This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X148, 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 SI32X148
The AirTAC SI32 Standard Air Cylinder SI32X148 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 148mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X148, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X148
The AirTAC SI32X148 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 148 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. The direct replacement is the SAI32X148, matching the exact interface, bore, stroke, force, and mounting.
This SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this specific SI SKU lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor.

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 SI32X148 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture with 402 N of push force at 0.5 MPa.
Package Diverting
Provides reliable actuation for a diverting arm on a 32 mm bore assembly line conveyor system.
Replacing the Airtac SI32 Standard Air Cylinder SI32X148 with the SAI32X148
To replace the SI32X148, order the SAI32X148. Verify the ISO 15552 mounting interface, 148 mm stroke, G1/8 port (PT/G/NPT thread), and mounting accessory. Because this SKU lacks the -S magnet, it cannot support position sensing; if detection is needed, specify an SAI32X148S. Sizing both ways: a 40 mm bore offers 628 N push at 0.5 MPa, while dropping to a 25 mm bore reduces force. For load holding on air loss, the cushion only decelerates; use an external pilot check valve or the SAIL/BSAI lock variant. With a 148 mm stroke, side-load is minimal, but ensure rod alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X148
- ✓ 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 SI32X148 FAQ
Yes, the AirTAC SI32X148 is discontinued. The direct replacement is the SAI32X148. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 148 mm stroke, output force, G1/8 port, and mounting interface.
The 32 mm bore uses a G1/8 port. Force 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.
