This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X450-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X450-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 MAL40X450-U (Discontinued) → MBL40X450-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 450mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X450-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X450-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 450mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The U suffix indicates a rigid flat-end back cover. Because this legacy series is end-of-life, the direct drop-in replacement is the MBL40X450-U, which matches the original bore, stroke, output force, port size, and mounting footprint exactly.
Two structural details stand out for maintenance planning. First, the original MAL body uses threaded front and back covers, whereas the modern MBL replacement employs a riveted rolling-packed body for enhanced structural integrity under pressure. Second, this specific SKU lacks a built-in magnet, meaning it cannot support any position sensing out of the box. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts, though it does not hold the load when air pressure is removed.

The MBL40X450-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.

Drives a folding mechanism on packaging lines, using the 628N push force at 0.5MPa to reliably close large corrugated cardboard flaps over a 450mm travel distance.
Pushes heavy product cartons across a transfer junction, where the 40mm bore provides enough thrust to overcome friction without stalling the sorting mechanism.
Raises and lowers a small woodworking router head, utilizing the flat-end U back cover for rigid mounting and the 450mm stroke to achieve full depth adjustment.
To replace the MAL40X450-U, order the MBL40X450-U. Verify that your application requires the 40mm bore generating 628N push at 0.5MPa. If you need to step down, the 32mm bore neighbor provides 402N push at 0.5MPa; if you need more power, note that 40mm is the largest available size in this mini round family, so exceeding 128kgf at 1.0MPa requires migrating to a different ISO profile cylinder. Since this SKU has no -S magnet, you cannot mount a CS1-M or DS1-M sensor; if position detection is required on the new unit, specify an MBL40X450-S-U and use the current CMSG, DMSG, or EMSG switch family. The fixed rubber bumper is not adjustable; if end-of-stroke deceleration is inadequate for a 450mm travel, upgrade to the MBLC version for an adjustable air cushion. Finally, a plain cylinder does not lock its position when air is lost, so a pilot-operated check valve is required to hold suspended loads safely.
At 450mm of travel, the 16mm carbon-steel rod is highly susceptible to side-load bending and sagging. To prevent premature seal failure, use an external linear guide or pair the cylinder with a pivot mount to absorb angular misalignment.
Upgrade checklist
Yes, the MAL40X450-U is discontinued. The exact drop-in replacement is the MBL40X450-U, which shares the same 40mm bore, 450mm stroke, G1/4 port, and flat-end U back cover. The modern MBL upgrades the body construction from threaded covers to a riveted rolling-packed assembly.
At 0.5MPa, the push force is 628N and the pull force is 528N. At 0.7MPa, the push force is 880N. The maximum theoretical force is 128kgf at 1.0MPa. This specific SKU lacks a magnet, so it cannot accept position sensors.
