This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X150, 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 SI32X150
The AirTAC SI32 Standard Air Cylinder SI32X150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X150
The AirTAC SI32X150 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 150mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a G1/8 port. The direct replacement is the SAI32X150, matching the bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. This non-magnet SKU cannot take a sensor, unlike CS1-B/DS1-B equipped units. Viton H seals raise temps to 150C.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X150 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 SI32X150 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably eject small machined components from a fixture.
Package Diverting
Actuates a lightweight diverter arm on a packaging line, safely moving items without over-stressing the mechanism.
Clamp Actuation
Provides 345N pull force at 0.5MPa to close low-resistance clamps holding thin sheet metal during light assembly.
Replacing the Airtac SI32 Standard Air Cylinder SI32X150 with the SAI32X150
To replace the SI32X150, order the SAI32X150. Confirm the ISO 15552 interface, 150mm stroke, G1/8 port, M10x1.25 thread, and mounting accessory (LB, FA, TC, etc.). Because this is a non-S SKU, it cannot accept a magnetic sensor. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. At 150mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X150
- ✓ 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 SI32X150 FAQ
Yes, the SI32X150 is discontinued. The direct replacement is the SAI32X150. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 150mm stroke, output force, G1/8 port, and mounting interface.
This double-acting cylinder uses a G1/8 port and features an adjustable 27mm air cushion. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
