This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X220S, 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 SI32X220S
The AirTAC SI32 Standard Air Cylinder SI32X220S 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 SAI32X220S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X220S
The AirTAC SI32X220S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 220mm stroke. Delivering 402N push force at 0.5MPa, it features a G1/8 port and M10x1.25 rod thread. The direct replacement is the SAI32X220S, matching the exact ISO 15552 mounting interface, bore, stroke, output force, and porting for seamless fixture integration.
The SAI upgrade introduces an advanced 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 absent in the legacy line. Your -S magnet equips this cylinder for CS1-B/DS1-B position sensing.

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 SI32X220S Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of CNC fixtures using its 402N thrust and 220mm travel.
Gate Diverting
Actuates sorting flaps on packaging lines, benefiting from the adjustable 27mm air cushions at both ends.
Replacing the Airtac SI32 Standard Air Cylinder SI32X220S with the SAI32X220S
To replace the SI32X220S, order the SAI32X220S keeping the exact 32mm bore, 220mm stroke, G1/8 port, and ISO 15552 mounting. Confirm your thread standard (PT/G/NPT) and mounting accessory (LB, FA, TC, etc.). The -S magnet allows legacy CS1-B/DS1-B sensors, though the SAI accepts current AirTAC switches. Sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while dropping to 0.3MPa yields 241N. Note that a plain cylinder drifts without live air; the cushion only decelerates. For load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve. At 220mm stroke, side-load is minimal, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X220S
- ✓ 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 SI32X220S FAQ
Yes, the SI32X220S is discontinued. The direct replacement is the SAI32X220S. It shares the identical ISO 15552 mounting interface, 32mm bore, 220mm stroke, output force, and G1/8 port, fitting existing fixtures perfectly.
This double-acting cylinder has a 32mm bore, 12mm rod, M10x1.25 thread, and operates at 30-800 mm/s. Force ratings are 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N at 0.9MPa, and a maximum theoretical force of 82kgf at 1.0MPa.
