This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X375U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X375U 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 MAL40X375U (Discontinued) → MBL40X375U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 375mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X375U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X375U is a discontinued double-acting aluminum mini round cylinder featuring a 40 mm bore and 375 mm stroke. Delivering 628 N of push force at 0.5 MPa, it is replaced directly by the MBL40X375U. This drop-in successor matches the exact bore, stroke, output force, G1/4 port, and U flat-end rear cover for a seamless retrofit. The original MAL relied on threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for structural rigidity.
Because this specific SKU lacks an -S magnet, it cannot accept a position sensor. The internal mechanics include a fixed rubber bumper to soften end-of-stroke impacts and a heterogeneous two-way seal that retains grease. Note that the bumper is not an adjustable air cushion; if your application requires end-of-stroke deceleration tuning, the current-line MBLC variant provides that feature.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X375U 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 MBL40X375U 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.

Pushes 15 kg cardboard cartons off a main conveyor belt using 628 N of thrust at 0.5 MPa, with the 375 mm stroke reaching across the lane.
Actuates a heavy sliding safety door on a CNC turning center, utilizing the G1/4 port for rapid air flow and the rigid U flat-end cover for stable mounting.
Folds large corrugated box flaps during automated case sealing, where the fixed rubber bumper absorbs the impact at the end of the 375 mm extension.
To replace the MAL40X375U, order the MBL40X375U. Confirm the 40 mm bore, 375 mm stroke, PT tapered port thread, and the U flat-end back cover. If you need to adjust the force, stepping down to a 32 mm bore yields 402 N push at 0.5 MPa, while stepping up to a 50 mm profile cylinder provides significantly higher thrust. At 375 mm of stroke, the 16 mm carbon-steel rod is susceptible to bending under lateral stress; use an external guide rail or a pivot mount to manage side loads. This non-magnet SKU cannot support a sensor, but if you upgrade to an -S model, note that the legacy CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG sensors on the MBL. A plain bumper does not hold the load if air pressure drops; add a pilot-operated check valve for position holding.
Upgrade checklist
Yes, the MAL40X375U is discontinued. The exact drop-in replacement is the AirTAC MBL40X375U, which shares the identical 40 mm bore, 375 mm stroke, G1/4 port, and U flat-end mounting. The main physical change is that the MBL uses a riveted rolling-packed body instead of the MAL's threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa operating pressure.
