This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X250-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X250-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).
The AirTAC AirTAC MAL40X250-U (Discontinued) -> MBL40X250-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 250mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X250-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X250-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 250mm stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa. AirTAC replaced this legacy series with the MBL40X250-U, a drop-in upgrade retaining the exact same bore, stroke, output force, G1/4 port, and U flat-end rear cover.
This specific SKU features a U flat-end back cover for rigid rear mounting and uses the default PT tapered port thread. Because it lacks the -S magnet option, this cylinder cannot accept a position sensor. During the upgrade, the older threaded front and back covers were replaced by a riveted rolling-packed body on the MBL. The internal piston relies on a heterogeneous two-way seal that retains grease, and the Ø16mm carbon-steel rod is protected by 20um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X250-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X250-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.

Actuates a routing flap on a packaging line conveyor, using the 628N push force to reliably shift heavy goods boxes onto a secondary track.
Opens and closes a heavy sliding machine tool safety door, where the 250mm stroke provides the exact travel distance needed for operator access.
Folds major bottom flaps on large corrugated cartons prior to tape sealing, taking advantage of the rigid U flat-end mount to hold alignment.
To replace the MAL40X250-U, order the MBL40X250-U. Verify your setup needs the U flat-end back cover, the default PT port thread, and the G1/4 port size. Because this SKU has no -S magnet, it cannot support a sensor; if you need position detection, step up to an MBL40X250-S-U and switch from the old CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG family. The MAL uses a fixed rubber bumper; if your application needs an adjustable air cushion, step up to the MBLC equivalent.
For sizing flexibility, you can step down to the 32mm bore (offering 402N push at 0.5 MPa) or step up if more force is required. At 250mm stroke, the Ø16mm rod is susceptible to bending under side loads; use an external guide rail or pivot mount to prevent premature seal wear. Remember that a plain double-acting cylinder drifts when air pressure is lost, so add an external rod lock if the load must be held vertically.
Upgrade checklist
Yes, the MAL40X250-U is discontinued. The exact drop-in replacement is the MBL40X250-U, which matches the 40mm bore, 250mm stroke, 628N force, G1/4 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design instead of the old threaded covers.
At 0.5 MPa it provides 628N push and 528N pull; at 0.7 MPa it provides 880N push, with a theoretical max of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If sensing is needed, order the -S version and use CS1-M/DS1-M switches, or switch to CMSG/DMSG/EMSG sensors on the MBL replacement.
