This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X550-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X550-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-CM (Discontinued) -> MBL40X550-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-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X550-CM is a discontinued double-acting aluminum mini round cylinder. As a 40mm bore unit, it delivers a push force of 628N and a pull force of 528N at 0.5MPa. It features a 550mm stroke, which exceeds the 500mm standard limit, making it a non-standard, made-to-order part. The exact drop-in replacement is the MBL40X550-CM, matching the bore, stroke, force, G1/4 port, and CM round-end cover.
This legacy unit uses a carbon-steel rod with 20um hard chrome plating and a heterogeneous two-way grease-retaining seal. The original MAL body uses threaded front and back covers, whereas the MBL upgrade features a riveted rolling-packed body. Because this SKU lacks the -S magnet, it cannot accept a position sensor. The cylinder relies on a fixed rubber bumper, not an adjustable cushion.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X550-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.

Drives a 550mm travel lifting gate on a printed circuit board conveyor, using the 628N push force to elevate the track assembly for layer routing.
Actuates a long-stroke cardboard carton pusher on a packaging line, where the CM round-end cover accommodates slight angular misalignment during the 550mm extension.
Moves an automated sample tray shuttle 550mm between testing stations in a clinical analyzer, relying on the self-lubricating bearing guide for smooth motion.
To replace the MAL40X550-CM, order the MBL40X550-CM. Verify the PT tapered port, the CM round-end back cover, and the 550mm non-standard stroke. If you need end-of-stroke cushioning, step up to the MBLC variant, as the MAL only has a fixed rubber bumper. Stepping down to the 32mm bore yields 402N push at 0.5MPa, while no larger bore exists in this mini series. The 550mm stroke on a 16mm rod demands an external guide or pivot to prevent rod bending.
A plain MBL cylinder does not hold its position when air pressure is lost. The rod will drift, and the bumper only softens the end of stroke. For a held load, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X550-CM is discontinued. The exact drop-in replacement is the MBL40X550-CM, which matches the 40mm bore, 550mm stroke, G1/4 port, and CM round-end cover. The MBL uses a riveted rolling-packed body instead of the threaded covers on the MAL.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it provides 880N push; the maximum theoretical force is 128kgf at 1.0MPa. Because this SKU lacks the -S magnet, it cannot accept a position sensor. The MBL replacement with an -S magnet uses CMSG, DMSG, or EMSG switches.
