About the Airtac SAI100 Standard Air Cylinder SAI100X125
The AirTAC SAI100X125 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 125mm stroke. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for heavy-duty pressing and lifting tasks. The extruded aluminum barrel design omits tie rods, offering a clean exterior that is dimensionally interchangeable with other ISO 15552 actuators.
This configuration utilizes a standard carbon steel piston rod and PT tapered G1/2 port threads. For environments requiring heat resistance, the standard TPU seals can be upgraded to Viton (H) components. Since no magnet is specified, position detection via CMSE or DMSE switches would require adding the -S option at order placement.

Where the Airtac SAI100 Standard Air Cylinder SAI100X125 Is Used
Heavy Pressing Operations
Provides 3927 N of thrust at 0.5 MPa for securely stamping and forming thick metal components in automated fabrication lines.
Injection Molding Ejection
Delivers reliable ejection force to remove dense plastic parts from molds, utilizing the 125mm travel to clear the tooling safely.
Pallet Lifting Stations
Raises heavy loaded pallets within distribution centers, taking advantage of the 100mm bore's high force capacity and stable ISO 15552 mounting.
Is the Airtac SAI100 Standard Air Cylinder SAI100X125 the Right Cylinder?
Choose this 100mm bore when applications demand more power than a neighboring 80mm cylinder, which yields 2513 N of push force at 0.5 MPa. The 125mm stroke is ideal for medium-travel movements without introducing significant rod deflection. For applications needing true position holding without constant air pressure, select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant, as the standard air cushion only decelerates the piston near stroke end.
To ensure a drop-in replacement, verify the 100mm bore, 125mm stroke, G1/2 port, and mounting accessory requirements (such as an FA flange or TC trunnion). If your machinery requires end-of-stroke signaling, remember to specify the -S magnet option.
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.
Airtac SAI100 Standard Air Cylinder SAI100X125 FAQ
At a 0.5 MPa operating pressure, the SAI100X125 generates a push (extend) force of 3927 N and a pull (retract) force of 3681 N. If pressure is increased to 0.7 MPa, the push force reaches 5497 N.
Yes, the SAI100X125 is a genuine ISO 15552 profile cylinder. Its mounting dimensions are interchangeable with other ISO 15552 cylinders, allowing for a seamless drop-in replacement provided the port and stroke specifications match.
