This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX170S, 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 SI32AX170S
The AirTAC SI32 Standard Air Cylinder SI32AX170S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX170S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32AX170S
The AirTAC SI32AX170S is a discontinued double-acting ISO 15552 profile cylinder featuring a 32mm bore, 170mm stroke, and a G1/8 port. Delivering 402N push force at 0.5MPa, it is replaced by the SAI32AX170S. This direct successor shares the exact ISO 15552 mounting interface, bore, and output force, fitting existing fixtures perfectly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SI32AX170S uses an SUS420J2 stainless rod (A option) and includes a magnet for CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX170S 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 | — |

Where the Airtac SI32 Standard Air Cylinder SI32AX170S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight molded parts out of a machining fixture.
Package Diverting
Actuates a routing gate on a packaging line, where the 170mm stroke provides precise movement.
Vertical Lift Stops
Raises a product stopper arm, safely handling loads around the 20kg vertical lift threshold.
Replacing the Airtac SI32 Standard Air Cylinder SI32AX170S with the SAI32AX170S
To replace the SI32AX170S, order the SAI32AX170S. Verify the ISO 15552 mounting interface, 32mm bore, 170mm stroke, G1/8 port, and the -S magnet for legacy CS1-B/DS1-B switches (the SAI uses current AirTAC switches). For higher force, the neighbouring 40mm bore provides 628N push at 0.5MPa. Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 170mm stroke, rod bending is low, but ensure guide alignment to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32AX170S
- ✓ 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 SI32AX170S FAQ
Yes, the SI32AX170S is discontinued. The direct replacement is the SAI32AX170S. It shares the same ISO 15552 mounting interface, 32mm bore, 170mm stroke, output force, and G1/8 port, fitting directly into existing setups.
This 32mm bore cylinder has a G1/8 port. It delivers a push force of 402N and pull of 345N at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
