This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X42, 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 SI32X42
The AirTAC SI32 Standard Air Cylinder SI32X42 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 42mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X42, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X42
The AirTAC SI32X42 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 42mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X42. This direct upgrade retains the exact interface, bore, stroke, force and mounting.
The SAI32X42 features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this non-magnet SKU cannot take a sensor; legacy CS1-B/DS1-B switches only fit the -S version.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X42 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 SAI32X42 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 SI32X42 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture using its 402N thrust at 0.5MPa.
Clamp Actuation
Provides reliable holding force for small pneumatic clamps in compact assembly jigs.
Gate Diversion
Drives short-stroke diverter gates on packaging lines with a fast 30-800mm/s speed range.
Replacing the Airtac SI32 Standard Air Cylinder SI32X42 with the SAI32X42
To replace the SI32X42, order the SAI32X42. Confirm the ISO 15552 mounting interface, 32mm bore, 42mm stroke, G1/8 port (PT/G/NPT thread), and your mounting accessory (LB, FA, TC). This non-magnet SKU cannot accept a sensor; if position detection is needed, select an SAI32X42S and use current AirTAC switches. If less force is acceptable, a 25mm bore offers lower thrust; stepping up to a 40mm bore provides 628N. Remember, a plain cylinder drifts on air loss; for load holding, use the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X42
- ✓ 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 SI32X42 FAQ
Yes, the SI32X42 is discontinued. The direct replacement is the AirTAC SAI32X42. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 42mm stroke, output force, G1/8 port and mounting fixtures.
This double-acting cylinder has a 12mm rod, M10x1.25 thread, 27mm cushion, and G1/8 port. Force ratings are: 402N push / 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a max force of 82kgf at 1.0MPa. Operating speed is 30-800mm/s.
