This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X320U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X320U 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 MAL25X320U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 320mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X320U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320U
The AirTAC MAL25X320U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 320mm stroke. It delivers 245N push and 206N pull at 0.5MPa. The exact drop-in replacement is the MBL25X320U, matching the bore, stroke, output force, G1/8 port, and U flat-end back cover. You can install the MBL without altering your existing mounting layout.
This legacy MAL features threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body. The cylinder uses a heterogeneous two-way seal that retains grease and a self-lubricating front-cover bearing guide. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X320U 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 MBL25X320U 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 MAL25X320U Is Used
PCB Conveyor Gate
Lifts a hinged conveyor section in a PCB assembly line, using the 245N push force at 0.5MPa to clear the 320mm vertical opening for operator passage.
Carton Flap Folder
Extends 320mm to fold the minor flaps of corrugated cartons on a packaging line, relying on the rigid U flat-end back cover to resist rearward shock.
Tool Ejector Station
Pushes a finished aluminum die-cast part out of a machining fixture, using the 206N pull force to retract the 10mm carbon-steel rod clear of the tool path.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320U with MBL25X320U
To replace the MAL25X320U, order the MBL25X320U. Verify your 10mm rod thread is M10x1.25 and your port is G1/8. The default PT tapered port thread and U flat-end rigid back cover carry over directly. If you need position sensing, you must step up to an MBL25X320US, which uses the modern CMSG, DMSG, or EMSG switches instead of the legacy CS1-M/DS1-M. If you require an adjustable air cushion to soften the 320mm travel, choose the MBLC25X320U, as the MAL only has a fixed rubber bumper.
For sizing flexibility, stepping down to a 20mm bore drops the 0.5MPa push force to 157N, while stepping up to a 32mm bore increases it to 402N. At 320mm of travel, the 10mm rod has low side-load tolerance; use an external guide rail or a pivot mount to prevent rod bending. A plain MBL does not hold a load if air pressure drops, so add an external rod lock for vertical applications.
Upgrade checklist
- ✓ Order the MBL25X320U (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 MBL25X320U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320U FAQ
Yes, the MAL25X320U is discontinued. The exact drop-in replacement is the MBL25X320U, offering the same 25mm bore, 320mm stroke, G1/8 port, and U flat-end back cover. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but mounting dimensions remain identical.
At 0.5MPa it provides 245N push and 206N pull; at 0.7MPa push is 343N, with a theoretical maximum of 50kgf at 1.0MPa. This specific SKU lacks a -S magnet, so it cannot accept CS1-M or DS1-M position sensors. If sensing is required, order the MBL25X320US and use current CMSG, DMSG, or EMSG switches.
