This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X150-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X150-S-U in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X150-S-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X150-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X150-S-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X150-S-U
The AirTAC MAL32X150-S-U is a discontinued double-acting aluminum mini round cylinder featuring a 32mm bore and 150mm stroke. It delivers a robust 402N of push force and 346N of pull force at 0.5MPa, making it suitable for medium-duty compact actuation. The exact drop-in replacement is the MBL32X150-S-U, which matches the bore, stroke, output force, G1/8 port, and mounting dimensions perfectly.
This legacy SKU includes a built-in magnet (-S) for position sensing and a U flat-end back cover for rigid rear mounting. The original MAL body utilized threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for enhanced structural integrity. The internal piston relies on a heterogeneous two-way seal that retains grease, and the Ø12mm carbon-steel rod is protected by 20µm hard-chrome plating to resist wear. The MAL relies on a fixed rubber bumper to soften end-of-stroke impacts; it is not an adjustable cushion, nor does it hold the load when air pressure is lost.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X150-S-U carries the same 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 MBL32X150-S-U 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 MAL32 Aluminum Alloy Mini Air Cylinder MAL32X150-S-U Is Used
PCB Conveyor Diverter
Pushes lightweight fiber-optic routing gates on a PCB assembly line using its 402N push force at 0.5MPa, fitting easily into tight machine frames.
Chip Tray Ejector
Extends 150mm to push silicon wafer trays out of a testing station, relying on the -S magnet to trigger the next stage via a sensor.
Small Parts Sorter
Actuates a routing flap on a packaging conveyor to separate small plastic enclosures, benefiting from the rigid U flat-end rear mounting.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X150-S-U with MBL32X150-S-U
To replace the MAL32X150-S-U, order the MBL32X150-S-U and confirm the 32mm bore, 150mm stroke, G1/8 port, and PT thread form. You must also account for the -S magnet: the legacy MAL works with the older CS1-M and DS1-M reed switches, but the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The U flat-end back cover provides a rigid rear mounting point, so ensure your frame is square to the rod to avoid binding. If your application requires an adjustable air cushion to slow down the 150mm travel, step up to the MBLC variant on the current line, as the MAL only offers a fixed rubber bumper.
When sizing, you can step down to the 25mm bore (delivering 245N push at 0.5MPa) for lighter loads, or step up to the 40mm bore (delivering 628N push at 0.5MPa) for heavier work. Because this unit features a 150mm stroke, the small Ø12mm rod has limited tolerance for side loads; use an external guide rail or a pivot mount to prevent rod bending. Remember that a plain bumper does not lock the rod—if you need to hold a load vertically during an air loss event, install an external pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL32X150-S-U (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the MBL32X150-S-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X150-S-U FAQ
Yes, the MAL32X150-S-U is discontinued. The exact drop-in replacement is the MBL32X150-S-U, offering the same 32mm bore, 150mm stroke, force, G1/8 port, and U flat-end mounting. The MBL upgrades the body from threaded covers to a riveted rolling-packed design, and if you use the -S magnet, you must switch from the older CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG sensors.
The 32mm bore provides a push force of 402N and a pull force of 346N at 0.5MPa, and a push force of 563N at 0.7MPa. The maximum theoretical force is 82kgf at 1.0MPa. The port size is G1/8, and it uses a Ø12mm carbon-steel rod with an M10x1.25 rod-end thread.
