This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX100S, 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 SI160AX100S
The AirTAC Airtac SI160 Standard Cylinder SI160AX100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX100S
The AirTAC SI160AX100S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 100mm stroke. It delivers 10053N push force at 0.5MPa through a G3/4 port. The direct replacement is the SAI160AX100S, matching the interface, stroke, force, and mounting. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
This unit has a SUS420J2 stainless piston rod (-A) and a magnet (-S) for CS1-B/DS1-B switches. Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants the SI lacked.

Where the Airtac SI160 Standard Cylinder SI160AX100S Is Used
Heavy Press Operations
Drives substantial forming and stamping presses requiring up to 10053N of thrust at 0.5MPa, utilizing the 100mm stroke for rapid high-force cycles.
Pallet Dispensing
Actuates large automated pallet dispensers and heavy material lifts where the SUS420J2 stainless rod resists moisture and the 512kg vertical lift capacity excels.
Large Mold Handling
Shifts heavy industrial molds and tooling along production lines, benefiting from the robust 160mm ISO 15552 profile barrel and adjustable 50mm cushions.
Replacing the Airtac SI160 Standard Cylinder SI160AX100S with the SAI160AX100S
To replace this SI160AX100S, order the SAI160AX100S. Confirm the ISO 15552 mounting interface, 160mm bore, 100mm stroke, G3/4 port (PT/G/NPT thread), and mounting accessory. The -S magnet enables current AirTAC switches (replacing legacy CS1-B/DS1-B), and the -A rod is SUS420J2 stainless. Sizing both ways: this bore yields 10053N push at 0.5MPa; a neighbouring 200mm bore offers 15708N, while a 125mm bore provides 6136N. A plain cylinder does not hold load without live air, so for drop-out prevention consider the SAIL lock, BSAI clamp-lock, or an external pilot check valve. Since the stroke is 100mm, side-load rod-bending risks are low, but standard guide rules still apply.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX100S
- ✓ 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 SI160AX100S FAQ
Yes, the SI160AX100S is discontinued. The direct replacement is the SAI160AX100S. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 100mm stroke, 10053N force, G3/4 port, and mounting fixtures.
This double-acting cylinder uses a G3/4 port. It delivers 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max of 2050 kgf at 1.0MPa.
