This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL25X275U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL25X275U 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 MAL25X275U
The AirTAC Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 275mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL25X275U, which matches its bore, stroke, force and mounting.

About the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275U
The AirTAC MAL25X275U is a discontinued double-acting aluminum mini round cylinder with a 25 mm bore and 275 mm stroke. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. AirTAC replaced this legacy unit with the MBL25X275U, a drop-in alternative retaining the exact same G1/8 port, 10 mm rod, and flat-end U back cover. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor.
Two structural details define this actuator. First, the original MAL body relies on threaded front and rear covers, whereas the modern MBL replacement uses a riveted rolling-packed assembly for faster production. Second, the piston relies on a heterogeneous two-way seal that retains grease, running against a carbon-steel rod plated with 20 um of hard chrome to resist wear in compact machinery.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL25X275U 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 MBL25X275U 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 MAL25X275U Is Used
PCB Conveyor Routing
Pushes routing gates along a 275 mm path in electronics assembly lines, utilizing the 245 N push force to divert bare boards without damaging fragile traces.
Server Chassis Ejection
Extracts hot-swap server drives from tight rack enclosures, where the compact 25 mm aluminum body fits between dense cable channels and the U flat-end cover mounts flush.
Carton Flap Folding
Folds secondary cardboard flaps on small packaging lines, relying on the 206 N pull force to retract the arm clear of the product before sealing.
Replacing the Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275U with MBL25X275U
To replace the MAL25X275U, order the MBL25X275U. Verify your 10 mm rod-end thread (M10x1.25), the default PT tapered port form, and the rigid U flat-end back cover before installing. If your mechanism requires end-of-stroke cushioning, note that the MAL uses a fixed rubber bumper; you must step up to the current-line MBLC for an adjustable air cushion. Furthermore, a plain bumper does not hold the load if air pressure drops, so add an external rod lock for vertical safety.
At 275 mm of travel, the 10 mm rod is vulnerable to bending under lateral stress; use an external guide rail to prevent side-load damage. For sizing flexibility, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N at the same pressure.
Upgrade checklist
- ✓ Order the MBL25X275U (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 MBL25X275U instead of this discontinued model.
Airtac MAL25 Aluminum Alloy Mini Cylinder MAL25X275U FAQ
Yes, the MAL25X275U is discontinued. The exact drop-in replacement is the MBL25X275U, which matches the 25 mm bore, 275 mm stroke, G1/8 port, and U back cover. The MBL upgrades the body to a riveted rolling-packed design but maintains the same force ratings.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. Note that this SKU has no -S magnet, so it cannot support position sensors.
