This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX80S, 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 SI160BX80S
The AirTAC SI160 Standard Cylinder SI160BX80S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX80S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX80S
The AirTAC SI160BX80S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 80 mm stroke. It delivers 10053 N push force at 0.5 MPa and uses a G3/4 air port. The direct replacement is the SAI160BX80S, which maintains the exact same ISO 15552 mounting interface, bore, stroke, output force, and porting for a seamless fixture swap.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. This specific SKU includes the SUS304 stainless steel piston rod and a piston magnet for legacy CS1-B/DS1-B 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 SAI160BX80S 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 SI160BX80S Is Used
Heavy-Duty Pressing
Drives large stamping and forming dies requiring up to 14074 N of thrust at 0.7 MPa within compact 80 mm travel.
Pallet Positioning
Indexes heavy loaded pallets on packaging lines, utilizing the robust 40 mm SUS304 stainless piston rod for rigidity.
Industrial Clamp Systems
Secures large fabricated components during machining, relying on 9425 N pull force at 0.5 MPa for reliable holding.
Replacing the Airtac SI160 Standard Cylinder SI160BX80S with the SAI160BX80S
To replace the discontinued SI160BX80S, order the SAI160BX80S and confirm the ISO 15552 mounting interface, 160 mm bore, 80 mm stroke, G3/4 port, and your specific mounting accessory. This unit has the -S magnet and -B SUS304 stainless rod. If downsizing, a 125 mm bore yields 6136 N at 0.5 MPa; if upsizing, a 200 mm bore yields 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end. For load holding, specify the SAIL lock or BSAI clamp-lock variant, or use an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX80S
- ✓ 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 SI160BX80S FAQ
Yes, the AirTAC SI160BX80S is discontinued. The direct replacement is the SAI160BX80S. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 80 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder uses a G3/4 port. It generates 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 maximum of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
