This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X25TC, 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 SI160X25TC
The AirTAC SI160 Standard Cylinder SI160X25TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 25mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X25TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X25TC
The AirTAC SI160X25TC is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 25mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X25TC, matching the interface, force, and TC trunnion mount exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For load holding, note the air cushion only decelerates; use a pilot check valve or SAIL lock variant. This no-magnet SKU cannot take a sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160X25TC 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 SAI160X25TC 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 SI160X25TC Is Used
Heavy Pressing
Generates 14074 N at 0.7 MPa for seating large components and heavy-duty pressing tasks.
Clamp Actuation
Provides 18095 N at 0.9 MPa for securing massive fixtures during machining operations.
Replacing the Airtac SI160 Standard Cylinder SI160X25TC with the SAI160X25TC
To replace the SI160X25TC, order the SAI160X25TC. Confirm the ISO 15552 TC trunnion interface, 160mm bore, 25mm stroke, and G3/4 port (PT/G/NPT thread options). This SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors; order a magnet-equipped SAI if position sensing is needed. At 0.5 MPa it yields 10053 N push (9425 N pull); dropping to a 125mm bore gives 6136 N. For holding loads without live air, the cushion only decelerates—specify an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X25TC
- ✓ 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 SI160X25TC FAQ
Yes, the SI160X25TC is discontinued. The direct replacement is the SAI160X25TC. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 25mm stroke, G3/4 port, and TC mounting interface.
This double-acting cylinder features a G3/4 port and a 40mm rod. It outputs 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa.
