About the Airtac SE125 Standard Cylinder SE125X180SN
The AirTAC SE125X180SN is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. At 0.5 MPa it generates 6136 N of push force and 5734 N of pull force, scaling up to 8590 N at 0.7 MPa. The 125 mm bore operates via a PT1/2 port, driving a 32 mm rod with an M27x2 thread at speeds of 30-500 mm/s.
Unlike traditional round-body or tie-rod designs, this extruded aluminum barrel lacks external tie rods, yielding a flush, corrosion-resistant profile that mounts cleanly on automated equipment. It features field-adjustable air cushioning at both ends to decelerate heavy 1252 kgf loads smoothly. The NBR seal handles standard operating temperatures, and the built-in magnet (-S) pairs directly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.

Where the Airtac SE125 Standard Cylinder SE125X180SN Is Used
Heavy-Duty Stamping Press
Drives a heavy stamping die at 6136 N push force, using the 180 mm stroke to form thick-gauge metal components securely.
Injection Mold Clamp
Secures large injection molding halves with up to 1252 kgf holding force, utilizing the NBR seal for reliable factory air systems.
Structural Beam Straightener
Applies 8590 N of thrust at 0.7 MPa to bend or straighten structural steel beams, relying on the 32 mm rod for high side-load resistance.
Is the Airtac SE125 Standard Cylinder SE125X180SN the Right Cylinder?
This 125 mm bore cylinder provides massive thrust, but if your application requires less force you can step down to the 100 mm bore size, which yields 3927 N push at 0.5 MPa. Because 125 mm is the largest standard SE bore, stepping up requires a custom or multi-cylinder solution. The 180 mm stroke falls within standard parameters, though at this length and force class, the 32 mm rod and M27x2 thread carry significant side-load capacity; nevertheless, an external guide rail is strongly recommended to prevent rod-bearing bending under heavy off-center loads.
As a true ISO 15552 profile cylinder, it offers a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting accessories. The NBR seal suits general industrial air, while the -S magnet enables CMSE / DMSE position sensing. Remember, the adjustable air cushion only decelerates the piston near stroke end; it is not a locking mechanism, so a BSE rod lock is required if the load must be held without live air pressure.
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 SE125X180SN FAQ
This 125 mm bore cylinder provides a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. It operates at speeds of 30-500 mm/s, uses a PT1/2 port, and features a 32 mm rod with an M27x2 thread.
No. The field-adjustable air cushion at both ends only decelerates the piston near the stroke end; it is not a brake or lock. If the air is exhausted or pressure drops, the load will drift. For position holding without live pressure, you need a BSE rod lock cylinder or an external pilot-operated check valve.
