This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X160, 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 SI100X160
The AirTAC Airtac SI100 Standard Cylinder SI100X160 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 SAI100X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X160
The AirTAC SI100X160 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 160 mm stroke, delivering 3927 N push force at 0.5 MPa. The direct replacement is the SAI100X160, which preserves the exact ISO 15552 mounting interface, G1/2 port, and output force. This SKU lacks a magnet (-S), meaning it cannot accept position sensors.
The SAI upgrade introduces a refined piston seal utilizing two Y-shaped one-way elements for extended life and lower start-up pressure. Buyers needing higher heat resistance can specify the Viton H seal option (0-150 C), while load-holding applications require the SAIL lock or BSAI clamp-lock variants, as a standard cylinder drifts without live air.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X160 Is Used
Heavy Press Clamping
Generates 3927 N of clamping thrust at 0.5 MPa to secure heavy metal workpieces during machining or welding operations.
Pallet Diverting
Provides robust actuation to push or divert loaded pallets across transfer lines, utilizing the 160 mm stroke effectively.
Replacing the Airtac SI100 Standard Cylinder SI100X160 with the SAI100X160
To replace the SI100X160, order the SAI100X160 and confirm the ISO 15552 mounting accessory (LB, FA, TC, etc.) and G1/2 port thread (PT, G, or NPT). Because this specific SKU has no magnet, it cannot support legacy CS1-B/DS1-B sensors; if switching is required, order an SAI variant with the magnet option and use current AirTAC switches. Sizing both ways: the 100 mm bore yields 3927 N push at 0.5 MPa (5497 N at 0.7 MPa), while the neighboring 80 mm bore provides 2513 N. Note that a plain double-acting cylinder does not hold load on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for vertical loads. For self-valve needs, explore the SAIF variant (available up to 100 mm).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X160
- ✓ 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 SI100X160 FAQ
Yes, the SI100X160 is discontinued. The direct replacement is the AirTAC SAI100X160. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 160 mm stroke, G1/2 port, and mounting interface.
This double-acting cylinder features a G1/2 port and delivers 3927 N push / 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.
