This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X40SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X40SU 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 MAL25X40SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X40SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40SU
The AirTAC MAL25X40SU is a discontinued compact double-acting aluminum mini round cylinder. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, it features a 25 mm bore, 40 mm stroke, and a G1/8 port. The exact drop-in replacement is the MBL25X40SU, which matches the original bore, stroke, output force, port size, and U flat-end mounting.
This legacy SKU includes a built-in magnet (-S) for position detection and a U flat-end back cover for rigid rear mounting. The original MAL body used threaded front and back covers, whereas the newer MBL utilizes a riveted rolling-packed body. Additionally, the -S magnet on this MAL works with older CS1-M or DS1-M reed switches, while the MBL replacement requires current CMSG, DMSG, or EMSG sensors. The piston relies on a heterogeneous two-way seal that retains grease, and the 10 mm carbon-steel rod features 20 μm hard-chrome plating for wear resistance.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X40SU 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 MBL25X40SU 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 MAL25X40SU Is Used
PCB Shuttle Guidance
Drives a 40 mm shuttle stroke in PCB routing machines, utilizing the 245 N push force to move lightweight panels between inspection stations.
Connector Insertion
Presses electronic connectors into motherboards where the 25 mm bore provides just enough force without damaging delicate components.
Carton Flap Folding
Folds small packaging flaps on compact cartoning lines, relying on the U flat-end cover for rigid, vibration-free rear mounting.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40SU with MBL25X40SU
To replace the MAL25X40SU, order the MBL25X40SU, ensuring you keep the 25 mm bore, 40 mm stroke, G1/8 PT thread, U flat-end back cover, and -S magnet. Because the -S magnet is present, plan to upgrade your sensing setup: the legacy CS1-M and DS1-M switches will not fit the MBL, so select modern CMSG, DMSG, or EMSG sensors. If your application requires adjustable end-of-stroke cushioning rather than the fixed rubber bumper found on both the MAL and standard MBL, step up to the MBLC variant on the current line.
For sizing flexibility, you can step down to the 20 mm bore (providing 157 N push at 0.5 MPa) for lighter loads, or step up to the 32 mm bore (delivering 402 N push at 0.5 MPa) for higher force demands. Remember that a plain double-acting cylinder does not hold its position or load when air pressure is lost; the rubber bumper only softens the stroke end and acts as no lock. For vertical loads, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
- ✓ Order the MBL25X40SU (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 MBL25X40SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X40SU FAQ
Yes, the MAL25X40SU is discontinued. The exact drop-in replacement is the MBL25X40SU, offering the same 25 mm bore, 40 mm stroke, 245 N push force at 0.5 MPa, G1/8 port, and U flat-end mounting.
At 0.5 MPa, the push force is 245 N and pull is 206 N; at 0.7 MPa push is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. The -S magnet works with older CS1-M or DS1-M switches, but the MBL25X40SU replacement requires CMSG, DMSG, or EMSG sensors.
