This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1295, 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 SI200X1295
The AirTAC SI200 Standard Cylinder SI200X1295 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1295mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1295, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X1295
The AirTAC SI200X1295 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 1295 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200X1295, a direct sharing the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure.
Because this SKU lacks the -S magnet, it cannot accept a position sensor. For load holding, note that standard cushions only decelerate; you need an external pilot check valve or the SAIL lock variant to prevent drift.

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 SAI200X1295 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 SI200X1295 Is Used
Heavy Press Forming
Applies the 21991 N push force at 0.7 MPa to form heavy-gauge metal components and stamp large industrial assemblies.
Pallet Lift Stations
Raises loaded pallets up to the 801 kg vertical lift capacity, relying on external guides to manage the 1295 mm stroke safely.
Bulk Material Diversion
Shifts heavy bulk material flows on high-capacity conveyor lines, using the 50 mm adjustable cushions to decelerate massive loads.
Replacing the Airtac SI200 Standard Cylinder SI200X1295 with the SAI200X1295
To replace the SI200X1295, order the SAI200X1295. Confirm the ISO 15552 mounting accessory (LB foot, FA flange, or TC trunnion) and the G3/4 port match your fixture. Since this is a non-magnet SKU, it cannot support CS1-B/DS1-B sensors; add the -S suffix if you need position detection. Sizing both ways: the 200 mm bore yields 15708 N push at 0.5 MPa (3204 kgf max at 1.0 MPa), while a neighboring 160 mm bore provides 10053 N. For this 1295 mm stroke, external guides are strongly recommended to prevent rod bending and excessive side loads. If you need static holding without air, use the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X1295
- ✓ 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 SI200X1295 FAQ
Yes, the AirTAC SI200X1295 is discontinued. The direct replacement is the SAI200X1295. It shares the same ISO 15552 mounting interface, 200 mm bore, 1295 mm stroke, output force, G3/4 port, and accessories, fitting directly into existing fixtures.
This double-acting cylinder uses a G3/4 air port. It generates 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical maximum of 3204 kgf at 1.0 MPa. It operates at 30-500 mm/s.
