This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X650-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X650-S-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 MAL40X650-S-U (Discontinued) -> MBL40X650-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 650mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X650-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X650-S-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and a 650mm stroke. Because 650mm exceeds the 500mm standard maximum, this unit was a made-to-order non-standard stroke. It delivers a robust 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X650-S-U, which matches the bore, stroke, force, port, and mounting layout perfectly.
This legacy SKU features a built-in magnet (-S) for position sensing and a U-style flat-end back cover for rigid rear mounting. The original MAL body used threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Additionally, the MAL -S magnet interfaces with the older CS1-M and DS1-M reed switches; upgrading to the MBL40X650-S-U means adopting the current CMSG, DMSG, or EMSG sensor family. The MAL relies on a fixed rubber bumper for end-of-stroke damping, while the current MBLC line offers an adjustable air cushion.

The MBL40X650-S-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.

Uses the 628N push force at 0.5MPa to reliably deflect heavy cardboard cartons on a packaging line, while the 650mm stroke provides the long reach needed to clear wide conveyor belts.
Drives a sliding machine tool safety door, relying on the rigid U flat-end back cover to maintain alignment and the -S magnet to confirm door closure for the safety interlock.
Ejects completed layer assemblies from a palletizing station, where the 880N thrust at 0.7MPa easily overcomes friction without needing a larger profile cylinder.
To replace the MAL40X650-S-U, order the MBL40X650-S-U and verify your setup: it retains the 40mm bore, 650mm stroke, G1/4 port, PT thread form, U flat-end back cover, and -S magnet. If your application requires a cushioned end-of-stroke stop rather than the fixed rubber bumper, step up to the MBLC40 equivalent. Because this is a 650mm stroke, side-load tolerance is critical; the 16mm carbon-steel rod with 20um hard chrome plating is highly susceptible to bending under lateral stress. You must use an external guide rail, a pivot mounting accessory, or the double-rod MBLD equivalent to prevent premature seal wear from rod drift.
When sizing this cylinder, you can step down to the 32mm bore (which yields 402N push at 0.5MPa) if your load is lighter and you need a smaller footprint. Conversely, if you need more force, note that 40mm is the largest bore in this mini-round family, so exceeding it requires moving to a larger ISO 15552 profile cylinder. Remember that a plain MBL does not hold its position when air pressure is lost; for vertical loads, add an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL40X650-S-U, which offers the same 40mm bore, 650mm stroke, 628N push force, G1/4 port, and U flat-end mounting. The MBL uses a riveted rolling-packed body instead of threaded covers, and its -S magnet requires upgrading from the old CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG sensor family.
The MAL40X650-S-U operates on filtered air at 0.1-1.0MPa with a speed range of 30-800mm/s. It features a 16mm rod, an M12x1.25 rod-end thread, and a G1/4 port. The thrust figures are 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. Note that the 650mm stroke is a non-standard made-to-order length exceeding the 500mm standard maximum.
