About the Airtac SE125 Standard Cylinder SE125X130S
The AirTAC SE125X130S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a robust 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a highly compact, corrosion-resistant body that mounts flush against machine frames while maintaining the standardized ISO 15552 footprint for seamless retrofitting.
Equipped with a built-in magnet (-S), this 125 mm bore unit seamlessly interfaces with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable air cushioning at both ends allows technicians to dial in deceleration via a set screw, softening hard mechanical stops for the massive 1252 kgf maximum load without relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125X130S Is Used
Plastic Injection Mold Clamping
Provides the 6136 N push force required to secure heavy injection mold halves against high-pressure resin injection, utilizing the adjustable cushion to protect expensive tooling at stroke end.
Metal Stamping Press
Drives small progressive-die stamping operations with up to 8590 N thrust at 0.7 MPa, where the rigid 32 mm rod and M27x2 thread endure high mechanical stress and side loading.
Heavy Door Manipulation
Automates large industrial blast furnace doors or heavy hydraulic press safety guards, relying on the 1252 kgf maximum capacity and CMSE/DMSE sensor feedback for safe operation.
Is the Airtac SE125 Standard Cylinder SE125X130S the Right Cylinder?
Stepping down from this 125 mm bore (6136 N push @0.5 MPa), the 100 mm neighbor provides 3927 N push, suitable if your application is over-specified. Stepping up is not an option as this is the largest standard SE bore, making the SE125X130S the definitive choice for maximum thrust. Since this is a plain double-acting cylinder, it cannot hold a load if air pressure drops; for vertical positioning safety, consider the BSE rod lock variant. For the 130 mm stroke, side-load is moderate, but always verify rod-bearing bending loads and use an external guide if heavy lateral forces are present. To match: 125 mm bore, 130 mm stroke, PT1/2 port, basic mounting, and -S magnet.
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 SE125X130S FAQ
