This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X25FA, 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 SI32X25FA
The AirTAC SI32 Standard Air Cylinder SI32X25FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X25FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X25FA
The AirTAC SI32X25FA is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 25 mm stroke. It delivered 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced this EOL unit with the SAI32X25FA, a direct sharing the exact FA flange mounting, stroke and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. For sensing, this specific no-S SKU lacks a magnet and cannot accept a switch. The family also adds SAIL, SAIF and BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X25FA 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 SAI32X25FA 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 SI32X25FA Is Used
Small Part Ejection
Provides a fast 30-800 mm/s ejection thrust of 402 N at 0.5 MPa to push small components out of automated dies.
Gate Diverting
Actuates light conveyor sorting flaps where a compact 32 mm bore and FA flange mount fit tight machinery spaces.
Replacing the Airtac SI32 Standard Air Cylinder SI32X25FA with the SAI32X25FA
To replace the SI32X25FA, order the SAI32X25FA. Confirm the ISO 15552 FA flange interface, 32 mm bore, 25 mm stroke, G1/8 port and thread option (PT/G/NPT). This non-magnetic SKU cannot hold a load without live air; the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. To size both ways: a 40 mm bore yields 628 N push at 0.5 MPa, while dropping to 0.3 MPa yields 241 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X25FA
- ✓ 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 SI32X25FA FAQ
Yes, the SI32X25FA is discontinued. The direct replacement is the SAI32X25FA. It shares the identical ISO 15552 FA flange mounting interface, 32 mm bore, 25 mm stroke, G1/8 port and output force, fitting existing fixtures perfectly.
It features a G1/8 port and M10x1.25 rod thread. Force ratings are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Speed is 30-800 mm/s.
