This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X150SH, 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 SI200X150SH
The AirTAC SI200 Standard Cylinder SI200X150SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X150SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X150SH
The AirTAC SI200X150SH is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 150 mm stroke. Built for heavy-duty tasks, it yields 15708 N push and 15080 N pull at 0.5 MPa. The direct replacement is the SAI200X150SH, matching the exact G3/4 port, M36x2 thread, and ISO 15552 mounting interface. The SAI upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. This SI-SKU includes a piston magnet for CS1-B/DS1-B sensors, while the -H option specifies a Viton FKM seal rated for 0-150 C environments.
The SAI family also introduces SAIL and BSAI lock variants absent in the legacy line. Note that a standard cylinder drifts on air loss; the 50 mm adjustable cushions only decelerate near stroke ends, so use an external rod lock for holding loads.

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 SAI200X150SH 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 SI200X150SH Is Used
Heavy Stamping Press
Drives large dies and platens in metal forming, utilizing the 15708 N push force at 0.5 MPa to shape thick steel blanks reliably.
Rubber Molding Clamps
Holds industrial molds closed under high pressure. The -H Viton seal survives 0-150 C ambient heat, while the 50 mm cushions absorb heavy end-of-stroke impacts.
Pallet Lift Actuator
Raises loaded pallets in automated warehouses.
Replacing the Airtac SI200 Standard Cylinder SI200X150SH with the SAI200X150SH
To replace the discontinued SI200X150SH, order the SAI200X150SH. Verify the ISO 15552 mounting interface, 200 mm bore, 150 mm stroke, G3/4 port, and -S magnet for CS1-B/DS1-B switches. The -H suffix ensures the Viton high-temperature seal (0-150 C) is carried over. If you need to size both ways, dropping to a 160 mm bore reduces the push force to 10053 N at 0.5 MPa, while staying at 200 mm yields a massive 21991 N at 0.7 MPa. Because this plain cylinder does not hold load without live air, consider the SAIL or BSAI lock variants, or an external pilot check valve for vertical loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X150SH
- ✓ 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 SI200X150SH FAQ
Yes, the AirTAC SI200X150SH is discontinued. The direct replacement is the SAI200X150SH. It is a true ISO 15552 profile cylinder that matches the original 200 mm bore, 150 mm stroke, output force, G3/4 port, and mounting fixtures. The SAI features an upgraded piston seal for longer life.
The 200 mm bore features a G3/4 air port and an M36x2 rod thread. At 0.5 MPa it provides 15708 N push and 15080 N pull. Push force rises to 21991 N at 0.7 MPa and 28274 N at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
