This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X101, 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 SI32X101
The AirTAC SI32 Standard Air Cylinder SI32X101 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 101mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X101, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X101
The AirTAC SI32X101 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 101 mm stroke. It delivers 402 N push and 345 N pull at 0.5 MPa through a G1/8 port. AirTAC replaced this legacy unit with the SAI32X101, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, stroke, force and port.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this SKU lacks a magnet (-S) so it cannot take a CS1-B/DS1-B sensor; the SAI family also adds SAIL, SAIF and BSAI variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X101 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 SAI32X101 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 SI32X101 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to eject small molded components from a fixture reliably.
Package Diverting
Diverts small cartons on a line, where the 20 kg vertical lift capacity handles product weight easily.
Replacing the Airtac SI32 Standard Air Cylinder SI32X101 with the SAI32X101
To replace this SI with the SAI32X101, confirm the ISO 15552 interface, 32 mm bore, 101 mm nonstandard stroke, G1/8 port (PT/G/NPT) and mounting accessory. Because 101 mm is a nonstandard stroke, expect a custom or extended lead time. Size both ways: a 40 mm bore gives 628 N push at 0.5 MPa, while dropping to a smaller bore reduces force. A plain cylinder does not hold load on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for holding. For any stroke over 300 mm, add a guide to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X101
- ✓ 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 SI32X101 FAQ
Yes, the SI32X101 is discontinued. The direct replacement is the SAI32X101, which shares the same ISO 15552 mounting interface, 32 mm bore, 101 mm stroke, force and G1/8 port.
This double-acting cylinder has a G1/8 port and provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa.
