This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAI32BX35 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAI32BX35 in place of this model. 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 SI32BX35
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX35 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 35mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX35, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX35
The AirTAC SI32BX35 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore, 35 mm stroke, and a SUS304 stainless piston rod. It delivers 402 N push force at 0.5 MPa via a G1/8 port. The direct drop-in replacement is the SAI32BX35, which shares identical ISO 15552 mounting dimensions, output force, and cushioning for seamless fixture integration.
Upgrading to the SAI32BX35 brings an advanced piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For this bore class, the safe working load is roughly 241 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 20 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, meaning it cannot accept position sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX35 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 SAI32BX35 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 SI32BX35 Is Used
Stainless Rod Clamping
Ideal for small part clamping in machining fixtures where the SUS304 rod resists corrosion from cutting fluids.
Compact Ejection
Provides reliable 402 N push force at 0.5 MPa for ejecting lightweight molded components from assembly jigs.
Material Diverting
Suitable for actuating small diverters on packaging lines, offering fast 30-800 mm/s cycling within a compact footprint.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX35 with the SAI32BX35
To replace the discontinued SI32BX35, order the SAI32BX35. Verify your ISO 15552 mounting interface, 32 mm bore, 35 mm stroke, G1/8 port thread, and SUS304 rod requirement. Because this SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, select an SAI32BX35S. For sizing alternatives, dropping to a smaller bore reduces force, while a larger bore increases it. If your application requires load holding on air loss, note that standard cylinders drift under pressure loss—the cushion only decelerates near stroke end. For secure holding, consider an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX35
- ✓ 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 SI32BX35 FAQ
Yes, the AirTAC SI32BX35 is discontinued. The exact drop-in replacement is the SAI32BX35. It features the same ISO 15552 mounting interface, 32 mm bore, 35 mm stroke, output force, and G1/8 port, fitting directly into existing fixtures.
This 32 mm bore cylinder uses a G1/8 air port. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. The rod end thread is M10x1.25.
