This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X75, 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 SI160 Standard Cylinder SI160X75
The AirTAC Airtac SI160 Standard Cylinder SI160X75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X75
The AirTAC SI160X75 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 75 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X75, retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
Because this SKU lacks the -S magnet, it cannot accept position sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure, and adds SAIL or BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160X75 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X75 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X75 Is Used
Heavy Press Forming
Generates 14074 N at 0.7 MPa to seat bearings or stamp thick plate in automated fabrication cells.
Injection Mold Clamping
Holds heavy mold halves shut using the 18095 N available at 0.9 MPa operating pressure.
Replacing the Airtac SI160 Standard Cylinder SI160X75 with the SAI160X75
To replace the SI160X75, order the SAI160X75 ensuring your ISO 15552 mounting accessories, G3/4 port, and M36x2 rod thread match. This non-magnetic SKU cannot take legacy CS1-B/DS1-B sensors. If you need more force than the 10053 N at 0.5 MPa, stepping up to the 200 mm bore provides 15708 N; conversely the 125 mm bore offers 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding specify an external pilot check valve or the SAIL lock variant. The 75 mm stroke keeps the rod compact, minimizing side-load bending risks.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X75
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X75 FAQ
Yes, the SI160X75 is discontinued. The direct replacement is the SAI160X75, which matches the ISO 15552 mounting interface, 160 mm bore, 75 mm stroke, output force, and G3/4 port size for a seamless fixture swap.
It features a G3/4 port and delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and 18095 N push at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
