This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX110S, 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 SI200AX110S
The AirTAC Airtac SI200 Standard Cylinder SI200AX110S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 110mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX110S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX110S
The AirTAC SI200AX110S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 110mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this unit with the SAI200AX110S, a direct upgrade retaining the exact interface, stroke, force, and mounting. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This -A variant uses a SUS420J2 stainless piston rod for corrosion resistance, while the -S magnet supports legacy CS1-B/DS1-B sensors.
The SAI family also introduces SAIL, SAIF, and BSAI lock and valve variants absent in the legacy SI line. A plain cylinder drifts on air loss since cushions only decelerate; use a pilot check valve or SAIL lock for load holding.

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 SI200AX110S Is Used
Heavy Stamping
Drives large press dies and heavy metalforming fixtures requiring 15708 N of thrust at 0.5 MPa with stable 200mm bore guidance.
Pallet Handling
Indexes heavy loaded pallets on conveyor lines, utilizing the 110mm stroke and SUS420J2 stainless rod for wear resistance in gritty environments.
Automated Assembly
Actuates massive industrial clamps and heavy-duty robotic end effectors where a true ISO 15552 profile barrel ensures rigid mounting.
Replacing the Airtac SI200 Standard Cylinder SI200AX110S with the SAI200AX110S
To replace the discontinued SI200AX110S, order the SAI200AX110S. Confirm the ISO 15552 mounting interface, 200mm bore, 110mm stroke, G3/4 port (PT/G/NPT thread options), and your specific mounting accessory. The -A denotes a SUS420J2 stainless rod, and -S indicates a magnet for positioning switches. If sizing down, a 160mm bore yields 10053 N push at 0.5 MPa; if sizing up is impossible, this 200mm bore provides 21991 N at 0.7 MPa. For load holding on air loss, cushions only decelerate and do not lock the piston—select the SAIL or BSAI lock variant, or use an external pilot check valve. The Viton H seal option raises operating temperature to 150 C.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX110S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
