This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X65SCA, 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 SI32X65SCA
The AirTAC SI32 Standard Air Cylinder SI32X65SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 65mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X65SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X65SCA
The AirTAC SI32X65SCA is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 65mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X65SCA, retaining the same CA clevis mounting, M10x1.25 rod thread, and output force.
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 lock variants the SI lacked. The -S magnet works with CS1-B/DS1-B sensors, while SAI uses current AirTAC switches.

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 SI32X65SCA Is Used
Small Part Clamping
Ideal for securing light electronics or plastic housings during machining, using the 402N push force to hold components firmly without deformation.
Package Diverting
Provides reliable actuation for low-profile conveyor sorting gates, where the 65mm stroke rapidly pushes lightweight cartons to secondary lanes.
Pallet Stops
Functions as a compact pneumatic stop in material handling lines, extending 65mm to halt small tote boxes before manual pickup or processing.
Replacing the Airtac SI32 Standard Air Cylinder SI32X65SCA with the SAI32X65SCA
To replace the SI32X65SCA, order the SAI32X65SCA. Verify the ISO 15552 interface, 65mm stroke, G1/8 port, and CA clevis mounting. The -S magnet enables CS1-B/DS1-B sensors. For sizing, the 402N push at 0.5MPa handles a 241N safe load; if undersized, step up to the 40mm bore (628N). A plain cylinder drifts without live air—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also offers the SAIF self-valve for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X65SCA
- ✓ 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 SI32X65SCA FAQ
Yes, the SI32X65SCA is discontinued. The direct replacement is the SAI32X65SCA. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 65mm stroke, G1/8 port, CA clevis mount, and 402N force.
It features a G1/8 port, M10x1.25 rod thread, and 27mm cushion. Forces are: 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a maximum theoretical force of 82kgf at 1.0MPa.
