This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X460S, 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 SI32X460S
The AirTAC SI32 Standard Air Cylinder SI32X460S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 460mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X460S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X460S
The AirTAC SI32X460S is a discontinued double-acting ISO 15552 profile cylinder. Delivering 402 N push at 0.5 MPa, it features a 32 mm bore, 460 mm stroke, G1/8 port, and a piston magnet for CS1-B/DS1-B switches. The direct replacement is the SAI32X460S, matching the interface, force, and mounting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The family adds SAIL, SAIF, and BSAI variants. Rod options include SUS420J2 or SUS304.

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 SI32X460S Is Used
Small Parts Ejection
Uses the 402 N push force to eject small machined components from a fixture, fitting neatly into compact automated machinery.
Package Diverting
The 460 mm stroke extends across a narrow belt to divert lightweight packages, with the magnet confirming position for the controller.
Replacing the Airtac SI32 Standard Air Cylinder SI32X460S with the SAI32X460S
To replace the SI32X460S, order the SAI32X460S. Confirm the ISO 15552 mounting interface, 32 mm bore, 460 mm stroke, G1/8 port (PT/G/NPT), and mounting accessory. The -S magnet enables current AirTAC switches. At 0.5 MPa it yields 402 N push and 345 N pull; neighboring bores (40 mm) offer 628 N push. For the 460 mm stroke, use external guides to prevent rod bending. The cushion only decelerates; for load holding use an external rod lock, pilot check valve, or SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X460S
- ✓ 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 SI32X460S FAQ
Yes, the SI32X460S is discontinued. The direct replacement is the SAI32X460S. It is dimensionally interchangeable per ISO 15552, keeping the same 32 mm bore, 460 mm stroke, output force, G1/8 port, and mounting interface.
The G1/8 port bore 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 max force of 82 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 27 mm adjustable cushion.
