About the Airtac SE125 Standard Cylinder SE125X100
The AirTAC SE125X100 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a robust 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while simplifying external cleaning.
This 125 mm bore unit features a substantial 32 mm piston rod and a PT1/2 port. Field-adjustable pneumatic cushioning at both stroke ends allows technicians to tune end-of-travel deceleration via a set screw, softening harsh impacts when moving massive loads at speeds up to 30-500 mm/s. This specific SKU is configured without a position-sensing magnet, relying on external limit switches for standard cycle control.

Where the Airtac SE125 Standard Cylinder SE125X100 Is Used
Injection Mold Ejection
Provides the 6136 N push force required to eject large automotive or appliance plastic parts from heavy injection molds, utilizing the adjustable cushion to soften the 100 mm stroke end-stop.
Hydraulic Press Feed
Indexing heavy steel billets into a forming press, where the high 5734 N retract force reliably pulls the substantial 32 mm rod and attached tooling back out of the work zone.
Lumber Saw Positioning
Driving the carriage of a large-scale lumber saw to set cutting depth, relying on the extruded profile barrel's flush mounting to integrate tightly into the heavy machinery frame.
Is the Airtac SE125 Standard Cylinder SE125X100 the Right Cylinder?
Generating 6136 N of push at 0.5 MPa, this model is sized for heavy loads; if your application requires slightly less force, stepping down to the 100 mm bore yields 3927 N push, whereas moving up is constrained as 125 mm is the largest standard SE bore. Because this SKU lacks the -S magnet, it cannot host internal CMSE or DMSE sensors, so position verification requires external mechanical switches. Remember that the integrated air cushion only decelerates the piston near stroke end and does not hold the load if air pressure is lost; for vertical or gravity-driven loads that must resist drifting during a pressure drop, pair this cylinder with a BSE rod lock or an external pilot-operated check valve. Additionally, while the 32 mm rod provides excellent column strength, any stroke exceeding 300 mm on this heavy bore demands an external guide rail to prevent rod-bearing bending under side loads.
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 SE125X100 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 is 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
It is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards, serving as a drop-in replacement for other ISO 15552 profile cylinders without requiring new mounting hardware. However, it does not hold its load when air is lost; the adjustable air cushion only decelerates the piston near the end of the stroke and is not a locking mechanism.
