This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX90S, 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 SI160BX90S
The AirTAC SI160 Standard Cylinder SI160BX90S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX90S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX90S
The AirTAC SI160BX90S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 90 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160BX90S, matching the bore, stroke, force, port, and ISO 15552 mounting interface exactly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SI unit includes a SUS304 stainless rod (-B) and a piston magnet (-S) for CS1-B/DS1-B sensors. For load holding, note that a plain cylinder drifts without air; use an external rod lock or SAIL/BSAI variant.

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 SAI160BX90S 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 SI160BX90S Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring 10053 N push force at 0.5 MPa, utilizing the 90 mm stroke for rapid high-tonnage actuation.
Pallet Handling Systems
Indexes heavy loaded pallets on conveyors where the SUS304 stainless rod provides corrosion resistance in damp or washdown logistics environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX90S with the SAI160BX90S
To replace the SI160BX90S, order the SAI160BX90S. Verify the ISO 15552 mounting interface, 90 mm stroke, G3/4 port, and the -S magnet for current AirTAC switches. This -B variant uses a SUS304 stainless rod for corrosion resistance. If sizing down, a 125 mm bore yields 6136 N push @0.5 MPa; sizing up to 200 mm provides 15708 N. For load holding on air loss, the standard cushion only decelerates; add a pilot check valve or specify the SAIL/BSAI lock variant. With a 90 mm stroke, side-load risks are minimal, but ensure guide alignment to protect the M36x2 rod thread.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX90S
- ✓ 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 SI160BX90S FAQ
Yes, the AirTAC SI160BX90S is discontinued. The direct replacement is the SAI160BX90S. It shares the exact same ISO 15552 mounting interface, 160 mm bore, 90 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
It features a G3/4 port and delivers a push force of 10053 N and pull of 9425 N at 0.5 MPa. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical max force is 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
