This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X130S, 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 SI32X130S
The AirTAC SI32 Standard Air Cylinder SI32X130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 130mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X130S
The AirTAC SI32X130S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 130 mm stroke. It delivers 402 N push force at 0.5 MPa via a G1/8 port. The direct replacement is the SAI32X130S, which matches the ISO 15552 mounting interface, bore, stroke, force, port and mounting hardware exactly.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SI-S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF and BSAI lock variants.

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 SAI32X130S 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 SI32X130S Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight machined components out of a fixture on an automated line.
Package Diverting
Actuates a routing gate for small parcels, where the 130 mm stroke provides just enough travel to redirect flow without占用 excessive space.
Replacing the Airtac SI32 Standard Air Cylinder SI32X130S with the SAI32X130S
To replace the SI32X130S, order the SAI32X130S. Verify the ISO 15552 mounting interface, 130 mm stroke, G1/8 port (PT/G/NPT thread options) and your mounting accessory (LB, FA, TC, etc.). The -S suffix means a magnet for CS1-B/DS1-B sensors; the SAI uses current AirTAC switches. Sizing both ways: a 40 mm bore offers 628 N push at 0.5 MPa, while dropping to 0.3 MPa yields about 241 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use a pilot check valve or SAIL lock for held loads. At 130 mm stroke, guide external rods to prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X130S
- ✓ 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 SI32X130S FAQ
Yes, the SI32X130S is discontinued. The direct replacement is the SAI32X130S. It is dimensionally interchangeable per ISO 15552, keeping the same 32 mm bore, 130 mm stroke, output force, G1/8 port and mounting interface.
This double-acting cylinder has a G1/8 port. The thrust 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 theoretical max of 82 kgf at 1.0 MPa.
