About the Airtac SAI100 Standard Air Cylinder SAI100X185
The AirTAC SAI100X185 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation, delivering a robust push force of 5497 N at 0.7 MPa. Its extruded aluminum barrel eliminates tie-rods, providing a rigid yet lightweight structure. The 185 mm stroke strikes an optimal balance for mid-range extension tasks requiring substantial thrust.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. For environments where fluid contamination or temperature extremes are a concern, the standard TPU seals can be swapped for NBR or high-temperature Viton (H) options. The barrel also features dual-sided sensor grooves, allowing you to easily add CMSE or DMSE switches later by specifying the -S magnet option.

Where the Airtac SAI100 Standard Air Cylinder SAI100X185 Is Used
Heavy Stamping
Provides the necessary 5497 N of thrust at 0.7 MPa to actuate heavy-duty stamping and forming presses.
Pallet Diversion
Ideal for robust pallet routing and diverting stations where high kinetic energy demands substantial stopping power.
Material Pressing
Excels in compacting and pressing operations within automotive and heavy equipment component manufacturing.
Is the Airtac SAI100 Standard Air Cylinder SAI100X185 the Right Cylinder?
Selecting this 100 mm bore makes sense when a 80 mm cylinder falls short, as the 80 mm variant only provides 3518 N of push force at 0.7 MPa compared to the 5497 N offered here. Conversely, if your application does not require this magnitude of thrust, stepping down to a smaller bore can reduce air consumption and cycle times.
Because the 185 mm stroke is relatively short, side-load stress on the rod bearing is minimal. However, remember that standard double-acting cylinders cannot hold a load if air pressure drops; for dead-load holding, consider the SAIL variant with an air-released lock or an external pilot check valve. As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other standard profile cylinders, accepting standard FA flanges or TC trunnion mounts.
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 SAI100X185 FAQ
