This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X80H, 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 SI200X80H
The AirTAC SI200 Standard Cylinder SI200X80H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X80H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X80H
The AirTAC SI200X80H is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke and a high-temperature Viton H seal. Built for heavy-duty cycles, it delivers 15708 N push and 15080 N pull at 0.5 MPa, operating at 30-500 mm/s through a G3/4 port. Because this SI series is end-of-life, AirTAC supplies the exact SAI200X80H direct replacement. It matches the bore, stroke, force, M36x2 rod thread and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features a revised piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. This SKU lacks the -S magnet, so it cannot accept CS1-B or DS1-B sensors. Note that a standard cylinder drifts on air loss; for secure holding, specify an external pilot check valve or the SAIL/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 SI200X80H Is Used
Heavy Stamp Pressing
Drives large forming dies with 21991 N of push force at 0.7 MPa, utilizing the robust 40 mm rod to maintain rigidity under high impact loads.
Foundry Actuation
Operates reliably in hot environments up to 150 C using the Viton H seal, shifting heavy cast components or furnace doors over the 80 mm stroke.
Replacing the Airtac SI200 Standard Cylinder SI200X80H with the SAI200X80H
To replace the discontinued SI200X80H, order the SAI200X80H. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the 80 mm stroke, and the G3/4 port. This unit uses a Viton H seal rated for 0-150 C, and because it has no -S magnet, switch sensing is impossible. The 40 mm rod and M36x2 thread must align with your mechanics. If you need less force, step down to the 160 mm bore (10053 N push); if holding the load without live air is required, use an external rod lock or the SAIL lock variant, as the 50 mm cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X80H
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
