About the Airtac SAI100 Standard Air Cylinder SAI100BX90S
The AirTAC SAI100X90-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making the 90 mm stroke highly effective for driving substantial clamps or heavy material handling rigs.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in washdown or humid settings. It features PT tapered ports and an integrated magnet (-S), allowing seamless mounting of CMSE or DMSE sensor switches along the dual extruded barrel grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX90S Is Used
Heavy Press Operations
Provides 3927 N of thrust at 0.5 MPa for securely stamping or pressing rigid components into housings on automated lines.
Pallet Diverter
Uses the 90 mm stroke and high lateral stability to push heavy loaded pallets onto secondary processing tracks.
Heavy Load Lift
Lifts substantial weighted containers vertically, utilizing the SUS304 rod to prevent corrosion in damp dock environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX90S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (2513 N push at 0.5 MPa) lacks the necessary thrust for your heavier fixtures. The 90 mm stroke offers a compact footprint for short, high-force movements. Because the SAI is a double-acting cylinder, it relies entirely on continuous air pressure to maintain its position; if air is removed or exhausted, the piston will drift. For applications requiring true position holding without live pressure, consider the SAIL pneumatic lock variant or an external rod lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders with matching 100 mm bore, 90 mm stroke, G1/2 port, and mounting accessory dimensions.
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 SAI100BX90S FAQ
At 0.5 MPa operating pressure, it delivers a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
No, the standard SAI cylinder does not hold position without live air pressure. For fail-safe load holding, use the SAIL (air-released lock) variant or an external rod lock.
