About the Airtac SAI125 Standard Air Cylinder SAI125X80
The AirTAC SAI125X80 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, providing a robust push force of 6136 N and a pull force of 5734 N at 0.5 MPa. Featuring an 80 mm stroke, this extruded aluminum barrel design eliminates tie-rods for a sleeker profile while maintaining strict dimensional interchangeability with other ISO 15552 mounting interface actuators.
This specific configuration ships with a standard carbon steel piston rod and PT tapered port threads (G1/2). Because it lacks the -S magnet option, it is optimized purely for mechanical actuation rather than electronic position sensing, though the barrel retains dual-side sensor grooves should your application later require CMSE or DMSE switches.

Where the Airtac SAI125 Standard Air Cylinder SAI125X80 Is Used
Heavy Stamping Press
Provides 6136 N of extension force at 0.5 MPa to actuate heavy-duty stamping and forming dies in metal fabrication facilities.
Automotive Assembly Jig
Drives robust positioning arms and heavy structural clamps on automotive welding lines where high kinetic output is required.
Pallet Diverting Gate
Powers heavy-duty mechanical diverters and sorting gates on high-mass pallet conveyor systems handling industrial goods.
Is the Airtac SAI125 Standard Air Cylinder SAI125X80 the Right Cylinder?
Selecting this 125 mm bore is ideal when a 100 mm bore (delivering 3927 N push at 0.5 MPa) is insufficient, but a larger 160 mm bore (10053 N) would be physically oversized. The 80 mm stroke provides rapid, short-travel linear movement. For applications requiring multi-directional clamping without continuous live air pressure, consider the BSAI bidirectional clamp-lock variant, as the standard SAI125X80 will drift if air pressure is lost.
When ordering, verify your requirements for the G1/2 port, M27x2 rod thread, and the 40 mm adjustable cushion stroke at both ends. Operating speed ranges from 30-500 mm/s, making it suitable for moderately paced industrial cycles.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
