About the Airtac SE125 Standard Cylinder SE125X90
The AirTAC SE125X90 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 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 protecting internal mechanics from industrial debris.
This 125 mm bore unit operates at 30-500 mm/s and features field-adjustable air cushioning at both ends to precisely tune end-of-stroke deceleration. Note that this specific SKU lacks a built-in magnet, so it is not wired for CMSE or DMSE position sensing out of the box.

Where the Airtac SE125 Standard Cylinder SE125X90 Is Used
Injection Mold Clamping
Delivers 6136 N of thrust at 0.5 MPa to secure injection mold halves during polymer injection, utilizing the 90 mm stroke for rapid, high-force clamping cycles.
Press Fit Assembly
Drives heavy-duty mechanical pins and bushings into automotive sub-assemblies, where the 125 mm bore provides the necessary 8590 N at 0.7 MPa to overcome severe insertion resistance.
Pallet Squaring
Applies lateral pressure to square heavy loaded pallets on packaging lines before stretch wrapping, using the robust 32 mm rod to withstand high side-loading without buckling.
Is the Airtac SE125 Standard Cylinder SE125X90 the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder sits at the top of the SE range. If your application requires less force, stepping down to the 100 mm bore drops the 0.5 MPa push to 3927 N, offering a lighter, faster cycle. As the largest standard bore, there is no step up within the SE series, so exceeding 1252 kgf at 1.0 MPa requires twin cylinders or a larger bespoke actuator. Because a plain SE cylinder cannot hold a load unpowered—air loss causes the piston to drift—use a BSE rod lock variant if static holding is mandatory. For ISO 15552 retrofits, match the 90 mm stroke, PT1/2 port, and appropriate mounting accessory.
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 SE125X90 FAQ
The SE125X90 generates 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 absolute maximum push force is 1252 kgf when operating at the 1.0 MPa pressure limit.
Yes, the SE125X90 is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and PT1/2 port locations of other ISO 15552 profile cylinders. The adjustable air cushion at both ends can be tuned to match the deceleration profile of your previous actuator.
