This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X700STC, 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 SI160X700STC
The AirTAC SI160 Standard Cylinder SI160X700STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X700STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X700STC
The AirTAC SI160X700STC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 700 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X700STC, matching the ISO 15552 mounting interface, bore, stroke, force, and TC trunnion mount.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family adds SAIL, SAIF, and BSAI lock variants the SI lacked. This -S SKU uses CS1-B/DS1-B sensors; no-S SKUs cannot take sensors.

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 SAI160X700STC 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 SI160X700STC Is Used
Heavy Machinery Forming
Drives large press platens and forming dies requiring up to 14074 N thrust at 0.7 MPa within ISO 15552 fixtures.
Palletized Load Shifting
Shifts heavy unit loads along a 700 mm travel path, relying on external guides to prevent rod side-load bending.
Vertical Material Lowering
Lowers 500 kg assemblies safely; needs a SAIL lock or external pilot check valve to hold the load without live air.
Replacing the Airtac SI160 Standard Cylinder SI160X700STC with the SAI160X700STC
To replace the SI160X700STC, order the SAI160X700STC. Confirm the ISO 15552 TC trunnion interface, 160 mm bore, 700 mm stroke, G3/4 port, and -S magnet for CS1-B/DS1-B switches. Sizing both ways: neighbor bores are 125 mm (6136 N [email protected]) and 200 mm (15708 N). At 0.7 MPa this 160 mm bore pushes 14074 N. A plain cylinder drifts on air loss—the cushion only decelerates. For load holding use the SAIL or BSAI lock variant, or an external pilot check valve. With a 700 mm stroke, use an external guide to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X700STC
- ✓ 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 SI160X700STC FAQ
Yes, the AirTAC SI160X700STC is discontinued. The direct replacement is the SAI160X700STC. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 700 mm stroke, G3/4 port, TC trunnion mount, and output force.
This double-acting cylinder has a G3/4 port. Force ratings are: 10053 N push and 9425 N pull at 0.5 MPa; 14074 N push at 0.7 MPa; 18095 N push at 0.9 MPa; and a theoretical max of 2050 kgf at 1.0 MPa.
