Airtac SE125 Standard Cylinder SE125X190S
The AirTAC Airtac SE125 Standard Cylinder SE125X190S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 190mm stroke, PT1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE125 Standard Cylinder SE125X190S
The AirTAC SE125X190S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, 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 standardized mounting interfaces for seamless retrofitting. This 125 mm bore unit is equipped with a built-in magnet (-S) designed to interface directly with AirTAC CMSE reed and DMSE electronic position sensors along its three integrated sensor grooves.
To manage the significant kinetic energy of a 125 mm piston traveling at up to 500 mm/s, this model incorporates field-adjustable air cushions at both stroke ends. Rather than a fixed rubber bumper, technicians can tune the cushion needle valves to precisely decelerate the load, eliminating hard end-stop impacts. Note that while these cushions soften travel, they are not locking mechanisms; if the air supply is lost, the piston will drift unless held by an external guide or a BSE rod-lock variant.

Where the Airtac SE125 Standard Cylinder SE125X190S Is Used
Heavy Press Stamping
Drives large metal forming and stamping presses where the 6136 N push force at 0.5 MPa is required to bend thick sheet metal components securely.
Injection Mold Clamping
Actuates heavy mold halve closures in plastic injection machinery, relying on the 125 mm bore's robust 1252 kgf max thrust and adjustable end cushions.
Pallet Ejection Systems
Pushes loaded pallets off high-capacity roller conveyors in distribution hubs, utilizing the 190 mm stroke and stable no-tie-rod profile for flush mounting.
Is the Airtac SE125 Standard Cylinder SE125X190S the Right Cylinder?
Selecting the SE125X190S is appropriate when your application demands the maximum standard thrust in the AirTAC line, generating 6136 N of push force at 0.5 MPa. If your load requirement is lighter, stepping down to the 100 mm bore reduces the footprint and yields 3927 N of push force at 0.5 MPa. Because this is the largest standard bore, there is no larger step-up within the SE range; for higher forces, consider deploying two cylinders in tandem. The PT1/2 porting and M27x2 rod thread match the 125 mm bore standard, and the included -S magnet enables CMSE or DMSE sensor integration. For any stroke length of 300 mm or more, the extended unsupported piston rod is susceptible to bending under side loads; always pair long strokes with an external linear guide to prevent rod-bearing damage.
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 SE125X190S FAQ
At 0.5 MPa, the SE125X190S 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. It operates at pressures from 0.15-1.0 MPa with a speed range of 30-500 mm/s.
No, the SE125X190S is a standard double-acting cylinder and will drift if air is lost or the valve is centered. The adjustable air cushions only decelerate the piston near stroke ends; they do not lock the load. For fail-safe position holding, consider the AirTAC BSE series with a dedicated rod lock.
