About the Airtac SE125 Standard Cylinder SE125X175CAY
The AirTAC SE125X175CAY is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N push force at 0.5 MPa. Its robust 125 mm bore and 175 mm stroke make it well-suited for high-load industrial tasks. The square extruded aluminum barrel omits external tie rods entirely, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal components.
This specific SKU is configured with a CA single clevis mounting accessory for pivoting articulation and lacks a built-in magnet, meaning it operates without electronic or reed position sensing. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration via a screw, softening hard mechanical impacts when moving massive loads at speeds up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X175CAY Is Used
Heavy Press Stamping
Provides the 8590 N extend force at 0.7 MPa necessary to drive large metal forming and stamping presses through tough material resistance.
Pivoting Lift Arm
The CA clevis mount allows articulation for heavy-duty lifting arms on automated pallet handlers, absorbing angular misalignment during load transfer.
Injection Mold Ejection
Delivers reliable 5734 N retraction force to pull heavy molded plastic parts out of deep industrial injection tooling cavities.
Is the Airtac SE125 Standard Cylinder SE125X175CAY the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder sits at the top of the SE range, making it the primary choice when the next size down—the 100 mm bore yielding 3927 N—cannot overcome machine friction or payload resistance. Because there is no larger standard SE bore, exceeding this unit's 1252 kgf maximum capacity at 1.0 MPa requires a custom or multi-cylinder solution. The CA clevis mount accommodates angular misalignment, but because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops or the valve centers; operators needing true static locking must pivot to the BSE rod-lock variant. The 175 mm stroke is well below the 300 mm threshold requiring external side-load guides, though the heavy 32 mm rod and M27x2 thread inherently handle substantial bearing loads. As a dimensionally interchangeable ISO 15552 component, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders using identical mounting hardware and PT1/2 porting.
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 SE125X175CAY FAQ
This 125 mm bore cylinder generates 6136 N of push force and 5734 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 8590 N, and it achieves a maximum push capacity of 1252 kgf at 1.0 MPa operating pressure.
It is dimensionally interchangeable per ISO 15552 standards, allowing a drop-in retrofit for other ISO 15552 profile cylinders using the same CA clevis hardware. This specific SKU lacks the -S magnet, so it does not support AirTAC CMSE or DMSE position sensors without modification.
