This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X140SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X140SU 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 MAL25X140SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140SU 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 MBL25X140SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140SU
The AirTAC MAL25X140SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 140mm stroke. It delivers 245N of push force and 206N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X140SU, which matches the bore, stroke, output force, G1/8 port, and U flat-end back cover. You can order the MBL equivalent today to keep your machinery running without modifying the mounting setup.
This legacy SKU features a built-in magnet (-S) for position detection, originally designed to work with CS1-M or DS1-M reed switches. When upgrading to the MBL series, you must switch to the current CMSG, DMSG, or EMSG sensor family. Another key structural change is the body construction: the older MAL uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance. The 10mm carbon-steel rod features 20um hard-chrome plating, and the piston relies on a heterogeneous two-way seal that retains grease for long-term lubrication.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X140SU 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 MBL25X140SU 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 MAL25X140SU Is Used
PCB Depaneling Router
Provides 245N of push force at 0.5 MPa to separate routed printed circuit boards, utilizing the 140mm stroke to clear the cutting spindle during tool changes.
Pouch Spacing Diverter
Uses the U flat-end rigid back cover to firmly anchor a diverter arm on a packaging line, pushing pouches at 30-800 mm/s to maintain proper pitch.
Tray Stacking Separator
Actuates a 140mm stroke to insert a separator plate between stacked product trays, relying on the grease-retaining two-way seal for continuous smooth operation.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140SU with MBL25X140SU
To replace the MAL25X140SU, order the MBL25X140SU, ensuring you keep the U flat-end back cover for rigid mounting and the built-in magnet (-S). Remember that the MBL upgrade requires modern CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors. If your application requires an adjustable air cushion at the end of stroke, note that the MAL only has a fixed rubber bumper; you would need to specify the MBLC variant on the current line instead.
When sizing this cylinder, verify if 245N push at 0.5 MPa is sufficient. If you need less force, step down to the 20mm bore (157N push), or if you need more power, step up to the 32mm bore (402N push). Because the stroke is 140mm, be mindful of side-load tolerance; the 10mm rod has low bending resistance, so an external guide rail is recommended to prevent premature seal wear. Finally, a plain MAL or MBL does not hold its load when air pressure is lost—the rod will drift—so add an external rod lock or pilot-operated check valve if position holding is critical.
Upgrade checklist
- ✓ Order the MBL25X140SU (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 MBL25X140SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X140SU FAQ
Yes, the MAL25X140SU is discontinued. The exact drop-in replacement is the MBL25X140SU, which offers the same 25mm bore, 140mm stroke, 245N push force, G1/8 port, and U flat-end back cover. You can order the MBL25X140SU as a direct substitute.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this model includes a magnet (-S), it works with CS1-M or DS1-M switches on the MAL, but the MBL replacement requires CMSG, DMSG, or EMSG sensors.
