This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X125-U-FA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X125-U-FA 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U-FA
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U-FA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X125-U-FA, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U-FA
The AirTAC MAL25X125-U-FA is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force at 0.5 MPa, it features a 25 mm bore, 125 mm stroke, and a G1/8 port. The exact drop-in replacement is the MBL25X125-U-FA, which matches the original bore, stroke, force, and FA flange mounting.
This legacy SKU features a U flat-end back cover for rigid rear mounting and a PT tapered port thread. Because this specific configuration lacks a magnet (-S), it cannot accept a position sensor. The original MAL body utilized threaded front and back covers, whereas the modern MBL replacement uses a riveted rolling-packed body for enhanced structural integrity. Both designs rely on a fixed rubber bumper to soften end-of-stroke impacts, meaning the rod will drift if air pressure is lost and the load is not externally locked.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X125-U-FA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The MBL25X125-U-FA 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 MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U-FA Is Used
PCB Router Z-Axis
Drives a light-duty Z-axis plunge on a desktop PCB router, utilizing the 245 N push force at 0.5 MPa to cleanly break through copper-clad laminates.
Carton Flap Folder
Folds small corrugated carton flaps on a compact packaging line, where the 125 mm stroke provides the exact travel needed to clear the product path.
Connector Insertion
Pushes micro USB connectors into PCB headers during automated assembly, relying on the self-lubricating front-cover bearing guide for smooth, low-friction motion.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U-FA with MBL25X125-U-FA
To replace the MAL25X125-U-FA, order the MBL25X125-U-FA, ensuring you retain the 25 mm bore, 125 mm stroke, G1/8 port, and FA flange mounting. If your application requires position sensing, note that this exact legacy SKU lacks a magnet and cannot hold a sensor; you must upgrade to an MBL25X125-S-U-FA and use the current CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are obsolete. If you need adjustable air cushioning rather than a fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to a 20 mm bore reduces thrust to 157 N push at 0.5 MPa, while stepping up to a 32 mm bore increases thrust to 402 N push at 0.5 MPa. Because this is a 125 mm stroke, the 10 mm carbon-steel rod with 20 um hard chrome plating has moderate side-load tolerance; ensure your FA flange mounting is perfectly aligned to prevent rod binding, and use an external guide for heavy offset loads.
Upgrade checklist
- ✓ Order the MBL25X125-U-FA (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 MBL25X125-U-FA instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X125-U-FA FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X125-U-FA, which offers identical bore, stroke, force, G1/8 port, and FA flange mounting. The modern MBL uses a riveted rolling-packed body instead of the older threaded covers, but performance remains the same.
At 0.5 MPa, the 25 mm bore provides 245 N push and 206 N pull force, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
