This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAI32BX750 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAI32BX750 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 SI32BX750
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX750 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 750mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX750, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX750
The AirTAC SI32BX750 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 750mm stroke. Featuring a SUS304 stainless piston rod for corrosion resistance, it delivers 402N push force at 0.5MPa. The direct drop-in replacement is the SAI32BX750, matching the G1/8 port, M10x1.25 thread, and mounting interface exactly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. For practical sizing, the safe working load is roughly 241N (60% of the 402N figure), yielding a 20kg vertical lift capacity with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. The SAI family also adds SAIL, SAIF, and BSAI lock variants absent in the SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX750 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 SAI32BX750 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 SI32BX750 Is Used
Corrosive Transfer
Ideal for pushing light components along washdown or chemical-grade conveyors where the SUS304 rod prevents rust.
Vertical Lift Gate
Raises and lowers lightweight access gates up to 750mm, safely handling loads around the 20kg vertical threshold.
Lab Positioning
Acts as a long-stroke linear actuator for testing fixtures, moving samples precisely in non-magnetic environments.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX750 with the SAI32BX750
To replace the SI32BX750, order the SAI32BX750. Confirm the ISO 15552 mounting interface, 32mm bore, 750mm stroke, G1/8 port, and your specific mounting accessory (LB, FA, TC, etc.). Because this SKU has no -S magnet, it cannot support position sensing; if switches are needed, specify a magnet on the SAI order. At 0.5MPa it yields 402N push and 345N pull; if undersized, the neighbouring 40mm bore provides 628N push. For the 750mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates; it does not hold load on air loss, so add a pilot check valve or consider the SAIL/BSAI lock variant for suspended loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX750
- ✓ 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 SI32BX750 FAQ
Yes, the SI32BX750 is discontinued. The exact drop-in replacement is the SAI32BX750. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 750mm stroke, output force, G1/8 port, and mounting interface to fit existing fixtures directly.
This 32mm bore cylinder uses a G1/8 air port. The thrust figures are 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa. It operates at 30-800mm/s with a 27mm adjustable cushion.
