About the Airtac SAI100 Standard Air Cylinder SAI100X120
The AirTAC SAI100X120 is a double-acting ISO 15552 profile cylinder engineered to deliver robust linear motion. Operating at 0.5 MPa, it generates 3927 N of push force and 3681 N of pull force, making it a powerful choice for heavy-duty machinery. The 120 mm stroke provides substantial extension for pressing, lifting, and clamping tasks.
This model features a standard carbon steel piston rod for high tensile strength and uses a PT (tapered) G1/2 port thread for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches when position feedback is required.

Where the Airtac SAI100 Standard Air Cylinder SAI100X120 Is Used
Heavy-Duty Pressing
Ideal for assembly lines requiring high downward force, utilizing the 3927 N push capability at 0.5 MPa to seat bearings and components securely.
Automated Lifting
Provides reliable vertical actuation for heavy material handling platforms, using the 120 mm stroke to elevate substantial workloads.
Pallet Clamping
Secures large pallets or workpieces in place during machining or packaging operations, ensuring zero movement under process loads.
Is the Airtac SAI100 Standard Air Cylinder SAI100X120 the Right Cylinder?
When selecting this actuator, compare its output against neighboring bores: the SAI80 provides 2513 N at 0.5 MPa, while the SAI125 offers 6136 N. The 100 mm bore is optimal when your application requires high force without stepping up to the larger 125 mm envelope. Because the stroke is 120 mm, side-load stress on the rod bearing is moderate, but external guides should still be used if the load is not perfectly axially aligned.
This SAI100X120 is dimensionally interchangeable per ISO 15552, meaning it serves as a direct drop-in replacement for other ISO 15552 profile cylinders. It features adjustable air cushions at both ends to decelerate the piston. Note that the standard cylinder does not hold position or lock the load when air pressure is lost; for fail-safe holding, consider the SAIL or BSAI variants.

- ✓ 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.
