This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X240, 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 SI32X240
The AirTAC SI32 Standard Air Cylinder SI32X240 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 240mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X240, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X240
The AirTAC SI32X240 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 240mm stroke. Delivering 402N push force at 0.5MPa, it is replaced by the SAI32X240. This direct upgrade matches the exact G1/8 port, M10x1.25 thread, and mounting interface.
The SAI features an upgraded two Y-shaped one-way piston seal for low start-up pressure. This SKU lacks a magnet, so it cannot take a sensor. For high heat, Viton H seals raise limits to 150C.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X240 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 SAI32X240 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 SI32X240 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture.
Package Diverting
Actuates a routing gate along a packaging line, where the 240mm stroke provides ample travel distance.
Replacing the Airtac SI32 Standard Air Cylinder SI32X240 with the SAI32X240
To replace this SI32X240, order the SAI32X240 ensuring the ISO 15552 interface, 32mm bore, 240mm stroke, G1/8 port, and mounting accessory match. Because this non-magnet SKU cannot hold a sensor, order an -S model if position detection is needed. At 0.5MPa it yields 402N push and 345N pull; neighbouring bores like the 40mm offer 628N push if more force is required. The 240mm stroke exceeds 300mm? No, but for general guidance ensure side-load alignment to prevent rod bending. Air cushions only decelerate; use a pilot check valve or the SAIL/BSAI lock variant to hold loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X240
- ✓ 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 SI32X240 FAQ
Yes, the SI32X240 is discontinued. The direct replacement is the SAI32X240. It shares the same ISO 15552 mounting interface, 32mm bore, 240mm stroke, output force, G1/8 port, and accessories, fitting existing fixtures perfectly.
It has a G1/8 port. The force ratings are: 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.
