This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X552, 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 SI200X552
The AirTAC Airtac SI200 Standard Cylinder SI200X552 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 552mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X552, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X552
The AirTAC SI200X552 is a discontinued double-acting ISO 15552 profile cylinder. Delivering 15708 N push force at 0.5 MPa through a 200 mm bore and 552 mm stroke, it is replaced by the SAI200X552. This direct upgrade shares the exact ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. Without a magnet, this SKU cannot take a sensor. For load holding, use the SAIL or BSAI lock variants.

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 SI200X552 Is Used
Heavy Pressing
Applies up to 21991 N at 0.7 MPa for seating large bearings and forming heavy gauge metal components.
Pallet Handling
Drives robust 552 mm stroke lifts for heavy industrial pallets, requiring external guides to manage side loads.
Mold Actuation
Shifts substantial injection mold bases, utilizing the 50 mm adjustable air cushions to decelerate heavy masses.
Replacing the Airtac SI200 Standard Cylinder SI200X552 with the SAI200X552
To replace the SI200X552, order the SAI200X552, confirming the ISO 15552 mounting interface, 200 mm bore, 552 mm stroke, G3/4 port, and M36x2 thread. Sizing down, the 160 mm bore offers 10053 N push at 0.5 MPa; sizing up requires custom solutions. This non-magnet SKU cannot accept CS1-B/DS1-B sensors. A plain cylinder drifts on air loss—cushions only decelerate—so use an external rod lock or pilot check valve for holding. The 552 mm stroke demands external guides to prevent rod bending. SAIL, SAIF, and BSAI variants offer integrated locking and valve options.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X552
- ✓ 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 SI200X552 FAQ
Yes, the SI200X552 is discontinued. The direct replacement is the SAI200X552, sharing the same ISO 15552 mounting interface, 200 mm bore, 552 mm stroke, output force, and G3/4 port.
It features a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N at 0.9 MPa, and a 3204 kgf max at 1.0 MPa. Speed is 30-500 mm/s.
