About the Airtac SAI100 Standard Air Cylinder SAI100X25S
The AirTAC SAI100X25-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke automation. It provides a robust 3927 N of push force at 0.5 MPa and utilizes a G1/2 PT tapered port for optimal airflow. The 25 mm stroke is ideal for high-impact pressing and clamping tasks.
This variant includes a standard magnet for position sensing, seamlessly supporting CMSE and DMSE reed switches along the dual-sided extruded aluminum barrel groove. The piston rod is constructed from durable carbon steel, ensuring high rigidity against heavy lateral loads.

Where the Airtac SAI100 Standard Air Cylinder SAI100X25S Is Used
Short-Stroke Pressing
Delivers 3927 N of force at 0.5 MPa for stamping, riveting, and short-travel pressing operations.
Heavy-Duty Clamping
Secures large or heavy workpieces during machining, utilizing the 100 mm bore's high thrust capacity.
Product Diversion
Acts as a high-power pusher to divert heavy pallets or products on automated conveyor lines.
Is the Airtac SAI100 Standard Air Cylinder SAI100X25S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant steps the thrust up from 2513 N to 3927 N at 0.5 MPa, which is critical when your application requires heavy pressing over a very short distance. Because the 25 mm stroke is compact, side-load stress on the rod bearing is minimal compared to longer travel distances.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore ISO 15552 unit. To match this exact configuration, specify the 100 mm bore, 25 mm stroke, G1/2 port, and the -S magnet option. Note that the standard double-acting design cannot hold a load if air pressure is lost; for fail-safe holding, consider the SAIL or BSAI locking variants.
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.
