About the Airtac SE125 Standard Cylinder SE125X600S
The AirTAC SE125X600S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, 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 exposing the standardized ISO 15552 mounting interface for seamless retrofits.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic position sensors along the three integrated sensor grooves. The field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when moving heavy loads across the 600 mm span.

Where the Airtac SE125 Standard Cylinder SE125X600S Is Used
Automotive Press Loading
Pushes heavy sheet metal blanks into staging presses using the 6136 N extend force, while the 600 mm stroke accommodates wide conveyor offsets.
Pallet Dispenser Actuation
Lifts and separates empty wooden pallets in high-throughput packaging lines, relying on the 125 mm bore to overcome guide friction and pallet weight.
Injection Mold Ejection
Drives large mold ejection plates where the 32 mm rod and M27x2 thread provide the structural rigidity needed to extract bulky plastic parts safely.
Is the Airtac SE125 Standard Cylinder SE125X600S the Right Cylinder?
Generating 6136 N of push at 0.5 MPa, this 125 mm bore is the largest in the SE range, so if you need to step down, the 100 mm bore provides 3927 N of push at 0.5 MPa. Because this cylinder uses a 600 mm stroke, the 32 mm rod and M27x2 thread must handle significant bending moments; an external guide is recommended to prevent side-load damage to the rod bearing. The PT1/2 port matches the bore's high flow requirements, and the -S magnet enables precise end-position feedback. Note that the adjustable air cushion only decelerates the piston near stroke end—it will not hold a load if air pressure is lost, so a BSE rod lock is required for fail-safe 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 SE125X600S FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X600S is dimensionally interchangeable with other ISO 15552 profile cylinders, sharing standard mounting footprints and PT1/2 ports. However, it cannot hold a load if air is lost; the adjustable cushion only decelerates the piston near the end stops, so a BSE rod lock variant is needed for position holding.
