This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X230STC, 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 SI100X230STC
The AirTAC Airtac SI100 Standard Cylinder SI100X230STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 230mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X230STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X230STC
The AirTAC SI100X230STC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 230mm stroke. It delivers 3927 N push force at 0.5 MPa. The direct replacement is the SAI100X230STC, which matches the original G1/2 port, M20x1.5 rod thread, TC trunnion mount, and ISO 15552 interface dimensions for existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X230STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X230STC Is Used
Heavy Press Clamping
Ideal for holding heavy metal components during machining, using the 3927 N push force at 0.5 MPa to secure parts firmly against the fixture bed.
Pallet Diverting
Provides robust actuation for diverting large loaded pallets on roller conveyors, with the TC trunnion absorbing pivotal moments during transit.
Replacing the Airtac SI100 Standard Cylinder SI100X230STC with the SAI100X230STC
To replace the SI100X230STC, order the SAI100X230STC. Verify the ISO 15552 TC trunnion mounting, 230mm stroke, G1/2 port (PT/G/NPT thread), and the -S magnet for CS1-B/DS1-B switches. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 6136 N. At 0.7 MPa this 100mm unit pushes 5497 N. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. The 230mm stroke is safe from buckling, but always guide side loads to protect the 25mm rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X230STC
- ✓ 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 SI100X230STC FAQ
Yes, the SI100X230STC is discontinued. The direct replacement is the SAI100X230STC. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 230mm stroke, G1/2 port, TC mounting, and output force.
The 100mm bore provides 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. Operating speed is 30-800 mm/s.
