This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X36, 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 SI32X36
The AirTAC SI32 Standard Air Cylinder SI32X36 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 36mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X36, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X36
The AirTAC SI32X36 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 36 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced it with the SAI32X36, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force and port size.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This SKU lacks a magnet (-S), so it cannot accept a CS1-B/DS1-B sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X36 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 SAI32X36 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 SI32X36 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably kick small molded parts out of an aluminum fixture.
Light Clamping
Secures delicate electronic housings during ultrasonic welding without crushing the 32 mm bore footprint.
Gate Diversion
Powers a short 36 mm stroke diverter arm to route lightweight product packaging between conveyor lanes.
Replacing the Airtac SI32 Standard Air Cylinder SI32X36 with the SAI32X36
To replace the SI32X36, order the SAI32X36 and verify the ISO 15552 mounting interface, G1/8 port, and 36 mm stroke. Because this SKU has no magnet, you cannot mount position sensors; if sensing is needed, order an SAI32X36S instead. For higher force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external pilot check valve or the SAIL lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X36
- ✓ 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 SI32X36 FAQ
Yes, the SI32X36 is discontinued. The direct replacement is the AirTAC SAI32X36. It shares the identical ISO 15552 mounting interface, 32 mm bore, 36 mm stroke, output force, G1/8 port and mounting accessories, fitting directly into existing fixtures.
The 32 mm bore uses a G1/8 port. At 0.5 MPa it provides 402 N push and 345 N pull. At 0.7 MPa push is 563 N, at 0.9 MPa push is 724 N, and the theoretical maximum force is 82 kgf at 1.0 MPa.
