This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X105H, 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 SI100X105H
The AirTAC Airtac SI100 Standard Cylinder SI100X105H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 105mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X105H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X105H
The AirTAC SI100X105H is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 105mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. The direct replacement is the SAI100X105H, matching the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
This SKU features a Viton H high-temperature seal (0 to 150C) but lacks a magnet, meaning it cannot accept a position switch. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure.

Where the Airtac SI100 Standard Cylinder SI100X105H Is Used
High-Temp Press Ejection
Handles 3927N push force to eject heavy forged parts from heated presses, utilizing the Viton H seal to withstand 150C ambient radiant heat.
Replacing the Airtac SI100 Standard Cylinder SI100X105H with the SAI100X105H
To replace the discontinued SI100X105H, order the SAI100X105H. Confirm the ISO 15552 mounting interface (LB, FA, CA, TC, etc.), the 105mm stroke, and the G1/2 port. Because this specific SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify an SAI with a magnet. For sizing alternatives, a neighbouring 80mm bore yields 2513N push at 0.5MPa, while the 125mm bore provides 6136N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X105H
- ✓ 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 SI100X105H FAQ
Yes, the SI100X105H is discontinued. The direct replacement is the SAI100X105H. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 105mm stroke, G1/2 port, and mounting interface, but features an upgraded two Y-shaped one-way piston seal for longer life and lower start-up pressure.
The G1/2 port is fixed by the 100mm bore. At 0.5MPa it provides 3927N push and 3681N pull force. At 0.7MPa push is 5497N, and at 0.9MPa it is 7068N. The theoretical maximum force is 801 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
