This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X63, 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 SI32X63
The AirTAC SI32 Standard Air Cylinder SI32X63 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 63mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X63, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X63
The AirTAC SI32X63 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 63mm stroke, delivering 402N push force at 0.5MPa through a G1/8 port. As a legacy unit, it must be replaced by the current SAI32X63 direct equivalent.
The SAI32X63 retains the exact ISO 15552 mounting interface, bore, stroke, output force, port size and accessories. It features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. For sensing, this specific non-magnet SKU cannot accept a switch; legacy -S versions used CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X63 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 SAI32X63 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 SI32X63 Is Used
Small Part Ejection
Ideal for pushing lightweight finished parts out of a machining center using the 402N push force at 0.5 MPa.
Compact Clamping
Secures small electronic housings or thin material blanks during light assembly or drilling tasks.
Package Diverting
Acts as a short-stroke diverter arm on a packaging line, moving small cartons without overwhelming the load.
Replacing the Airtac SI32 Standard Air Cylinder SI32X63 with the SAI32X63
To replace the SI32X63, order the SAI32X63 and verify your ISO 15552 mounting fixture (LB, FA, TC, etc.), 63mm stroke, and G1/8 port. Because this SKU lacks the -S magnet, it cannot support position sensing; if sensing is required, order the SAI32X63S. The 32mm bore yields 402N push at 0.5MPa; if more force is needed, the 40mm bore provides 628N. For load holding, note that a standard cylinder drifts on air loss—the cushion only decelerates—so add an external pilot check valve or use the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X63
- ✓ 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 SI32X63 FAQ
Yes, the SI32X63 is discontinued. The direct replacement is the SAI32X63. It is dimensionally interchangeable per the ISO 15552 mounting interface, matching the 32mm bore, 63mm stroke, 402N force, G1/8 port and mounting accessories.
The G1/8 port bore delivers a push force of 402N and a pull force of 345N at 0.5MPa. At 0.7MPa the push force is 563N, and at 0.9MPa it is 724N. The theoretical maximum force is 82kgf at 1.0MPa.
