This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX160S, 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 SI32 Standard Air Cylinder SI32AX160S
The AirTAC SI32 Standard Air Cylinder SI32AX160S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 160mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX160S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX160S
The AirTAC SI32AX160S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 160mm stroke. Providing 402N push force at 0.5MPa, it features a SUS420J2 stainless piston rod and a G1/8 port. The direct replacement is the SAI32AX160S, matching the bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked. The built-in magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI32 Standard Air Cylinder SI32AX160S Is Used
Light Part Ejection
Provides reliable push force to eject lightweight plastic or aluminium parts from molding fixtures without damaging surfaces.
Package Diverting
Used in material handling lines to push small cartons or totes at speeds up to 800 mm/s using the integrated magnet for position confirmation.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX160S with the SAI32AX160S
To replace the SI32AX160S, order the SAI32AX160S keeping the identical 32mm bore, 160mm stroke, G1/8 port, M10x1.25 thread, SUS420J2 rod and ISO 15552 mounting. If downsizing, neighbouring bores offer less force; if upsizing to 40mm, you gain 628N push at 0.5MPa. A plain cylinder drifts on air loss as the cushion only decelerates, so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. For this 160mm stroke, ensure guide alignment to prevent rod bending side-loads. The -S magnet supports CS1-B/DS1-B switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX160S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI32 Standard Air Cylinder SI32AX160S FAQ
Yes, the SI32AX160S is discontinued. The direct replacement is the SAI32AX160S. It is dimensionally interchangeable per ISO 15552, offering the same 32mm bore, 160mm stroke, 402N force, G1/8 port and mounting interface, but features an upgraded piston seal for longer life.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Operating speed is 30-800 mm/s, with a 27mm adjustable air cushion at each end and a G1/8 air port.
