This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200H, 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 SI100 Standard Cylinder SI100X200H
The AirTAC Airtac SI100 Standard Cylinder SI100X200H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X200H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X200H
The AirTAC SI100X200H is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 200 mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X200H, matching the bore, stroke, force, port, and ISO 15552 mounting interface. This SKU features a Viton H seal for 0-150 C high-temperature environments.
Because it lacks a magnet (-S), this cylinder cannot accept position sensors. The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X200H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X200H Is Used
High-Temperature Pressing
Applies 3927 N of push force at 0.5 MPa for clamping composite panels in heated molds, leveraging the Viton H seal rated for 150 C.
Replacing the Airtac SI100 Standard Cylinder SI100X200H with the SAI100X200H
To replace this SI100X200H, order the SAI100X200H. Verify the ISO 15552 mounting interface, 100 mm bore, 200 mm stroke, G1/2 port, and your specific mounting accessory. Retain the Viton H high-temperature seal for environments up to 150 C. Since this SKU lacks a magnet, it cannot support switches; if sensing is needed, specify an SAI100X200HS. The 200 mm stroke is under the 300 mm side-load threshold, but ensure axial alignment to prevent rod bending. For sizing alternatives, a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while a 125 mm bore yields 6136 N. Note that a plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X200H
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X200H FAQ
Yes, the SI100X200H is discontinued. The direct replacement is the SAI100X200H. It shares the identical ISO 15552 mounting interface, 100 mm bore, 200 mm stroke, 3927 N output force, and G1/2 port, fitting directly into existing fixtures.
The G1/2 port supplies a 30-800 mm/s speed range. Forces are 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
