This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X80STC, 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 SI32X80STC
The AirTAC SI32 Standard Air Cylinder SI32X80STC 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 SAI32X80STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X80STC
The AirTAC SI32X80STC 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 SAI32X80STC, a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and TC trunnion mount.
The SAI upgrade features a revised piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI accepts current AirTAC switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X80STC 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 SAI32X80STC 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 SI32X80STC Is Used
Package Diverting
Provides reliable 80 mm stroke actuation to sort small cartons on a conveyor line without occupying much space.
Clamp Actuation
Generates 402 N of push force at 0.5 MPa to secure delicate workpieces during secondary machining operations.
Replacing the Airtac SI32 Standard Air Cylinder SI32X80STC with the SAI32X80STC
To replace the SI32X80STC, order the SAI32X80STC. Confirm the ISO 15552 TC trunnion interface, 32 mm bore, 80 mm stroke, G1/8 port (PT/G/NPT thread options), and the -S magnet. Sizing both ways: stepping up to a 40 mm bore yields 628 N push at 0.5 MPa, while dropping to a smaller profile reduces force. Note that a plain cylinder drifts on air loss; the 27 mm adjustable cushion only decelerates the load. For holding loads, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X80STC
- ✓ 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 SI32X80STC FAQ
Yes, the SI32X80STC is discontinued. The direct replacement is the SAI32X80STC. It shares the same ISO 15552 mounting interface, 32 mm bore, 80 mm stroke, G1/8 port, and TC trunnion mount, fitting directly into existing fixtures.
This 32 mm bore cylinder features a G1/8 air port and provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum force of 82 kgf at 1.0 MPa.
