This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X250-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X250-S-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-S-U (Discontinued) -> MBL40X250-S-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-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X250-S-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 250mm stroke. It delivers a robust 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X250-S-U, which matches the bore, stroke, output force, port, and mounting accessories perfectly.
This legacy unit features a U flat-end back cover for rigid rear mounting and includes a built-in magnet (-S) for position detection. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Furthermore, the MAL -S magnet interfaces with the older CS1-M or DS1-M switches, while the MBL successor transitions to the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper and a heterogeneous two-way seal that retains grease for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X250-S-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X250-S-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.

Provides 628N of push at 0.5MPa to eject dense plastic parts from an injection molding fixture, utilizing the 250mm stroke to clear the mold base entirely.
Actuates a heavy-duty diverter gate on a packaging conveyor, where the G1/4 port supplies the air volume needed for rapid 30-800mm/s cycling across the 250mm travel.
Drives a mechanical arm to fold heavy corrugated carton flaps prior to sealing, benefiting from the rigid U flat-end rear mount to absorb offset reaction forces.
To replace the MAL40X250-S-U, order the MBL40X250-S-U. Confirm the 40mm bore, 250mm stroke, G1/4 port, and PT thread form are correct for your setup. Because this SKU includes the -S magnet, you must upgrade your sensors: the legacy CS1-M and DS1-M switches will not fit the new MBL body, so migrate to the CMSG, DMSG, or EMSG families. The U flat-end back cover provides rigid mounting, but if your machine experiences arcing loads, consider switching to the CA pivot clevis.
If you need to adjust the force, step down to the 32mm bore (402N push at 0.5MPa) or step up to a larger profile cylinder. At 250mm stroke, the 16mm carbon-steel rod is susceptible to side-load bending; use an external guide rail or a pivot mount to prevent seal wear. The fixed rubber bumper softens end-of-stroke impacts but does not lock the load—air loss causes rod drift. If adjustable cushioning is required, specify the MBLC variant on the current line instead of the standard MBL.
Upgrade checklist
Yes, the MAL40X250-S-U is discontinued. The exact drop-in replacement is the MBL40X250-S-U, which offers the same 40mm bore, 250mm stroke, 628N push force, and G1/4 port. The MBL uses a riveted body instead of threaded covers, and you must upgrade the -S magnet sensors from the old CS1-M/DS1-M to the modern CMSG/DMSG/EMSG family.
The 40mm bore carbon-steel rod is 16mm in diameter with an M12x1.25 rod-end thread. At 0.5MPa, it delivers 628N push and 528N pull. At 0.7MPa, the push force is 880N. The theoretical maximum force is 128kgf at 1.0MPa.
