About the Airtac SE125 Standard Cylinder SE125X475S
The AirTAC SE125X475S is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It delivers a substantial 6136 N push force at 0.5 MPa, utilizing a 32 mm rod and PT1/2 ports to handle heavy industrial loads. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
Because this configuration includes the -S magnet, it directly supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection. The field-adjustable air cushioning at both ends allows technicians to tune the deceleration of the 475 mm stroke via a set screw, softening hard impacts when moving massive payloads at speed.

Where the Airtac SE125 Standard Cylinder SE125X475S Is Used
Heavy Press Forming
Drives large metal stamping and bending presses where the 6136 N push force at 0.5 MPa is necessary to form thick gauge steel brackets.
Injection Mold Ejection
Ejects dense molded plastic components from heavy machinery, using the 475 mm stroke to clear the tooling envelope completely.
Pallet Lift Gates
Actuates heavy-duty industrial lift gates and diverter arms, relying on the 32 mm rod to sustain high dynamic side loading.
Is the Airtac SE125 Standard Cylinder SE125X475S the Right Cylinder?
Selecting the SE125X475S is appropriate when your application requires maximum thrust, as it provides 6136 N push at 0.5 MPa. If you need slightly less force, the next bore down is the 100 mm cylinder offering 3927 N push; stepping up is not an option as 125 mm is the largest standard SE bore. This model uses a PT1/2 port, includes the -S magnet for position sensing, and shares the standardized ISO 15552 mounting interface for seamless retrofitting.
With a 475 mm stroke, the 32 mm rod experiences significant bending moments under side loads. An external guide rail should be installed to prevent rod-bearing wear and preserve seal integrity. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not lock the load. If air pressure drops, the cylinder will drift, requiring a BSE rod lock for secure holding.
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 SE125X475S FAQ
The SE125X475S 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. The operational speed range for this 125 mm bore cylinder is 30-500 mm/s.
