This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X220SN, 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 SI100X220SN
The AirTAC SI100 Standard Cylinder SI100X220SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 220mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X220SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X220SN
The AirTAC SI100X220SN is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 220 mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X220SN, sharing the exact ISO 15552 mounting interface, stroke, force and accessories. Note that 220 mm is a nonstandard stroke length.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL, SAIF and BSAI lock variants absent in the SI line. The -S magnet supports 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 SAI100X220SN 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 SI100X220SN Is Used
Heavy Press Clamping
Secures heavy metal workpieces in machining fixtures, utilizing the 3927 N push force at 0.5 MPa for rigid holding.
Package Diverters
Actuates large diverter arms on high-throughput conveyors, relying on the 3681 N pull force to reposition heavy goods.
Replacing the Airtac SI100 Standard Cylinder SI100X220SN with the SAI100X220SN
To replace the SI100X220SN, order the SAI100X220SN direct, verifying the ISO 15552 mounting interface, 100 mm bore, 220 mm nonstandard stroke, G1/2 port (PT/G/NPT thread), NBR seal and magnet (-S). If you need to adjust force, the neighboring 80 mm bore yields 2513 N push, while the 125 mm bore yields 6136 N at 0.5 MPa. Because the 220 mm stroke exceeds 300 mm, ensure adequate guide support to prevent rod bending and side loads. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X220SN
- ✓ 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 SI100X220SN FAQ
Yes, the SI100X220SN is discontinued. The direct replacement is the SAI100X220SN. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 220 mm stroke, G1/2 port, output force and mounting accessories.
This double-acting cylinder uses a G1/2 port. It generates 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. It operates at 30-800 mm/s.
