This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX160, 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 SI100AX160
The AirTAC Airtac SI100 Standard Cylinder SI100AX160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX160
The AirTAC SI100AX160 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 160mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 801 kgf. AirTAC replaced this legacy unit with the SAI100AX160, a direct sharing the identical G1/2 port, M20x1.5 rod thread, and ISO 15552 mounting interface.
This specific SKU features a SUS420J2 stainless steel rod for corrosion resistance but lacks a magnet, so it cannot accept position switches. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. For load holding, note that standard cylinders drift without live air; use an external pilot check valve or the SAIL/BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100AX160 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 SAI100AX160 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 SI100AX160 Is Used
Heavy-Duty Pressing
Applies up to 7068 N of thrust at 0.9 MPa for seating bearings, stamping light-gauge sheet metal, or clinching components in automated fabrication cells.
Pallet Diverting
Handles robust diverting or stopping tasks on heavy material handling lines, using the adjustable 36mm air cushions to decelerate high kinetic energy loads smoothly.
Replacing the Airtac SI100 Standard Cylinder SI100AX160 with the SAI100AX160
To replace the SI100AX160, order the SAI100AX160. Confirm the ISO 15552 mounting interface, the 100mm bore, 160mm stroke, and G1/2 port. Because this SKU has no -S suffix, it lacks a magnet and cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is needed. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 6136 N. At 0.7 MPa this 100mm unit pushes 5497 N. For suspended loads, a plain cylinder drifts on air loss—use an external rod lock or the SAIL/BSAI variants. The 160mm stroke is under the 300mm threshold, so side-load rod-bending risks are minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX160
- ✓ 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 SI100AX160 FAQ
Yes, the AirTAC SI100AX160 is discontinued and end-of-life. The direct replacement is the SAI100AX160. It features the same ISO 15552 mounting interface, 100mm bore, 160mm stroke, output force, G1/2 port, and accessories, fitting directly into existing fixtures.
This double-acting cylinder has a G1/2 air port. It delivers 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 force of 801 kgf at 1.0 MPa.
