This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X250-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X250-CM 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-CM (Discontinued) -> MBL40X250-CM 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-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X250-CM is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 250mm stroke, delivering 628N push and 528N pull force at 0.5MPa. The exact drop-in replacement is the MBL40X250-CM, matching the bore, stroke, force, G1/4 port, and CM round-end mounting. Because this SKU lacks a magnet, it cannot accept a position sensor. The legacy MAL uses threaded front and back covers, whereas the MBL upgrade features a riveted rolling-packed body for equally robust performance.
Internally, the carbon-steel rod has 20um hard-chrome plating guided by a self-lubricating front-cover bearing. The piston relies on a heterogeneous two-way seal that retains grease. This cylinder uses a fixed rubber bumper to soften end-of-stroke impacts; if your application requires adjustable cushioning, the current-line MBLC variant offers that feature, as the MAL never did.

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

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

Halts 40mm aluminum pallet profiles on a 90-degree transfer chain conveyor using 628N of push force at 0.5MPa.
Acts as a secondary pusher to index 16mm steel bar stock into the collet, relying on the 250mm stroke length.
Folds heavy corrugated cardboard side flaps prior to tape sealing, utilizing the CM round-end to pivot smoothly during motion.
To replace the MAL40X250-CM, order the MBL40X250-CM, ensuring you keep the PT tapered port thread, the G1/4 port size, and the CM round-end back cover. Since this specific SKU has no -S magnet, it cannot support a CS1-M or DS1-M sensor; if position detection is needed, move to an MBL equivalent with the S suffix, which uses the modern CMSG, DMSG, or EMSG switch families. At 250mm of stroke, the 16mm rod is susceptible to bending under side loads, so utilize the CM round-end to accommodate arcing motions or add an external guide.
For sizing flexibility, stepping down to the 32mm bore yields 402N push force at 0.5MPa, while stepping up is unavailable as 40mm is the largest standard MAL mini round bore. Remember that a plain MBL does not hold its position when air pressure is lost; the rod will drift. For load holding, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X250-CM is discontinued. The exact drop-in replacement is the MBL40X250-CM, which shares the same 40mm bore, 250mm stroke, 628N push force, G1/4 port, and CM round-end mounting. The MBL upgrades the body to a riveted rolling-packed design from the older threaded covers.
At 0.5MPa, the push force is 628N and pull is 528N; at 0.7MPa push is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. This specific SKU lacks a magnet, so it cannot accept a position sensor; adding an S to the MBL replacement enables CMSG, DMSG, or EMSG switches.
