This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X50-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X50-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 MAL32X50-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X50-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X50-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X50-U
The AirTAC MAL32X50-U is a discontinued double-acting aluminum mini round cylinder with a 32mm bore and 50mm stroke. It delivers 402N of push force and 346N of pull force at 0.5MPa, utilizing a G1/8 port and a Ø12mm carbon-steel rod with 20um hard chrome plating. The U designation indicates a flat-end back cover for rigid mounting, while the self-lubricating front-cover bearing guide and heterogeneous two-way grease-retaining seal ensure long service life.
AirTAC replaced this legacy unit with the MBL32X50-U, a true drop-in replacement matching the exact bore, stroke, output force, port size, and mounting interface. The newer MBL upgrades the MAL's threaded front and back covers to a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor; if sensing is needed on the replacement, you must specify an MBL with an -S option to use the current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X50-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 MBL32X50-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 MAL32X50-U Is Used
Cardboard Box Flap Folder
Provides 402N of push at 0.5MPa to fold corrugated cardboard flaps on a packaging line, with the flat-end U cover providing rigid rear mounting against the machine frame.
CNC Lathe Door Latch
Actuates a sliding safety door on a CNC turning center, using the 50mm stroke to clear the work area for robotic bar feeders to load raw material.
PCB Test Fixture Clamp
Holds printed circuit boards securely during automated flying-probe electrical testing, where the self-lubricating bearing guide ensures smooth, stick-slip-free movement over thousands of cycles.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X50-U with MBL32X50-U
To replace the MAL32X50-U, order the MBL32X50-U, confirming the 32mm bore, 50mm stroke, G1/8 port, PT thread form, and U flat-end back cover. If your application requires end-of-stroke cushioning, note that the MAL relies on a fixed rubber bumper; for an adjustable air cushion, you must step up to the current-line MBLC equivalent. A plain MBL does not hold its load when air is lost—the rod will drift—so add an external rod lock or pilot-operated check valve for vertical or suspended loads.
For sizing flexibility, you can step down to the 25mm bore (providing 245N push at 0.5MPa) for lighter tasks, or step up to the 40mm bore (delivering 628N push at 0.5MPa) if you need more thrust. At a 50mm stroke, side-load risk is minimal, but the 12mm rod still has low bending tolerance, so avoid using the cylinder itself to absorb lateral off-center loads.
Upgrade checklist
- ✓ Order the MBL32X50-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 MBL32X50-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X50-U FAQ
Yes, the MAL32X50-U is discontinued. The exact drop-in replacement is the MBL32X50-U, which matches the 32mm bore, 50mm stroke, 402N push force, G1/8 port, and U flat-end mounting. The newer MBL uses a riveted rolling-packed body instead of the older threaded covers.
The force figures are: 402N push and 346N pull at 0.5MPa, 563N push at 0.7MPa, and a maximum theoretical force of 82kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; for sensing, order an MBL32X50-S to use CMSG/DMSG/EMSG switches.
