This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX180S, 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 SI32AX180S
The AirTAC SI32 Standard Air Cylinder SI32AX180S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 180mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX180S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX180S
The AirTAC SI32AX180S is a discontinued double-acting ISO 15552 profile cylinder featuring a 32mm bore, 180mm stroke, and a magnetic piston for position sensing. Delivering 402N push force at 0.5MPa, it utilizes a G1/8 port and an M10x1.25 rod thread. The direct replacement is the SAI32AX180S, matching the original bore, stroke, force, and ISO 15552 mounting interface for seamless fixture integration.
The SAI32AX180S upgrades the piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The original SI32AX180S features the SUS420J2 stainless steel rod option and CS1-B/DS1-B legacy sensors.

Where the Airtac SI32 Standard Air Cylinder SI32AX180S Is Used
Small Part Ejection
Ideal for pushing lightweight finished components out of machining centers using a safe 241N working load.
Package Diverting
Actuates routing gates on packaging lines where a 20kg vertical lift capability handles product weight reliably.
Clamp Actuation
Provides precise 402N clamping force for holding small aluminum or plastic workpieces during light assembly.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX180S with the SAI32AX180S
To replace the SI32AX180S, order the SAI32AX180S, confirming the ISO 15552 interface, 32mm bore, 180mm stroke, G1/8 port, and mounting accessory. The -S magnet allows for current AirTAC switches. If sizing up, the 40mm bore yields 628N push at 0.5MPa; if downsizing, the 20mm bore offers less force. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 180mm stroke, side-load is minimal, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX180S
- ✓ 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 SI32AX180S FAQ
