About the Airtac SE125 Standard Cylinder SE125X700
The AirTAC SE125X700 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 robust 125 mm bore and 700 mm stroke make it highly effective for driving large mechanisms in demanding industrial environments. Because it utilizes a square extruded aluminum barrel without external tie rods, the body is not only more compact and corrosion-resistant but also allows for flush mounting on machinery frames.
This model features a 32 mm hard-chrome plated rod and a PT1/2 port to handle high flow rates. The field-adjustable pneumatic cushioning at both ends is a true deceleration system, allowing technicians to tune the end-of-stroke dampening via a set screw to soften hard impacts when moving heavy masses at speeds up to 500 mm/s. Note that this specific SKU is built without a magnet, meaning it is not ready out-of-the-box for CMSE or DMSE electronic position sensing.

Where the Airtac SE125 Standard Cylinder SE125X700 Is Used
Automotive Press Die Handling
Leverages the 6136 N push force to shift heavy stamping dies and large structural panels into position within an automotive fabrication cell.
Heavy Metal Forming Clamp
Uses the 700 mm stroke to reach across wide workpieces, securely holding thick steel plates during an industrial bending or forming process.
Palletizer Lift Actuator
Drives the heavy lifting carriage of an end-of-line palletizer, moving loaded pallets at up to 500 mm/s with adjustable end-cushioning to soften hard stops.
Is the Airtac SE125 Standard Cylinder SE125X700 the Right Cylinder?
Selecting the SE125X700 places you at the top of the standard SE range, where the 125 mm bore yields 6136 N of push force at 0.5 MPa. If your application requires slightly less energy, stepping down to the 100 mm bore provides 3927 N of push. Conversely, if your dynamics demand the absolute maximum thrust, this is the largest standard option available, offering up to 8590 N of push at 0.7 MPa. Remember that a plain SE cylinder does not hold its position or load when air is lost or the valve is centered; the piston will drift. For load-holding requirements, consider the BSE rod lock variant or an external pilot-operated check valve.
When replacing an existing ISO 15552 cylinder, match the 125 mm bore, 700 mm stroke, PT1/2 port, and your required mounting accessory. Because this stroke extends to 700 mm, the long unsupported piston rod is susceptible to bending under side loads; always utilize an external guide to prevent premature rod-bearing wear and ensure smooth linear travel.
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 SE125X700 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 increases to 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
Yes, the SE125X700 is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting footprint, 125 mm bore, 700 mm stroke, and PT1/2 port interface. It serves as a direct drop-in replacement for other ISO 15552 profile cylinders without needing custom brackets.
