This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X90SH, 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 SI32X90SH
The AirTAC SI32 Standard Air Cylinder SI32X90SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 90mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X90SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X90SH
The AirTAC SI32X90SH is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 90 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced this legacy unit with the SAI32X90SH, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting accessories.
The SAI upgrade features a modernized piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. The original SI utilized a CS1-B/DS1-B sensor set, while the new SAI family uses current AirTAC switches. For high-temperature environments, the Viton H seal option expands the operating range to 0-150 C.

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 SI32X90SH Is Used
Small Part Ejection
Ideal for pushing lightweight finished components out of a machining center using the 402 N push force at 0.5 MPa.
Package Diverting
Deploys a 90 mm stroke to deflect small cartons on a packaging line, safely handling loads around the 20 kg vertical lift threshold.
Clamp Actuation
Secures thin workpieces in assembly fixtures where a compact 32 mm bore and G1/8 port integration are required.
Replacing the Airtac SI32 Standard Air Cylinder SI32X90SH with the SAI32X90SH
To replace the SI32X90SH, order the SAI32X90SH and confirm the ISO 15552 mounting interface, 32 mm bore, 90 mm stroke, G1/8 port, and the -S magnet for position sensing. If sizing up, the adjacent 40 mm bore yields 628 N push at 0.5 MPa; if sizing down, options are unavailable as 32 mm is the smallest. Remember that a plain cylinder does not hold load on air loss—the cushion only decelerates. For secure holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The SAIF variant offers a built-in valve if needed. The standard 30-800 mm/s speed range applies.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X90SH
- ✓ 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 SI32X90SH FAQ
Yes, the SI32X90SH is discontinued. The direct replacement is the AirTAC SAI32X90SH. It shares the identical ISO 15552 mounting interface, 32 mm bore, 90 mm stroke, output force, G1/8 port, and mounting accessories, fitting directly into existing fixtures.
The 32 mm bore features a G1/8 air port and M10x1.25 rod thread. It generates 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 maximum force of 82 kgf at 1.0 MPa.
