This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X450-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X450-U 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 MAL25X450-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 450mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X450-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-U
The AirTAC MAL25X450-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 450mm stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa. Featuring a U flat-end back cover and a G1/8 port, it uses a Ø10mm carbon-steel rod with 20um hard chrome plating. The exact drop-in replacement is the MBL25X450-U, matching the bore, stroke, output force, and mounting.
This legacy unit lacks a magnet (-S), meaning it cannot support any position sensing. If sensing is needed on the replacement, an MBL25X450-US with CMSG/DMSG/EMSG switches is required. The MAL uses a threaded front and rear cover, whereas the modern MBL features a riveted rolling-packed body. Both rely on a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion. The internal heterogeneous two-way seal retains grease for long-term friction reduction.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X450-U 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 MBL25X450-U 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 MAL25X450-U Is Used
PCB conveyor gating
Pushes a 450mm travel gate to divert circuit boards on a tight electronics assembly line using 245N of push force at 0.5MPa.
Carton flap folding
Extends a 450mm arm to fold secondary packaging flaps on a compact filling machine, relying on the rigid U flat-end cover.
Small part ejection
Ejects lightweight molded plastic parts from a press over a 450mm distance, utilizing the self-lubricating front-cover bearing guide.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-U with MBL25X450-U
To replace the MAL25X450-U, order the MBL25X450-U to retain the exact 25mm bore, 450mm stroke, G1/8 port, and U flat-end cover. Because this SKU lacks an -S magnet, it cannot accept a CS1-M or DS1-M sensor; the MBL replacement also requires the -S suffix to use modern CMSG/DMSG/EMSG switches. If your cycle speed demands adjustable air cushioning rather than a fixed rubber bumper, step up to the MBLC25X450-U on the current line.
For sizing flexibility, stepping down to the 20mm bore yields 157N push at 0.5MPa, while stepping up to the 32mm bore provides 402N. At 450mm, the 10mm rod is highly susceptible to bending under side loads; use an external guide rail or a pivot mounting accessory. A plain cylinder does not hold its load when air pressure drops, so fit an external rod lock for vertical safety.
Upgrade checklist
- ✓ Order the MBL25X450-U (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 MBL25X450-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X450-U FAQ
Yes, the MAL25X450-U is discontinued. The exact drop-in replacement is the MBL25X450-U, offering the same 25mm bore, 450mm stroke, 245N push force at 0.5MPa, G1/8 port, and U flat-end mounting.
At 0.5MPa it provides 245N push and 206N pull force; at 0.7MPa it provides 343N push, with a maximum theoretical force of 50kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept CS1-M or DS1-M position sensors.
