This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X160STC, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X160STC
The AirTAC Airtac SI100 Standard Cylinder SI100X160STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X160STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X160STC
The AirTAC SI100X160STC is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore, 160mm stroke, G1/2 port and TC trunnion mount. Delivering 3927 N push force at 0.5 MPa, it is replaced by the SAI100X160STC. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke, output force and porting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. Your -S magnet works with CS1-B/DS1-B switches, while SAI uses current sensors. Viton H seals raise heat to 150 C.

Where the Airtac SI100 Standard Cylinder SI100X160STC Is Used
Heavy Press Clamping
Applies the 3927 N push force at 0.5 MPa to secure large metal castings or heavy assemblies during machining and pressing operations.
Bulk Material Diversion
Leverages the 160mm stroke and TC trunnion mount to actuate heavy-duty diverter arms routing dense packages on high-throughput lines.
Replacing the Airtac SI100 Standard Cylinder SI100X160STC with the SAI100X160STC
To replace the SI100X160STC, order the SAI100X160STC. Verify the ISO 15552 TC trunnion mount, 100mm bore, 160mm stroke, G1/2 port (PT/G/NPT) and -S magnet. Sizing both ways: dropping to an 80mm bore yields 2513 N [email protected], while stepping up to 125mm provides 6136 N. A plain cylinder drifts on air loss since cushions only decelerate; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The 25mm rod and M20x1.5 thread handle high side loads. Speed is 30-800 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X160STC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X160STC FAQ
Yes, the SI100X160STC is discontinued. The direct replacement is the SAI100X160STC. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 160mm stroke, G1/2 port, TC mount and output force, so it fits existing fixtures directly.
The G1/2 port bore delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 36mm adjustable air cushion at each end.
