This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X925N, 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 SI100X925N
The AirTAC Airtac SI100 Standard Cylinder SI100X925N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 925mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X925N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X925N
The AirTAC SI100X925N is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 925mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa through a G1/2 port. The direct replacement is the SAI100X925N, which shares identical mounting, force, and interface dimensions. This non-magnetic SKU lacks a sensor groove switch and cannot take a sensor. The NBR seal supports -20 to +70C, with a Viton H option available for high heat.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. For load holding, note that a plain cylinder drifts on air loss; the cushion only decelerates. Use an external rod lock or the SAIL/BSAI lock variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X925N 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 SAI100X925N 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 SI100X925N Is Used
Heavy Press Clamping
Provides 3927N of clamping force at 0.5MPa for securing heavy steel plates during machining or welding operations.
Pallet Diversion
Uses the 925mm stroke to push heavy pallets sideways onto branching conveyor lanes in high-throughput logistics hubs.
Replacing the Airtac SI100 Standard Cylinder SI100X925N with the SAI100X925N
To replace the SI100X925N, order the SAI100X925N. Confirm the ISO 15552 interface, 100mm bore, 925mm stroke, G1/2 port (PT/G/NPT), and NBR seal. Because this is a non-S SKU, it cannot accept a CS1-B/DS1-B sensor. For sizing, a 100mm bore yields 3927N push at 0.5MPa; dropping to an 80mm bore gives 2513N, while a 125mm bore yields 6136N. With a 925mm stroke, prevent rod bending by adding external guides to manage side loads. A plain cylinder does not hold load without air; use a pilot check valve or the SAIL/BSAI lock variant for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X925N
- ✓ 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 SI100X925N FAQ
Yes, the AirTAC SI100X925N is discontinued. The direct replacement is the SAI100X925N. It is dimensionally interchangeable per ISO 15552, offering the same 100mm bore, 925mm stroke, output force, G1/2 port, and mounting interface, but features an upgraded two Y-shaped piston seal for lower start-up pressure.
This 100mm bore double-acting cylinder uses a G1/2 air port and an M20x1.5 rod thread. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum force of 801kgf at 1.0MPa. The adjustable air cushion is 36mm at each end.
