This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X65, 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 SI32X65
The AirTAC SI32 Standard Air Cylinder SI32X65 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 SAI32X65, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X65
The AirTAC SI32X65 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 65mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X65. This direct upgrade shares the exact interface, bore, stroke, force and mounting.
The SAI features upgraded two Y-shaped one-way piston seals for low start-up pressure. Note this SKU lacks a magnet, so it cannot take a sensor. For load holding, explore SAIL or BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X65 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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32X65 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32X65 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using its 402N push force at 0.5 MPa.
Package Diverting
Actuates a short 65mm stroke diverter arm to route small boxes on a secondary packaging line at speed.
Clamp Actuation
Provides reliable clamping pressure for holding thin sheet metal or plastic parts during a light assembly process.
Replacing the Airtac SI32 Standard Air Cylinder SI32X65 with the SAI32X65
To replace the SI32X65, order the SAI32X65. Confirm the ISO 15552 mounting interface, 65mm stroke, G1/8 port (PT/G/NPT thread options), and your mounting accessory (LB, FA, TC, etc.). This non-magnet SKU cannot accept a CS1-B/DS1-B sensor. For sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while dropping to a 25mm stroke reduces cycle time. A plain cylinder drifts on air loss; for held loads use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant integrates a 4M valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X65
- ✓ 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 SI32X65 FAQ
Yes, the SI32X65 is discontinued. The direct replacement is the AirTAC SAI32X65. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 65mm stroke, output force, G1/8 port and mounting interface.
This double-acting cylinder has a G1/8 port and M10x1.25 rod thread. It generates 402N push and 345N pull at 0.5 MPa, 563N push at 0.7 MPa, 724N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa.
