This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X400-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X400-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 MAL25 Aluminum Alloy Mini Cylinder MAL25X400-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X400-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-U
The AirTAC MAL25X400-U is a discontinued double-acting aluminum mini round cylinder featuring a 25mm bore and 400mm stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL25X400-U, which matches the bore, stroke, output force, port size, and flat-end mounting. The legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for structural rigidity.
This specific SKU includes a U flat-end back cover for rigid rear mounting and lacks a built-in magnet (-S), meaning it cannot accept a position sensor. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod with 20um hard chrome plating slides through a self-lubricating front-cover bearing guide. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X400-U 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 MBL25X400-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 MAL25 Aluminum Alloy Mini Cylinder MAL25X400-U Is Used
PCB Router Ejection
Pushes routed printed circuit boards out of a routing machine over a 400mm travel, using the 245N push force to clear the cutting bed without damaging the panel.
Carton Flap Folder
Folds small corrugated carton flaps during case packing, relying on the rigid U flat-end back cover to withstand repeated axial impact over the long 400mm extension.
Pallet Diverter Gate
Actuates a routing flap on a modular conveyor to divert small product trays, where the 206N pull force safely retracts the 10mm rod against the gate spring.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-U with MBL25X400-U
To replace the MAL25X400-U, order the MBL25X400-U. Confirm the 25mm bore, 400mm stroke, G1/8 port, default PT tapered thread, and the U flat-end back cover. Because this SKU lacks the -S magnet, it cannot support a position sensor; if you need position feedback, step up to the MBL25X400S-U and use the current CMSG, DMSG, or EMSG switches instead of the discontinued CS1-M or DS1-M.
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. A plain MAL/MBL does not hold its load when air is lost; the rod will drift, so use an external rod lock for vertical loads. Because the 400mm stroke paired with a 10mm rod has low side-load tolerance, use an external guide rail or a pivot mount to prevent rod bending. If end-of-stroke impact is too harsh, upgrade to the MBLC for an adjustable air cushion.
Upgrade checklist
- ✓ Order the MBL25X400-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 MBL25X400-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X400-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X400-U, which offers the same 25mm bore, 400mm stroke, 245N push force at 0.5MPa, G1/8 port, and U flat-end mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
At 0.5MPa, the push force is 245N and the pull force is 206N. At 0.7MPa, the push force is 343N. The maximum theoretical force is 50kgf at 1.0MPa. Operating pressure is 0.1-1.0MPa, speed is 30-800mm/s, and it uses a fixed rubber bumper rather than an adjustable cushion.
