This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X210SH, 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 SI100X210SH
The AirTAC Airtac SI100 Standard Cylinder SI100X210SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 210mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X210SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X210SH
The AirTAC SI100X210SH is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 210 mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X210SH, matching the exact mounting interface, stroke and force.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This -H variant uses Viton seals for 0-150 C environments, and the -S magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X210SH Is Used
Heavy Press Clamping
Secures large metal workpieces in machining fixtures, utilizing the 3927 N push force at 0.5 MPa for rigid, high-tonnage holding.
Pallet Lift Stations
Drives vertical lifting arms for heavy goods.
High-Tact Forming
Performs hot-stamping or forming operations, where the Viton H seal option sustains 0-150 C ambient temperatures without degrading.
Replacing the Airtac SI100 Standard Cylinder SI100X210SH with the SAI100X210SH
To replace the SI100X210SH, order the SAI100X210SH. Confirm the ISO 15552 mounting fixture, 100 mm bore, 210 mm stroke, G1/2 port (PT/G/NPT thread) and the -S magnet. This 210 mm stroke is nonstandard but mechanically valid; for any stroke over 300 mm, add external guides to prevent rod bending under side loads. If sizing down, an 80 mm bore yields 2513 N push at 0.5 MPa; sizing up to 125 mm gives 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For held loads, use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant integrates a 4M valve for bores up to 100 mm.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X210SH
- ✓ 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 SI100X210SH FAQ
Yes, the SI100X210SH is discontinued. The direct replacement is the SAI100X210SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 210 mm stroke, output force, G1/2 port and mounting interface.
The bore is 100 mm with a G1/2 air port. Force ratings are: 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 theoretical maximum of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
