This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X20U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X20U 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 MAL25X20U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 20mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X20U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20U
The AirTAC MAL25X20U is a discontinued compact double-acting aluminum mini round cylinder with a 20mm stroke. It delivers a 245N push and 206N pull at 0.5MPa using a G1/8 port. Because this legacy model is end-of-life, you should order the drop-in MBL25X20U replacement, which matches the bore, stroke, force, port and U flat-end back cover exactly.
This SKU lacks the -S magnet, meaning it cannot accept a position sensor. The original MAL features threaded front and back covers, whereas the MBL replacement uses a riveted rolling-packed body. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod has 20um hard chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X20U 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 MBL25X20U 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 MAL25X20U Is Used
PCB Depaneling Saw
Cycles a 245N push at 0.5MPa to feed a depaneling router blade through printed circuit boards in tight electronics assembly cells.
Bottle Deflector Arm
Uses the 20mm stroke to snap a deflector gate outward, diverting small plastic bottles on a packaging conveyor line.
Small Parts Ejector
Kicks lightweight molded plastic parts out of an injection mold cavity using the 206N pull force at 0.5MPa.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20U with MBL25X20U
To replace the MAL25X20U, order the MBL25X20U. Verify your 25mm bore, 20mm stroke, G1/8 port, and default PT tapered thread. The U flat-end back cover provides a rigid rear mount. If you need a position sensor, this non-magnet SKU will not work; you must select an MBL25X25S equivalent instead. The MBL uses CMSG/DMSG/EMSG switches rather than the older CS1-M/DS1-M family.
For sizing flexibility, stepping down to the 20mm bore drops the push force to 157N at 0.5MPa, while stepping up to the 32mm bore increases it to 402N. Note that the fixed rubber bumper softens end-of-stroke impact but is not an adjustable cushion; for adjustable air cushioning, look at the MBLC variant. This cylinder does not hold its load when air pressure is lost.
Upgrade checklist
- ✓ Order the MBL25X20U (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 MBL25X20U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X20U FAQ
Yes, the MAL25X20U is discontinued. The exact drop-in replacement is the MBL25X20U, which offers the same 25mm bore, 20mm stroke, 245N push force at 0.5MPa, G1/8 port, and U flat-end back cover.
At 0.5MPa the push force is 245N and the pull force is 206N. At 0.7MPa the push force is 343N. The maximum theoretical force is 50kgf at 1.0MPa.
