About the Airtac SAI100 Standard Air Cylinder SAI100X155
The AirTAC SAI100X155 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. It generates 3927 N of push force and 3681 N of pull force at a 0.5 MPa operating pressure. The 155 mm stroke provides substantial extension for large format clamping and press operations. This authentic AirTAC unit features a standardized mounting interface ensuring strict dimensional interchangeability with other ISO 15552 actuators.
Beyond the standard force and stroke metrics, this configuration utilizes a robust carbon steel piston rod for high tensile strength. The extruded aluminum barrel incorporates dual sensor grooves, ready to accept CMSE or DMSE switches when a magnet is specified. Fluid supply connects via PT G1/2 tapered ports, ensuring a tight, leak-free pneumatic seal.

Where the Airtac SAI100 Standard Air Cylinder SAI100X155 Is Used
Heavy-Duty Stamping
Ideal for exerting 3927 N of thrust at 0.5 MPa to form, stamp, or rivet metal components securely.
Pallet Diversion
The 155 mm stroke provides the reach needed to push heavy pallets onto secondary processing lines.
Bulk Material Compaction
Utilizes its 100 mm bore power to compress packaging materials or industrial waste efficiently.
Is the Airtac SAI100 Standard Air Cylinder SAI100X155 the Right Cylinder?
If your application requires less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to the 125 mm bore provides 6136 N for heavier loads. The 155 mm stroke falls below the 300 mm threshold, so severe side-load bending is less of a concern, but always verify rod bearing loads. For drop-in replacements, match the 100 mm bore, 155 mm stroke, G1/2 port, and select mounting accessories like FA flanges or TC trunnions. To detect piston position, order the -S magnet option. Remember that this standard cylinder relies on live air pressure to hold position; if power fails, the load will drift. For fail-safe holding, integrate the SAIL pneumatic lock variant or an external rod lock.
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.
