This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X325U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X325U 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 MAL25X325U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 325mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X325U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325U
The AirTAC MAL25X325U is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 325 mm stroke. It delivers 245 N push and 206 N pull force at 0.5 MPa. The exact drop-in replacement is the MBL25X325U, matching the bore, stroke, output force, G1/8 port and U flat-end cover. You simply swap the legacy unit for the current MBL model.
This SKU features a U flat-end back cover for rigid, non-pivoting mounting. Because this specific model lacks the -S magnet code, it cannot accept a position sensor. During the upgrade, note the structural change: the legacy MAL uses threaded front and back covers, while the modern MBL features a riveted rolling-packed body. The internal mechanics remain consistent, utilizing a heterogeneous two-way seal that retains grease alongside a carbon-steel rod with 20 um hard chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X325U 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 MBL25X325U 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 MAL25X325U Is Used
Pouch Transfer Arm
Pushes packaged pouches across a conveyor lane during a 325 mm transit cycle, utilizing the 245 N push force to overcome slide friction.
Carton Flap Folder
Actuates a mechanical folding arm to tuck cardboard flaps on a packing line, relying on the rigid U flat-end cover to resist offset forces.
Label Applicator Platen
Extends a label platen 325 mm to press adhesive labels onto curved bottles, needing the compact 25 mm body to fit within tight machine guarding.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325U with MBL25X325U
To replace the MAL25X325U, order the MBL25X325U. Confirm the 325 mm stroke, PT tapered port thread, and the U flat-end back cover. If you need position detection, you must step up to an -S designated SKU; note that the legacy MAL -S used CS1-M / DS1-M switches, whereas the MBL uses CMSG / DMSG / EMSG sensors. If 245 N push at 0.5 MPa is too much force, step down to the 20 mm bore (157 N push). If you need more power, step up to the 32 mm bore (402 N push).
At 325 mm of travel, the 10 mm rod is vulnerable to bending under side loads. Use an external guide rail to support the payload. The fixed rubber bumper softens end-of-stroke impacts but is not an adjustable cushion; for deceleration control, look at the MBLC variant on the current line. A plain cylinder does not hold position if air pressure drops, so add a pilot-operated check valve for load holding.
Upgrade checklist
- ✓ Order the MBL25X325U (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 MBL25X325U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X325U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X325U. It matches the 25 mm bore, 325 mm stroke, G1/8 port, and U flat-end cover. The main physical difference is the MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa push is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If you order the MBL -S version for sensing, it uses CMSG / DMSG / EMSG switches rather than the older CS1-M / DS1-M.
