This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X300N, 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 SI32X300N
The AirTAC SI32 Standard Air Cylinder SI32X300N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X300N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X300N
The AirTAC SI32X300N is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 300mm stroke. Delivering 402N push at 0.5MPa via a G1/8 port, it is directly replaced by the SAI32X300N. This direct upgrade shares identical ISO 15552 mounting dimensions, bore, and force, fitting existing fixtures perfectly.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this SKU lacks a magnet, it cannot take a sensor. The NBR seal suits -20 to +70C (Viton H extends this).

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X300N 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 SAI32X300N 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 SI32X300N Is Used
Small Part Ejection
Uses the 402N push force to reliably knock small machined components out of a fixture during automated machining cycles.
Package Diversion
Actuates a routing gate along a packaging line, where the 300mm stroke provides adequate travel to redirect lightweight cartons.
Compact Clamping
Secures thin workpieces in light assembly jigs where the compact 32mm bore footprint is required and vertical lift stays under 20kg.
Replacing the Airtac SI32 Standard Air Cylinder SI32X300N with the SAI32X300N
To replace the SI32X300N, order the SAI32X300N. Confirm the ISO 15552 interface, 32mm bore, 300mm stroke, G1/8 port (PT/G/NPT thread options), and mounting accessory. This non-magnet SKU cannot accept a sensor; if sensing is needed, order an SAI with the -S suffix for CS1-B/DS1-B compatibility. Sizing both ways: a 40mm bore offers 628N push at 0.5MPa, while a 32mm bore provides 402N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL/BSAI lock variant. For the 300mm stroke, use external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X300N
- ✓ 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 SI32X300N FAQ
Yes, the SI32X300N is discontinued. The direct replacement is the SAI32X300N. It is dimensionally interchangeable per ISO 15552, maintaining the same 32mm bore, 300mm stroke, force, and G1/8 port so it fits existing mounts.
The 32mm bore uses a G1/8 port. Force output is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. It operates at 30-800mm/s with a 27mm adjustable air cushion.
