This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X127SN, 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 SI32X127SN
The AirTAC SI32 Standard Air Cylinder SI32X127SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 127mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X127SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X127SN
The AirTAC SI32X127SN is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 127 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. AirTAC replaced this legacy unit with the SAI32X127SN, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, output force, and port size. Note that 127 mm is a nonstandard stroke length.
The SAI upgrade features a refined piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. This SI unit includes a magnet for legacy CS1-B/DS1-B sensors and an NBR seal rated for -20 to +70 C (Viton H raises this to 150 C). The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line.

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 SAI32X127SN 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 SI32X127SN Is Used
Package Diverting
Sort small boxes on a line with a 127 mm nonstandard stroke, providing a 20 kg vertical lift margin.
Clamp Actuation
Secures workpieces during light machining, relying on the 402 N push force at 0.5 MPa operating pressure.
Replacing the Airtac SI32 Standard Air Cylinder SI32X127SN with the SAI32X127SN
To replace the discontinued SI32X127SN, order the SAI32X127SN. Verify your ISO 15552 mounting fixture, the 32 mm bore, the 127 mm nonstandard stroke, and the G1/8 port (available in PT, G, or NPT). The -S denotes a piston magnet for CS1-B/DS1-B switches, and -N specifies the NBR seal. If you need more force, the neighboring 40 mm bore yields 628 N push at 0.5 MPa; if less is required, consider a smaller profile. Because this is a nonstandard 127 mm stroke, ensure your guiding handles side loads to prevent rod bending. A plain cylinder drifts without live air, so for load holding use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X127SN
- ✓ 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 SI32X127SN FAQ
Yes, the AirTAC SI32X127SN is discontinued. The direct replacement is the SAI32X127SN. It shares the identical ISO 15552 mounting interface, 32 mm bore, 127 mm stroke, force, and G1/8 port, fitting directly into existing fixtures.
The 32 mm bore uses a G1/8 port. Force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
