This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X140U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X140U 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 MAL25X140U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 140mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X140U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140U
The AirTAC MAL25X140U is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and 140mm stroke. It delivers 245N push and 206N pull at 0.5MPa through a G1/8 port with an M10x1.25 rod-end thread. AirTAC replaced this unit with the MBL25X140U, a drop-in alternative retaining the exact bore, stroke, output force, port size, and flat-end rear mounting.
Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept a position sensor. The original MAL uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-stroke impact absorption, a heterogeneous two-way grease-retaining piston seal, and a carbon-steel rod with 20um hard-chrome plating.

| Stroke | 140 mm |
| Acting type | Double acting |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X140U 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 MBL25X140U 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 MAL25X140U Is Used
PCB Depaneling Router
Cycles a routing blade at 140mm to singulate populated FR4 boards, utilizing the 245N push force to maintain clean cuts without flexing the carbon-steel rod.
Bottling Line Diverter
Pushes small PET containers onto a secondary packaging lane, where the U flat-end cover provides rigid rear mounting to handle 206N pull during retraction.
Carton Flap Folder
Actuates a mechanical flap-folding arm at 140mm stroke, relying on the self-lubricating front-cover bearing to sustain high-speed 30-800mm/s cycles.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140U with MBL25X140U
To replace the MAL25X140U, order the MBL25X140U. Confirm the 140mm stroke, G1/8 port, PT thread form, and U flat-end back cover. Since this unit has no -S magnet, it cannot support a sensor; if position detection is needed, order the MBL25X140US and note that the modern switch family changes to CMSG, DMSG, or EMSG. If a cushion is required for the 140mm travel, the current-line MBLC offers an adjustable air cushion the MAL never had.
For sizing flexibility, stepping down to the 20mm bore yields 157N push at 0.5MPa, while stepping up to the 32mm bore provides 402N push. The 140mm stroke exceeds 100mm, so the 10mm rod is susceptible to bending under lateral stress; use an external guide rail or pivot mount to absorb side loads. A plain bumper softens impact but does not lock the rod—if air pressure drops, the load will drift, requiring an external pilot-operated check valve for position holding.
Upgrade checklist
- ✓ Order the MBL25X140U (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 MBL25X140U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140U FAQ
Yes, the MAL25X140U is discontinued. The exact drop-in replacement is the MBL25X140U, which matches the 25mm bore, 140mm stroke, G1/8 port, and U flat-end cover. The MBL uses a riveted rolling-packed body instead of the threaded covers on the MAL.
At 0.5MPa it provides 245N push and 206N pull, 343N push at 0.7MPa, and a maximum theoretical force of 50kgf at 1.0MPa. This specific SKU lacks the -S magnet, so it cannot accept CS1-M or DS1-M position sensors.
