This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X280SH, 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 SI200X280SH
The AirTAC SI200 Standard Cylinder SI200X280SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 280mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X280SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X280SH
The AirTAC SI200X280SH is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 280 mm stroke. Built for heavy-duty tasks, it delivers 15708 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI200X280SH, a direct upgrade retaining the exact ISO 15552 mounting interface, G3/4 port, M36x2 rod thread and 50 mm cushions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This -SH variant includes a high-temp Viton H seal (0-150 C) and a piston magnet for CS1-B/DS1-B switches. Note that standard cylinders drift without live air; use an external rod lock or SAIL/BSAI variant for load holding.

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 SAI200X280SH 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 SI200X280SH Is Used
Heavy Stamping Press
Drives large tonnage metal forming operations where the 15708 N push force at 0.5 MPa easily overcomes die resistance.
High-Temp Ejection
Utilizes the Viton H seal to reliably eject cast or hot-forged components from molds at sustained ambient temperatures up to 150 C.
Replacing the Airtac SI200 Standard Cylinder SI200X280SH with the SAI200X280SH
To replace the SI200X280SH, order the SAI200X280SH. Verify your ISO 15552 mounting fixtures (LB, FA, CA, TC), the G3/4 port, and the CS1-B/DS1-B sensor groove. The 280 mm stroke is under the 1500 mm maximum, so no side-load guide is strictly required, but always minimize rod bending. This 200 mm bore yields 15708 N at 0.5 MPa; if less force is needed, step down to a 160 mm bore (10053 N), or up if demands exceed 21991 N at 0.7 MPa. Because this is a plain cylinder, the 50 mm adjustable cushions only decelerate near stroke end—they will not hold a load on air loss. For secure holding, specify an external pilot check valve or choose the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X280SH
- ✓ 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 SI200X280SH FAQ
Yes, the AirTAC SI200X280SH is discontinued. The direct replacement is the SAI200X280SH. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 280 mm stroke, G3/4 port, and mounting hardware, but adds an upgraded two Y-shaped piston seal.
The 200 mm bore cylinder features a G3/4 air port and a 40 mm rod. It delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
