This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X320SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X320SU 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 MAL25X320SU
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320SU 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 MBL25X320SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320SU
The AirTAC MAL25X320SU is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 320mm stroke, delivering 245N of push force at 0.5MPa. AirTAC replaced this legacy unit with the MBL25X320SU, a drop-in alternative that preserves the exact bore, stroke, output force, G1/8 port, and U flat-end rear cover. You can swap the old cylinder out without changing your mounting layout or plumbing.
This SKU includes a built-in magnet (-S) for position detection; note that the legacy MAL works with older CS1-M or DS1-M reed switches, while the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. The original MAL body features threaded front and back covers, whereas the updated MBL uses a riveted rolling-packed body. Both designs rely on a fixed rubber bumper at the stroke ends, meaning there is no adjustable air cushion on this model.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X320SU 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 MBL25X320SU 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 MAL25X320SU Is Used
PCB Conveyor Diverter
Pushes lightweight populated boards sideways on a 320mm travel path; the 245N push force at 0.5MPa is sufficient to slide the panels without damaging delicate solder joints.
Carton Labeling Gate
Extends 320mm to block and position small cardboard cartons for a labeling head, relying on the compact 25mm round body to fit within tight conveyor side-frame clearances.
Small Part Ejection Arm
Actuates a 320mm ejection lever to clear machined small parts from a CNC chuck, using the -S magnet to confirm full retraction before the next machining cycle begins.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320SU with MBL25X320SU
To replace the MAL25X320SU, order the MBL25X320SU. Confirm your 10mm rod thread (M10x1.25), G1/8 port, and the rigid U flat-end back cover are retained in the new unit. Because this SKU has the -S magnet, you must also upgrade your position sensing from the old CS1-M / DS1-M switches to the modern CMSG / DMSG / EMSG series. If your application requires adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant on the current line, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to a 20mm bore reduces the push force to 157N at 0.5MPa, while stepping up to a 32mm bore increases it to 402N. With a 320mm stroke on a relatively small 10mm rod, side-load tolerance is low; you should use an external guide rail to prevent rod bending, or pivot the rigid U cover to a clevis mount if arcing motion is unavoidable. Remember that a plain double-acting cylinder drifts when air pressure is lost, so add an external rod lock if the load must be held vertically.
Upgrade checklist
- ✓ Order the MBL25X320SU (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 MBL25X320SU instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X320SU FAQ
Yes, the MAL25X320SU is discontinued. The exact drop-in replacement is the MBL25X320SU. It offers the same 25mm bore, 320mm stroke, G1/8 port, U flat-end back cover, and mounting footprint. The only change is the body construction (riveted rolling-packed on the MBL versus threaded covers on the MAL) and the sensor family.
The 25mm bore provides a push force of 245N and a pull force of 206N at 0.5MPa, a push force of 343N at 0.7MPa, and a maximum theoretical force of 50kgf at 1.0MPa. Because this model includes the -S magnet, it supports position sensing; the legacy MAL uses CS1-M or DS1-M switches, while the MBL replacement requires CMSG, DMSG, or EMSG sensors.
