About the Airtac SE125 Standard Cylinder SE125X90S
The AirTAC SE125X90S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a substantial 6136 N push force at 0.5 MPa alongside a 5734 N pull force, making it well-suited for high-load industrial operations. The square extruded aluminum barrel omits external tie rods, yielding a corrosion-resistant body that mounts flush against machine frames while maintaining the standardized ISO 15552 mounting interface.
Equipped with a built-in magnet (-S), this unit supports direct mounting of AirTAC CMSE reed and DMSE electronic sensors along the integrated sensor grooves on three sides of the body. The field-adjustable air cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-500 mm/s cycles.

Where the Airtac SE125 Standard Cylinder SE125X90S Is Used
Palletizer Case Erector
Provides the 6136 N push force required to fold and seal heavy corrugated cardboard blanks on high-speed end-of-line palletizing machinery.
Metal Stamping Ejector
Uses the 90 mm stroke and robust 32 mm rod to positively eject thick stamped metal blanks from a press die without deflection.
Injection Mold Clamp
Secures heavy injection mold halves during material injection, utilizing the adjustable pneumatic cushion to soften the 1252 kgf clamping impact at 1.0 MPa.
Is the Airtac SE125 Standard Cylinder SE125X90S the Right Cylinder?
When sizing this 125 mm bore model, consider stepping down to the 100 mm bore variant if your application requires less energy, as it provides 3927 N push at 0.5 MPa. Since 125 mm is the largest standard SE bore available, moving further up in force requires a different series or dual-cylinder setup. For drop-in retrofits, match the 90 mm stroke, PT1/2 port, and appropriate ISO 15552 mounting accessory. Note that a plain SE cylinder relies on live air pressure to hold a load; if the valve centers or air is lost, the piston drifts. For fail-safe holding, integrate a BSE rod lock or an external pilot-operated check valve.
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 SE125X90S FAQ
This 125 mm bore cylinder generates 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa, the push force increases to 8590 N. The maximum allowable push force is 1252 kgf when operating at the 1.0 MPa pressure limit.
