This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX220S, 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 SI32AX220S
The AirTAC SI32 Standard Air Cylinder SI32AX220S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 220mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX220S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX220S
The AirTAC SI32AX220S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore, 220mm stroke, and an SUS420J2 stainless steel rod. Generating 402N push force at 0.5MPa via a G1/8 port, it is directly replaced by the SAI32AX220S. This direct upgrade shares identical ISO 15552 mounting dimensions, stroke, and force, but adds an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The magnet allows legacy CS1-B/DS1-B sensors.
The SAI family introduces variants the SI lacked, like the SAIL air-released lock and BSAI clamp-lock for load holding, since a plain cylinder drifts without live air. Viton H seals expand the temperature range to 0-150C.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SI32 Standard Air Cylinder SI32AX220S Is Used
Package Diverting
Provides reliable diverting force on conveyor lines; the 402N thrust at 0.5MPa smoothly actuates routing gates without overwhelming the mechanical stops.
Light Lift Gates
Suitable for actuating lightweight access doors or flaps up to 20kg, though an external pilot check valve or SAIL lock variant is required if gravity causes drift.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX220S with the SAI32AX220S
To replace the SI32AX220S, order the SAI32AX220S. Verify the ISO 15552 mounting interface, 32mm bore, 220mm stroke, G1/8 port, and the -S magnet for current AirTAC switches. The SUS420J2 rod (-A) provides corrosion resistance versus standard carbon steel. If you need more force, the neighboring 40mm bore yields 628N push at 0.5MPa; if less is acceptable, consider smaller profiles. Because this is a 220mm stroke, ensure adequate guide support to prevent rod bending under side loads. Remember that standard cylinders do not hold load without live air; for vertical or held loads, use the SAIL or BSAI lock variants, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX220S
- ✓ 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 SI32AX220S FAQ
Yes, the SI32AX220S is discontinued. The direct replacement is the SAI32AX220S. It features the same ISO 15552 mounting interface, 32mm bore, 220mm stroke, output force, G1/8 port, and SUS420J2 rod, fitting existing fixtures perfectly while upgrading the piston seal.
The 32mm bore uses a G1/8 port and features a 12mm rod with an M10x1.25 thread. At 0.5MPa it provides 402N push and 345N pull force. At 0.7MPa push is 563N, and 724N at 0.9MPa. The theoretical maximum force is 82kgf at 1.0MPa.
