This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAI32BX900 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAI32BX900 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 SI32BX900
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 900mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX900
The AirTAC SI32BX900 is a discontinued double-acting ISO 15552 profile cylinder featuring a 32mm bore, 900mm stroke, SUS304 stainless steel rod, and a G1/8 port. Delivering 402N push force at 0.5MPa, it is replaced by the SAI32BX900. This drop-in successor matches the exact bore, stroke, force, port, and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. For this bore, safe working load is roughly 241N (about 60% of the 402N push force) with a vertical lift capacity near 20kg at a 2:1 margin. Note this SKU lacks a magnet (-S) and cannot accept CS1-B/DS1-B sensors. The cushion only decelerates; use a pilot check valve for load holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX900 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 SAI32BX900 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 SI32BX900 Is Used
Long-Reach Transfer
Drives 900mm stroke push actions on light materials where the 402N force at 0.5MPa is sufficient for horizontal movement.
Stainless Rod Washdown
The SUS304 rod option suits light industrial environments needing corrosion resistance over a 900mm extension length.
Vertical Lift Guiding
Handles vertical lifts up to roughly 20kg with a 2:1 safety margin, requiring external guides to prevent side-load bending.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX900 with the SAI32BX900
To replace the discontinued SI32BX900, order the SAI32BX900, confirming the ISO 15552 mounting interface, 32mm bore, 900mm stroke, G1/8 port, and SUS304 rod. Because this 900mm stroke is long, use external guides to prevent rod bending and side-load damage. If downsizing to a 40mm bore is considered, the 40mm option yields 628N push at 0.5MPa. This non-magnetic SKU cannot take a sensor. For load holding on air loss, the cushion will not lock; use an external rod lock or pilot check valve, or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX900
- ✓ 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 SI32BX900 FAQ
Yes, the SI32BX900 is discontinued. The exact drop-in replacement is the SAI32BX900. It shares the identical ISO 15552 mounting interface, 32mm bore, 900mm stroke, force, G1/8 port, and SUS304 rod material, fitting existing fixtures perfectly.
The G1/8 port bore delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa with a 27mm adjustable cushion.
