This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X580S, 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 SI32X580S
The AirTAC SI32 Standard Air Cylinder SI32X580S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 580mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X580S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X580S
The AirTAC SI32X580S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 580 mm stroke. Delivering 402 N push force at 0.5 MPa, it is replaced directly by the SAI32X580S. This direct successor retains the exact G1/8 port, M10x1.25 thread, and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family adds SAIL, SAIF, and BSAI variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

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 SAI32X580S 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 SI32X580S Is Used
Component Ejection
Pushes light machined parts out of an assembly fixture over a 580 mm gap, using the 402 N push force at 0.5 MPa to clear the workspace reliably.
Package Diverting
Actuates a sorting arm across a conveyor belt, where the 32 mm bore provides sufficient speed and the 580 mm stroke reaches the far lane.
Replacing the Airtac SI32 Standard Air Cylinder SI32X580S with the SAI32X580S
To replace the SI32X580S, order the SAI32X580S. Verify the ISO 15552 mounting interface, 32 mm bore, 580 mm stroke, G1/8 port (PT/G/NPT), and mounting accessory. The -S magnet enables CS1-B/DS1-B sensors (SAI uses current AirTAC switches). Sizing both ways: step down to a 20 mm bore for lighter loads, or up to a 40 mm bore (628 N push @0.5 MPa) for more force. For the 580 mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X580S
- ✓ 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 SI32X580S FAQ
Yes, the AirTAC SI32X580S is discontinued. The direct replacement is the SAI32X580S. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 580 mm stroke, output force, G1/8 port, and mounting interface.
The 32 mm bore features a G1/8 air port and M10x1.25 rod thread. Force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
