This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X290, 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 SI32X290
The AirTAC SI32 Standard Air Cylinder SI32X290 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 290mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X290, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X290
The AirTAC SI32X290 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 290mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X290, matching the exact interface, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. Note this SKU lacks a magnet (-S) and cannot accept a CS1-B/DS1-B sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X290 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 SAI32X290 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 SI32X290 Is Used
Small Part Ejection
Pushes lightweight machined components out of a fixture with a safe 241N working load over the 290mm travel.
Package Diverting
Actuates a routing gate on a packaging line where 402N push force at 0.5MPa is sufficient for light cartons.
Bin Push-Off
Cycles 290mm to clear small totes from a pick station, operating reliably at speeds between 30-800 mm/s.
Replacing the Airtac SI32 Standard Air Cylinder SI32X290 with the SAI32X290
To replace this SI32X290, order the SAI32X290 keeping the identical 32mm bore, 290mm stroke, G1/8 port, and ISO 15552 mounting. Because this stroke is 290mm, ensure your guide handles side-load and rod-bending forces. For sizing, the neighboring 40mm bore yields 628N push at 0.5MPa if more force is needed. This plain cylinder does not hold load on air loss; use an external pilot check valve or the SAIL/BSAI lock variants for secure holding. This non-magnetic SKU cannot take a sensor.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X290
- ✓ 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 SI32X290 FAQ
Yes, the SI32X290 is discontinued. The direct replacement is the SAI32X290. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 290mm stroke, output force, G1/8 port, and mounting fixtures.
This double-acting cylinder uses a G1/8 port. The thrust figures are: 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa.
