This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX165, 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 SI32BX165
The AirTAC SI32 Standard Air Cylinder SI32BX165 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 165mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32BX165, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX165
The AirTAC SI32BX165 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 165mm stroke. Featuring a SUS304 stainless steel rod and G1/8 port, it delivers 402N push force at 0.5MPa. The direct replacement is the SAI32BX165, which shares the exact same ISO 15552 mounting interface, bore, stroke, output force, port size and accessories.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this specific SKU lacks a magnet (-S), it cannot accept a CS1-B/DS1-B sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX165 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 SI32BX165 Is Used
Small Part Transfer
Handles lightweight component positioning with 402N push force over a 165mm travel distance.
Packaging Gates
Actuates diverter flaps and small gates where a 20kg vertical lift capacity is sufficient.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX165 with the SAI32BX165
To replace the SI32BX165, order the SAI32BX165 and confirm the ISO 15552 interface, 32mm bore, 165mm stroke, G1/8 port, and SUS304 rod. Sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while dropping to a 25mm bore lowers force. This non-magnetic SKU cannot take a switch. For load holding, note that the cushion only decelerates; use an external rod lock or pilot check valve, or explore the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX165
- ✓ 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 SI32BX165 FAQ
Yes, the SI32BX165 is discontinued. The direct replacement is the SAI32BX165. It is dimensionally interchangeable per ISO 15552, keeping the same 32mm bore, 165mm stroke, force, G1/8 port and mounting fixtures.
The G1/8 port bore delivers a push of 402N and pull of 345N at 0.5MPa, 563N push at 0.7MPa, 724N at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
