This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32BX30S, 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 SI32BX30S
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX30S
The AirTAC SI32BX30S is a discontinued double-acting ISO 15552 profile cylinder featuring a SUS304 stainless steel rod and a 30 mm stroke. Delivering 402 N push force at 0.5 MPa, it is directly replaced by the SAI32BX30S. This drop-in upgrade shares the exact G1/8 port, M10x1.25 thread, and mounting interface, fitting existing fixtures seamlessly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. For your 402 N output, expect a safe working load of roughly 241 N or a 20 kg vertical lift with a 2:1 margin. The SAI family also adds SAIL, SAIF, and BSAI lock variants absent in the SI line. Your -S magnet supports legacy CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX30S 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 SAI32BX30S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX30S Is Used
Compact Part Ejection
Uses the 30 mm stroke and 402 N force to push small machined components out of a fixture reliably.
Stainless Rod Sorting
The SUS304 rod resists corrosion in washdown environments while deflecting light parts along a guide.
Small Valve Actuation
Short stroke movement to toggle process valves where a 20 kg vertical lift margin is sufficient.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX30S with the SAI32BX30S
To replace the discontinued SI32BX30S, order the SAI32BX30S keeping the identical 32 mm bore, 30 mm stroke, -S magnet, and SUS304 rod. Verify the ISO 15552 mounting accessory and G1/8 port. Sizing both ways: this bore yields 402 N push at 0.5 MPa, whereas a neighbouring 40 mm bore offers 628 N. Note that a plain cylinder drifts on air loss as the cushion only decelerates; for load holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX30S
- ✓ 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 SI32BX30S FAQ
Yes, the SI32BX30S is discontinued. The exact drop-in replacement is the SAI32BX30S, which maintains the identical ISO 15552 mounting interface, 32 mm bore, 30 mm stroke, output force, and G1/8 port.
It features a G1/8 port and provides 402 N push / 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum force of 82 kgf at 1.0 MPa.
