This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X75, 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 SI32X75
The AirTAC SI32 Standard Air Cylinder SI32X75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X75
The AirTAC SI32X75 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 75 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. The direct replacement is the SAI32X75, matching the exact ISO 15552 mounting interface, bore, stroke, output force, port size and accessories.
Upgrading to the SAI32X75 brings a refined piston seal featuring two Y-shaped one-way elements for extended life and low start-up pressure. This no-magnet SKU cannot accept a sensor, and the SAI family expands capabilities with SAIL, SAIF and BSAI lock or valve variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X75 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 | — |

Where the Airtac SI32 Standard Air Cylinder SI32X75 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture with a reliable 402 N push force at 0.5 MPa.
Compact Clamping
Provides precise 75 mm actuation to clamp delicate electronics housings without overwhelming the assembly.
Package Diverting
Handles short-stroke diverting tasks on packaging lines where a compact 32 mm bore and G1/8 port fit tight spaces.
Replacing the Airtac SI32 Standard Air Cylinder SI32X75 with the SAI32X75
To replace the SI32X75, order the SAI32X75 and confirm the ISO 15552 mounting interface, 75 mm stroke, G1/8 port (PT/G/NPT thread options) and your mounting accessory (LB, FA, TC, etc.). Because this specific SKU lacks the -S magnet suffix, it cannot accommodate a position sensor; if sensing is required, select an SAI32X75S and use current AirTAC switches. A plain cylinder does not hold load on air loss—the cushion only decelerates—so for suspended loads use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X75
- ✓ 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 SI32X75 FAQ
Yes, the AirTAC SI32X75 is discontinued. The direct replacement is the SAI32X75. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 75 mm stroke, output force, G1/8 port and mounting interface to fit existing fixtures directly.
This double-acting cylinder uses a G1/8 air port. The thrust ratings are 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 of 82 kgf at 1.0 MPa.
