This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X80, 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 SI32X80
The AirTAC SI32 Standard Air Cylinder SI32X80 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X80
The AirTAC SI32X80 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced this legacy unit with the SAI32X80, a direct sharing the exact bore, stroke, output force, and mounting interface.
The SAI upgrade features a refined piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life. For load holding, note that a standard cylinder drifts without live air; the cushion only decelerates. Use an external rod lock or SAIL variant to hold.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X80 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI32X80 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 SI32X80 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded plastic components out of a machining fixture.
Package Diverting
Short 80 mm stroke actuates a diverter gate on a packaging line, handling the 20 kg vertical lift capacity safely.
Clamp Actuation
Secures small electronic housings during an assembly process, taking advantage of the compact 32 mm ISO 15552 profile.
Replacing the Airtac SI32 Standard Air Cylinder SI32X80 with the SAI32X80
To replace the SI32X80, order the SAI32X80 and confirm the ISO 15552 mounting interface, 32 mm bore, 80 mm stroke, G1/8 port, and accessory type. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CS1-B or DS1-B sensor; order a magnet-equipped SAI if position sensing is required. If sizing up, the 40 mm bore yields 628 N push at 0.5 MPa; sizing down is not available below 32 mm. Since this 80 mm stroke is under 300 mm, rod-bending side loads are minimal, but always guide external loads. For applications needing dead-end holding, select the SAIL air-released lock or BSAI clamp-lock variant, as standard air cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X80
- ✓ 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 SI32X80 FAQ
Yes, the SI32X80 is discontinued. The direct replacement is the SAI32X80. It shares the identical ISO 15552 mounting interface, 32 mm bore, 80 mm stroke, output force, and G1/8 port, fitting seamlessly into existing fixtures.
This double-acting cylinder uses a G1/8 air port. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and 724 N push at 0.9 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
