This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X60, 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 SI200X60
The AirTAC Airtac SI200 Standard Cylinder SI200X60 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X60
The AirTAC SI200X60 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 60mm stroke, delivering 15708 N push force at 0.5 MPa. AirTAC replaced it with the SAI200X60, a direct upgrade retaining the exact G3/4 port, M36x2 rod thread, and ISO 15552 mounting interface.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200X60 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAI200X60 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI200 Standard Cylinder SI200X60 Is Used
Heavy Stamp Pressing
Generates 21991 N at 0.7 MPa to drive heavy stamping and forming dies in automotive lines.
Large Mold Clamping
Secures oversized injection molds with a robust 15708 N push force at 0.5 MPa operating pressure.
Replacing the Airtac SI200 Standard Cylinder SI200X60 with the SAI200X60
To replace the SI200X60, order the SAI200X60 and verify the ISO 15552 mounting interface, 200mm bore, 60mm stroke, G3/4 port (PT/G/NPT thread options), and mounting accessory. If downsizing, a 160mm bore yields 10053 N push at 0.5 MPa; if upsizing is impossible, note this 200mm bore already provides 15708 N. Because this is a non-magnetized SKU, it cannot support position sensing. A plain cylinder drifts on air loss—the 50mm cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also offers the SAIF valve variant for smaller bores. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X60
- ✓ 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 SI200X60 FAQ
Yes, the SI200X60 is discontinued. The direct replacement is the SAI200X60. It shares the same ISO 15552 mounting interface, 200mm bore, 60mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 200mm bore features a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. It uses a 40mm rod with an M36x2 thread.
