This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X232, 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 SI32X232
The AirTAC SI32 Standard Air Cylinder SI32X232 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 232mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X232, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X232
The AirTAC SI32X232 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 232mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X232, sharing the same interface, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. This SKU lacks a magnet (-S), so it cannot take CS1-B/DS1-B sensors. Note that 232mm is a nonstandard stroke.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32X232 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32X232 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture on an assembly line.
Package Diverting
Actuates a routing gate at 30-800mm/s to sort small boxes on a conveyor, taking advantage of the compact 32mm profile barrel.
Clamp Actuation
Secures thin workpieces during light machining, providing a 345N pull force while fitting into tight tooling spaces.
Replacing the Airtac SI32 Standard Air Cylinder SI32X232 with the SAI32X232
To replace this SI with the SAI32X232, confirm the ISO 15552 mounting interface, 32mm bore, 232mm nonstandard stroke, G1/8 port, and mounting accessory. Since there is no -S magnet, this cylinder cannot accept position sensors. For sizing, the 40mm bore offers higher force (628N push at 0.5MPa), while the 32mm bore provides 402N. As 232mm exceeds standard lengths, ensure side-load alignment to prevent rod bending. A plain cylinder does not hold load without air; for load holding, use an external rod lock or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X232
- ✓ 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 SI32X232 FAQ
Yes, the SI32X232 is discontinued. The direct replacement is the SAI32X232, which maintains the same ISO 15552 mounting interface, 32mm bore, 232mm stroke, force, and G1/8 port.
This double-acting cylinder has a G1/8 port and delivers 402N push / 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. The 232mm stroke is nonstandard.
