This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X220, 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 SI200 Standard Cylinder SI200X220
The AirTAC Airtac SI200 Standard Cylinder SI200X220 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 220mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X220, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X220
The AirTAC SI200X220 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 220 mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X220 direct. This SKU lacks a magnet and cannot accept a sensor.
The SAI upgrade retains the exact ISO 15552 mounting interface but uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. The SAI family also adds SAIL and BSAI lock variants absent from the SI line.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200X220 Is Used
Heavy Press Operations
Drives large forming and stamping presses requiring up to 15708 N of thrust at 0.5 MPa with stable ISO 15552 fixture integration.
Automated Assembly Lines
Shifts heavy structural components along production lines, utilizing the 50 mm adjustable air cushions to decelerate massive loads.
Replacing the Airtac SI200 Standard Cylinder SI200X220 with the SAI200X220
To replace the SI200X220, order the SAI200X220 keeping the identical 200 mm bore, 220 mm stroke, G3/4 port, and ISO 15552 mounting. If you need load holding on air loss, note that this plain cylinder drifts; the cushion only decelerates. Specify the SAIL or BSAI lock variant, or use an external rod lock. For sizing, the neighbouring 160 mm bore yields 10053 N at 0.5 MPa, while this 200 mm bore reaches 21991 N at 0.7 MPa. Since the 220 mm stroke is over 300 mm, ensure guide elements to prevent rod bending under side loads. This non-magnet SKU cannot use CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X220
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200X220 FAQ
Yes, the SI200X220 is discontinued. The direct replacement is the SAI200X220. It shares the identical ISO 15552 mounting interface, 200 mm bore, 220 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
This double-acting cylinder features a G3/4 port and delivers 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa it pushes 21991 N, and 28274 N at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
