This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X100TC, 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 SI32X100TC
The AirTAC SI32 Standard Air Cylinder SI32X100TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X100TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X100TC
The AirTAC SI32X100TC is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 100mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X100TC, matching the bore, stroke, force, port, and TC trunnion mount.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This no-magnet SKU cannot take a sensor, unlike the CS1-B/DS1-B compatible -S versions.

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 SAI32X100TC 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 SI32X100TC Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to push lightweight machined components out of a fixture on an automated line.
Package Diverting
Actuates a routing gate on a conveyor system, where the 100mm stroke provides just enough travel to redirect small boxes.
Clamp Actuation
Secures thin workpieces in a welding jig, taking advantage of the compact 32mm ISO 15552 profile barrel to fit tight cells.
Replacing the Airtac SI32 Standard Air Cylinder SI32X100TC with the SAI32X100TC
To replace the SI32X100TC, order the SAI32X100TC. Verify the ISO 15552 TC trunnion interface, 32mm bore, 100mm stroke, G1/8 port (PT/G/NPT thread options), and note this non-magnet SKU cannot accept a CS1-B/DS1-B sensor. Sizing both ways: the neighbouring 40mm bore yields 628N push at 0.5MPa, while dropping to 25mm stroke reduces rod extension. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve or the SAIL/BSAI lock variants. The SAIF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X100TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
