This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL40X350U, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL40X350-U (Discontinued) -> MBL40X350-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 350mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL40X350-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X350-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 350mm stroke. It delivers a robust 628N push and 528N pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. Because this legacy series is end-of-life, AirTAC now supplies the MBL40X350-U as the direct replacement, matching the original bore, stroke, output force, port size, and mounting footprint for seamless integration.\n
This specific SKU includes a U flat-end back cover for rigid rear mounting and lacks a built-in magnet, meaning it cannot support position sensing. Unlike the older MAL body that used threaded front and back covers, the modern MBL replacement features a riveted rolling-packed body for equal structural integrity. The original MAL cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts, whereas the current MBL line offers an adjustable air cushion option (MBLC) for heavier loads. Furthermore, the carbon-steel rod with 20um hard chrome plating is paired with a heterogeneous two-way seal that retains grease, supported by a self-lubricating front-cover bearing guide.

Provides 628N of push force at 0.5MPa to eject small plastic parts from mold cavities, utilizing the 350mm stroke to fully clear the machine platen.
Shifts a diverter arm along a packaging line to route small boxes, with the U flat-end cover providing rigid stability against sudden lateral impacts.
Drives a mechanical folding blade on a case erector to tuck minor flaps before adhesive application, relying on the self-lubricating bearing for 800mm/s operation.
To replace the MAL40X350-U, order the MBL40X350-U. Verify your installation requires the U flat-end back cover for rigid mounting and confirm the 350mm stroke fits your spatial envelope. If your machine needs position feedback, this specific no-magnet SKU cannot accept a sensor; you must upgrade to an MBL40X350-S model, which transitions you from the legacy CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG sensor family. The 40mm bore uses a G1/4 port and M12x1.25 rod thread. If you need to step down, the 32mm bore yields 402N push at 0.5MPa; if you need more power, note that 40mm is the largest available bore in this mini cylinder family. At 350mm stroke, the 16mm rod is highly susceptible to bending under side loads, so an external guide rail or a pivot mount is strongly recommended to prevent premature seal failure. Remember that the fixed rubber bumper is not a lock; the rod will drift if air pressure is lost, so add an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X350-U is discontinued. The direct replacement is the MBL40X350-U, which offers the same 40mm bore, 350mm stroke, 628N push force at 0.5MPa, G1/4 port, and U flat-end mounting. The main upgrade is the body construction, shifting from threaded covers to a riveted rolling-packed assembly.
At 0.5MPa, the 40mm bore provides 628N push and 528N pull force, increasing to 880N push at 0.7MPa, with a theoretical maximum of 128kgf at 1.0MPa. This specific SKU has no -S magnet, so it cannot accept CS1-M or DS1-M position sensors; for sensing, you must specify an MBL40X350-S and use CMSG/DMSG/EMSG switches.
