This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X250-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X250-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 MAL25X250-U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 250mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X250-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-U
The AirTAC MAL25X250-U is a discontinued double-acting aluminum mini round cylinder with a 25mm bore and 250mm stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa. AirTAC replaced this legacy unit with the MBL25X250-U, a drop-in alternative that matches the exact bore, stroke, output force, G1/8 port, and U flat-end mounting interface.
This SKU features a U flat-end back cover for rigid, non-articulating mounting and uses the default PT tapered port thread. Because it lacks an -S magnet, this specific cylinder cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the newer MBL utilizes a riveted rolling-packed body. Both share a fixed rubber bumper to soften end-of-stroke impacts, though neither acts as a lock to hold loads without air pressure.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X250-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 MBL25X250-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 MAL25X250-U Is Used
Carton Flap Folding
Uses the 245N push force at 0.5MPa to fold corrugated cardboard flaps on a packaging conveyor before tape sealing.
PCB Router Gate
Actuates a routing machine safety gate through the 250mm stroke, relying on the rigid U flat-end cover for a firm mount.
Parts Ejector Chute
Pushes machined aluminum parts down an ejection chute, where the fixed rubber bumper absorbs the repetitive end-of-stroke impact.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-U with MBL25X250-U
To replace this MAL25X250-U, order the MBL25X250-U. Verify your 25mm bore, 250mm stroke, G1/8 port, and the rigid U flat-end back cover. Since this SKU has no -S magnet, you cannot mount a sensor; if you need position detection on the new unit, add the S code and note that the MBL uses current CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. If you need an adjustable air cushion rather than the fixed rubber bumper, step up to the MBLC series.
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 250mm of stroke, the 10mm carbon-steel rod has limited side-load tolerance; use an external guide rail or a pivot mount to prevent rod bending. A plain cylinder drifts when air is lost, so add an external rod lock for suspended loads.
Upgrade checklist
- ✓ Order the MBL25X250-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 MBL25X250-U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X250-U FAQ
Yes, the MAL25X250-U is discontinued. The exact drop-in replacement is the MBL25X250-U, which provides the same 25mm bore, 250mm stroke, 245N push force at 0.5MPa, G1/8 port, and U flat-end cover. The new MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5MPa it provides 245N push and 206N pull force. At 0.7MPa the push force is 343N, with a theoretical maximum of 50kgf at 1.0MPa. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor.
