This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX105S, 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 SI32BX105S
The AirTAC SI32 Standard Air Cylinder SI32BX105S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 105mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32BX105S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX105S
The AirTAC SI32BX105S is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore, 105 mm stroke, G1/8 port, and SUS304 stainless steel rod. It delivers 402 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI32BX105S, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, output force, and porting.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The -S magnet on this unit supports legacy CS1-B/DS1-B sensors, while the SAI family uses current AirTAC switches. The SAI line also introduces SAIL, SAIF, and BSAI lock or valve variants absent in the original SI series.

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 SAI32BX105S 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 SI32BX105S Is Used
Corrosive Environment Sorting
The SUS304 stainless steel rod makes this 32 mm bore unit suitable for diverting parts in washdown or mildly corrosive manufacturing settings.
Package Lane Routing
Provides reliable actuation for small pneumatic gates and pushers on packaging lines, delivering 402 N push force at 0.5 MPa.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX105S with the SAI32BX105S
To replace the SI32BX105S, order the SAI32BX105S and confirm the ISO 15552 mounting interface, 32 mm bore, 105 mm stroke, G1/8 port, and SUS304 rod option. The built-in magnet (-S) allows for position sensing. When sizing, note the 402 N push force at 0.5 MPa; if you need more force, the adjacent 40 mm bore yields 628 N. For load holding, remember a standard cylinder drifts without live air—the 27 mm adjustable cushion only decelerates at stroke end. Use an external pilot check valve or the SAIL/BSAI lock variant for secure holding. Since the 105 mm stroke is under 300 mm, side-load rod bending is minimal, but always verify guide alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX105S
- ✓ 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 SI32BX105S FAQ
Yes, the SI32BX105S is discontinued. The direct replacement is the SAI32BX105S. It shares the same ISO 15552 mounting interface, 32 mm bore, 105 mm stroke, G1/8 port, and force ratings, fitting existing fixtures perfectly.
At 0.5 MPa it provides 402 N push and 345 N pull force. At 0.7 MPa push is 563 N, and at 0.9 MPa it is 724 N. The theoretical max force is 82 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
