This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X150H, 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 SI100X150H
The AirTAC Airtac SI100 Standard Cylinder SI100X150H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X150H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X150H
The AirTAC SI100X150H is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 150mm stroke. Delivering 3927N push force at 0.5MPa, it features a G1/2 port, M20x1.5 rod thread, and a high-temp Viton H seal rated for 0-150C. This SKU lacks a magnet, so it cannot accept a sensor. AirTAC replaced it with the SAI100X150H.
The SAI100X150H is a direct replacement matching the exact ISO 15552 mounting interface, bore, stroke, force, and port. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure. For load holding, note that cushions only decelerate; use a SAIL lock or external pilot check valve.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X150H carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI100X150H 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 SI100X150H Is Used
High-Tact Molding
Operates reliably in 0-150C environments using the Viton H seal to actuate heavy mold halves.
Pallet Diverting
Shifts heavy pallets laterally using the robust 25mm rod and adjustable 36mm end cushions.
Replacing the Airtac SI100 Standard Cylinder SI100X150H with the SAI100X150H
To replace the SI100X150H, order the SAI100X150H. Confirm the ISO 15552 mounting interface, 100mm bore, 150mm stroke, G1/2 port, and Viton H high-temperature seal. This non-magnetic SKU cannot take a switch. For sizing, the 100mm bore yields 3927N push at 0.5MPa; dropping to an 80mm bore gives 2513N, while a 125mm bore provides 6136N. A plain cylinder drifts on air loss since cushions only decelerate; for load holding, select the SAIL or BSAI lock variant, or an external rod lock. The SAI family also adds the SAIF self-valve option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X150H
- ✓ 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 SI100X150H FAQ
Yes, the SI100X150H is discontinued. The direct replacement is the SAI100X150H, which shares the same ISO 15552 mounting interface, 100mm bore, 150mm stroke, force, and G1/2 port.
It features a G1/2 port. Force ratings are 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa.
