This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X280U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X280U 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 MAL25X280U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 280mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X280U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280U
The AirTAC MAL25X280U is a discontinued compact double-acting aluminum mini round cylinder featuring a 25mm bore and 280mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa. AirTAC ended this series, replacing it with the MBL25X280U, which serves as a drop-in replacement retaining the exact bore, stroke, force, G1/8 port, and flat-end rear cover.
This legacy unit features a fixed rubber bumper rather than an adjustable cushion, and its front and rear covers are threaded onto the barrel, unlike the riveted rolling-packed body of the current MBL. Because this specific SKU lacks the -S magnet option, it cannot accept any position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, while the carbon-steel rod has a 20 µm hard chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X280U 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 MBL25X280U 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 MAL25X280U Is Used
PCB shuttle routing
Drives a 280mm stroke shuttle board between SMT pick-and-place machines using 245N push force at 0.5 MPa.
Carton flap folder
Folds small corrugated carton flaps in tight packaging lanes where the 25mm compact body fits easily.
Textile yarn guide
Shifts a yarn guide carriage across a knitting head, relying on the 10mm hard-chrome rod for smooth extension.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280U with MBL25X280U
To replace the MAL25X280U, order the MBL25X280U and confirm your 25mm bore, 280mm stroke, PT thread, G1/8 port, and U flat-end back cover. If you need to step down to a smaller bore, the 20mm version offers 157N push at 0.5 MPa; stepping up to the 32mm bore yields 402N push. Since this SKU has no -S magnet, you cannot mount a sensor; if position detection is needed, upgrade to an MBL25X280US and use the current CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M. At 280mm stroke, the 10mm rod is vulnerable to bending under side loads, so use a U flat-end rigid mount with an external guide rail. Remember that a plain MAL/MBL does not hold its load if air pressure drops; add an external rod lock for vertical safety. If end-of-stroke cushioning is critical, choose the MBLC variant for its adjustable air cushion.
Upgrade checklist
- ✓ Order the MBL25X280U (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 MBL25X280U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X280U FAQ
Yes, the MAL25X280U is discontinued. The exact drop-in replacement is the MBL25X280U, which matches the 25mm bore, 280mm stroke, 245N push force at 0.5 MPa, G1/8 port, and U flat-end mounting.
The 25mm bore delivers 245N push and 206N pull at 0.5 MPa, 343N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific MAL25X280U SKU lacks the -S magnet, it cannot accept a position sensor.
