This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X830S, 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 SI32X830S
The AirTAC SI32 Standard Air Cylinder SI32X830S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 830mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X830S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X830S
The AirTAC SI32X830S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 830 mm stroke. Delivering 402 N push force at 0.5 MPa via a G1/8 port, it is replaced by the SAI32X830S. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke, force, and port size, fitting existing fixtures perfectly.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI32 Standard Air Cylinder SI32X830S Is Used
Light-Part Diversion
Ideal for pushing lightweight packages or routing small cardboard blanks on a 32 mm bore conveyor line with a long 830 mm reach.
Long-Reach Ejection
Handles the extended 830 mm stroke needed to eject small molded parts or empty containers from a press bed into a collection bin.
Sensor-Gated Sorting
Uses the -S magnet with CS1-B/DS1-B switches to confirm position when sorting small electronic components into packaging tubes.
Replacing the Airtac SI32 Standard Air Cylinder SI32X830S with the SAI32X830S
To replace the SI32X830S, order the SAI32X830S. Verify your ISO 15552 mounting accessories (LB, FA, TC, etc.), the G1/8 air port, and the M10x1.25 rod thread. Because this is an 830 mm stroke, add external guides to prevent rod bending and side-load damage. A plain cylinder drifts without live air; for load holding, use an external pilot check valve or the SAIL lock variant. If you need more force, the 40 mm bore offers 628 N push at 0.5 MPa; if less is acceptable, check smaller profiles.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X830S
- ✓ 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 SI32X830S FAQ
Yes, the SI32X830S is discontinued. The direct replacement is the SAI32X830S. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 830 mm stroke, output force, G1/8 port, and mounting interface.
This 32 mm bore double-acting cylinder uses a G1/8 port. It generates 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. Speed is 30-800 mm/s.
