This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X200H, 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 SI200X200H
The AirTAC SI200 Standard Cylinder SI200X200H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X200H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X200H
The AirTAC SI200X200H is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 200 mm stroke. Built for heavy loads, it delivers 15708 N push at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200X200H, matching the exact ISO 15552 mounting interface, M36x2 thread, and 50 mm cushions. This -H variant specifies Viton seals for 0-150 C environments.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. Note this SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. For load holding on air loss, specify the SAIL lock or an external pilot check valve, as cushions only decelerate.

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 SAI200X200H 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 SI200X200H Is Used
Heavy Press Clamping
Generates 21991 N at 0.7 MPa to secure large steel plates in a hydraulic press fixture before the stamping cycle begins.
High-Temperature Ejection
The Viton H seal withstands 0-150 C ambient heat, reliably ejecting molded components from hot rubber injection presses.
Replacing the Airtac SI200 Standard Cylinder SI200X200H with the SAI200X200H
To replace the SI200X200H, order the SAI200X200H. Verify the ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/4 port, and the M36x2 rod thread. Because this is a no-S SKU, it cannot accept position sensors; if sensing is needed, order the SAI equivalent with an S suffix for CS1-B/DS1-B compatibility. Sizing both ways: the 200 mm bore yields 15708 N push at 0.5 MPa (3204 kgf max at 1.0 MPa); dropping to a 160 mm bore reduces force to 10053 N. If you need positive load holding on air loss, use the SAIL air-released lock, the BSAI clamp-lock, or an external rod lock, as standard cushions only decelerate. For this 200 mm stroke, ensure guide rails carry side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X200H
- ✓ 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 SI200X200H FAQ
Yes, the SI200X200H is discontinued. The direct replacement is the SAI200X200H. It shares the identical ISO 15552 mounting interface, 200 mm bore, 200 mm stroke, G3/4 port, and output force, fitting existing fixtures perfectly while upgrading the piston seal.
The 200 mm bore uses a G3/4 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 max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
