This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAI32BX600S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAI32BX600S 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 SI32BX600S
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 600mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX600S
The AirTAC SI32BX600S is a discontinued double-acting ISO 15552 profile cylinder featuring a 32mm bore, 600mm stroke, and a SUS304 stainless steel rod. Delivering 402 N of push force at 0.5 MPa, it is replaced drop-in by the SAI32BX600S, which shares the exact same ISO 15552 mounting interface, port size, and output force. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
With a 600mm extension, this long-stroke actuator requires external guides to prevent rod bending under side loads. The -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family uses current AirTAC switches. For load holding, note that the air cushion only decelerates; use an external pilot check valve or the SAIL lock variant, as standard cylinders drift without live air. A computed buyer insight: safe working load is roughly 241 N (60% of 402 N), yielding a 20 kg vertical lift capacity with a 2:1 margin.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX600S 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 SAI32BX600S 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 SI32BX600S Is Used
Light-Part Diversion
Pushes small packages on a 600mm line using 402 N force, with the SUS304 rod resisting humid washdown environments.
Vertical Lowering
Lowers 20 kg fixtures with a 2:1 safety margin, requiring an external guide to handle the 600mm stroke side loads.
Compact Ejection
Ejects light parts from fixtures using the G1/8 ported actuator, relying on the magnet for end-of-stroke confirmation.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX600S with the SAI32BX600S
To replace the SI32BX600S, order the SAI32BX600S. Verify the ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/8 port thread, and the -S magnet for position sensing. The SUS304 rod (-B) offers corrosion resistance over standard carbon steel. For sizing, this 32mm bore yields 402 N push at 0.5 MPa; if more force is needed, step up to the 40mm bore (628 N). Because the 600mm stroke exceeds 300mm, use external guides to prevent rod bending. For drop prevention, a plain cylinder drifts on air loss; select the SAIL air-released lock or BSAI clamp-lock variant if holding is required.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX600S
- ✓ 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 SI32BX600S FAQ
Yes, the SI32BX600S is discontinued. The exact drop-in replacement is the SAI32BX600S. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 600mm stroke, G1/8 port, and mounting interface, but adds an upgraded two Y-shaped one-way piston seal for longer life.
The 32mm bore features a G1/8 air port and an M10x1.25 rod thread. Force ratings are: 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The safe working load is approximately 241 N.
