This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X410S, 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 SI32X410S
The AirTAC SI32 Standard Air Cylinder SI32X410S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 410mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X410S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X410S
The AirTAC SI32X410S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 410 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. The direct replacement is the SAI32X410S, matching the interface, bore, stroke, force, port and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It adds SAIL, SAIF and BSAI variants the SI lacked. The -S magnet works with legacy CS1-B/DS1-B sensors.

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 SI32X410S Is Used
Compact Part Ejection
Uses the 402 N push force at 0.5 MPa to eject small machined components from a fixture, leveraging the 410 mm stroke to clear the workspace entirely.
Light Package Sorting
Actuates a routing arm on a packaging line, safely handling loads near the 241 N safe working limit while benefiting from the 30-800 mm/s speed range.
Vertical Material Lift
Raises lightweight bins up to 20 kg through a 410 mm vertical path, requiring external linear guides to prevent rod bending on the long stroke.
Replacing the Airtac SI32 Standard Air Cylinder SI32X410S with the SAI32X410S
To replace the SI32X410S, order the SAI32X410S. Confirm the ISO 15552 mounting interface, 32 mm bore, 410 mm stroke, G1/8 port (PT/G/NPT thread), mounting accessory and the -S magnet. The SAI family adds SAIL (air-released lock), SAIF (built-in 4M valve) and BSAI (clamp-lock) variants. A plain cylinder drifts on air loss as the cushion only decelerates; use SAIL, BSAI or a pilot check valve to hold loads. For 410 mm strokes, prevent rod bending with external guides to manage side loads. Sizing both ways: the 40 mm bore gives 628 N push at 0.5 MPa, while the 32 mm bore provides 563 N at 0.7 MPa.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X410S
- ✓ 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 SI32X410S FAQ
Yes, the AirTAC SI32X410S is discontinued. The direct replacement is the SAI32X410S. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 410 mm stroke, output force, G1/8 port and mounting interface.
The 32 mm bore cylinder has a G1/8 air port. It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max force of 82 kgf at 1.0 MPa. The operating speed is 30-800 mm/s.
