About the Airtac SAI100 Standard Air Cylinder SAI100X20S
The AirTAC SAI100X20-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 20mm stroke. It generates 3927 N of push force at 0.5 MPa, extending to 5497 N at 0.7 MPa. This short-stroke configuration is engineered for high-force clamping and pressing tasks where minimal travel is required. The barrel is extruded aluminum without tie-rods, providing a clean exterior.
Configured with a magnet for position sensing, this model accommodates CMSE and DMSE switches in the dual sensor grooves. The standard carbon steel piston rod ensures robust durability for heavy industrial use, while the PT tapered port threads guarantee a secure, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X20S Is Used
Heavy-Duty Stamping
Provides the massive 3927 N push force needed for short-travel metal forming and stamping operations.
Industrial Clamping
Secures large weldments or heavy machinery components firmly in place during machining and assembly.
Parts Ejection
Delivers rapid, high-impact force to eject dense finished parts from molds or heavy-duty presses.
Is the Airtac SAI100 Standard Air Cylinder SAI100X20S the Right Cylinder?
Select this 100mm bore when the 80mm variant (2513 N at 0.5 MPa) is insufficient for your heavy pressing requirements. The 20mm stroke excels in high-impact, short-travel operations. For rapid cycling at this bore size, the operational speed range is 30-800 mm/s.
Because the standard SAI is double-acting, it relies on continuous air pressure to maintain its position; if air is lost, the piston will drift. If your fixture requires failsafe load holding upon pressure drop, consider the SAIL locking variant or an external rod lock. Being a true ISO 15552 profile cylinder, it serves as a drop-in replacement matching the 100mm bore, 20mm stroke, G1/2 port, and standard mounting accessories.
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.
