About the Airtac SAI100 Standard Air Cylinder SAI100X90S
The AirTAC SAI100X90-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a push force of 3927 N at 0.5 MPa, this 100mm bore unit paired with a 90mm stroke excels in high-thrust operations. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior that resists contamination while maintaining strict ISO mounting dimensions.
This specific configuration includes a magnetic piston for use with CMSE and DMSE reed switches, fitting neatly into the dual sensor grooves on the barrel. It utilizes a standard carbon steel piston rod and features adjustable air cushions at both ends to decelerate the payload smoothly. The fluid porting uses a PT tapered thread configuration for secure, leak-free pneumatic connections.

Where the Airtac SAI100 Standard Air Cylinder SAI100X90S Is Used
Heavy Stamping
Provides the robust 3927 N push force required to actuate large mechanical presses and form rigid metal components securely.
Pallet Diverters
Drives heavy-duty diverter arms on automated conveyor lines, using the magnetic piston and sensors to confirm stroke position.
Clamping Fixtures
Holds large workpieces stationary during CNC machining or welding operations, utilizing the 90mm stroke for rapid clamping.
Is the Airtac SAI100 Standard Air Cylinder SAI100X90S the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when an 80mm bore (2513 N push at 0.5 MPa) lacks the necessary thrust for moving substantial masses. If the 90mm stroke is slightly excessive for a compact machine layout, dropping to a 50mm bore (982 N) saves space but sacrifices significant power. Because this is a standard 90mm stroke, side-load stress on the rod bearing is minimal compared to longer travel variants.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard ISO 15552 interface, matching bore, stroke, PT G1/2 port, and mounting accessory dimensions. Remember that the adjustable cushions only decelerate the piston at stroke ends; they do not lock the rod. If your machinery loses air pressure and needs to hold a load vertically, integrate an external pilot-operated check valve or specify the SAIL locking variant.
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 SAI100X90S FAQ
At a standard 0.5 MPa operating pressure, the SAI100X90-S generates a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force reaches 5497 N.
Yes, the SAI100X90-S is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting interface, 100mm bore, 90mm stroke, and G1/2 port dimensions as other ISO 15552 profile cylinders, allowing for direct drop-in replacement.
