This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X550-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X550-S-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 MAL40X550-S-CM (Discontinued) -> MBL40X550-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 550mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X550-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X550-S-CM is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 550mm stroke. Because 550mm exceeds the 500mm standard limit, this is a made-to-order non-standard stroke unit. It delivers 628N push and 528N pull force at 0.5MPa, peaking at 880N push at 0.7MPa. AirTAC replaced the MAL series with the MBL line, making the MBL40X550-S-CM your exact drop-in replacement. It matches the original bore, stroke, output force, G1/4 port, and mounting hardware exactly.
This legacy SKU includes a built-in magnet (-S) for position detection and a CM round-end back cover. The older MAL body used threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for structural rigidity. If you rely on the -S magnet, note that the legacy CS1-M and DS1-M switches do not carry over; the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The internal mechanics remain identical, utilizing a heterogeneous two-way grease-retaining seal and a carbon-steel rod with 20um hard-chrome plating.

The MBL40X550-S-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.

Uses the 880N push force at 0.7MPa to deflect heavy corrugated cartons on a sorting line, with the 550mm stroke reaching completely across the transport lane.
Leverages the CM round-end back cover to accommodate angular misalignment while shifting heavy fabric beams through the 550mm travel distance.
Relies on the 40mm bore's 628N thrust at 0.5MPa to push completed product layers onto wooden pallets inside a compact wrapping cell.
To replace this discontinued cylinder, order the MBL40X550-S-CM. Confirm your 40mm bore, 550mm non-standard stroke, G1/4 port, and PT thread form. The CM round-end back cover on this unit provides a smooth pivot interface for arcing motion paths. If you need to adjust your force output, stepping down to a 32mm bore drops the 0.5MPa push force to 402N, while no larger MAL/MBL mini round bore exists above 40mm. Because the 550mm stroke exceeds 300mm, the 16mm rod is highly susceptible to bending under side-loads; you must use an external guide rail or a pivot mounting accessory to prevent premature seal failure.
This model uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable air cushion. If your application requires adjustable cushioning for heavy loads, step up to the MBLC variant on the current line. Remember that the bumper is not a locking device; a plain MAL or MBL cylinder will drift if air pressure is lost, so add an external rod lock or pilot-operated check valve if you need to hold a vertical load safely.
Upgrade checklist
Yes, the MAL40X550-S-CM is discontinued. The exact drop-in replacement is the MBL40X550-S-CM, which matches the 40mm bore, 550mm stroke, G1/4 port, and CM round-end mounting. The MBL uses a riveted rolling-packed body instead of threaded covers, and if you use the -S magnet, you must upgrade from the old CS1-M / DS1-M switches to the modern CMSG / DMSG / EMSG sensors.
At 0.5MPa, the 40mm bore provides 628N of push force and 528N of pull force. At 0.7MPa, the push force increases to 880N, with a maximum theoretical force of 128kgf at 1.0MPa. It uses a 16mm carbon-steel rod with an M12x1.25 rod-end thread.
