assembly.
