About the Airtac SE125 Standard Cylinder SE125X330S
The AirTAC SE125X330S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty motion. It delivers a substantial 6136 N push force at 0.5 MPa and utilizes a PT1/2 port paired with a robust Ø32 mm rod. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This 125 mm bore unit includes a built-in magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration, softening hard impacts when moving heavy loads at speeds up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X330S Is Used
Injection Mold Clamping
Provides massive 6136 N push force at 0.5 MPa to secure heavy injection mold halves during press operations.
Automotive Press Ejection
Utilizes the 330 mm stroke and Ø32 mm rod to eject stamped metal body panels from large mechanical presses.
Heavy Metal Forming
Applies up to 1252 kgf at 1.0 MPa for bending and straightening thick steel structural components.
Is the Airtac SE125 Standard Cylinder SE125X330S the Right Cylinder?
This 125 mm bore generates 6136 N push at 0.5 MPa; if your application requires less force, stepping down to the 80 mm bore yields 2513 N, while the largest standard bore in this range means there is no larger step-up within the SE series. At 330 mm of stroke, the unsupported piston rod is highly susceptible to bending under side loads—always incorporate an external linear guide to prevent rod-bearing damage. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, sharing standard mounting and PT port hardware. Note that the air cushion only decelerates the piston near stroke end; it does not hold the load. If unpowered drift is unacceptable, specify a BSE rod lock.
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 SE125X330S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force is 8590 N. The maximum push force is 1252 kgf when operating at the 1.0 MPa pressure limit.
No, the field-adjustable air cushion at both ends only decelerates the piston near the stroke end and is not a locking mechanism. If you need to hold a load without live air pressure, you must use a BSE rod lock variant or an external pilot-operated check valve.
