This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X400-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X400-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 MAL40X400-U (Discontinued) -> MBL40X400-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 400mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X400-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X400-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 400mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and a 16mm carbon-steel rod with 20um hard-chrome plating. Because this SKU lacks the -S magnet option, it cannot support any position sensing. The direct drop-in replacement is the MBL40X400-U, which matches the original bore, stroke, output force, port size, and flat-end U back cover exactly.
A key upgrade in the MBL is the riveted rolling-packed body, which replaces the threaded front and back covers found on this legacy MAL. Both cylinders use a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable cushion; if your 400mm stroke requires precise damping, you should step up to the current MBLC line. The MAL relies on a self-lubricating front-cover bearing guide and a heterogeneous two-way seal that retains grease to maximize component life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X400-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X400-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.

Actuates a routing flap on a conveyor handling large fiberglass panels, using the 628N push force at 0.5MPa to reliably shift heavy boards into a testing lane.
Pushes packed appliance cardboard cartons along a roller bed, utilizing the 400mm stroke to clear the packaging area for the next cycle.
Provides secondary ejection of molded plastic tubs from a tool cavity, where the 528N pull force safely retracts the 16mm rod after the part clears the mold.
To replace the MAL40X400-U, order the MBL40X400-U. Confirm your 40mm bore, 400mm stroke, G1/4 port, PT thread, and the rigid flat-end U back cover. Since this model has no -S magnet, you cannot mount a sensor; if you need position detection, order an MBL40X400-SU instead, which upgrades you to the modern CMSG, DMSG, or EMSG switch family (the legacy MAL used CS1-M or DS1-M sensors). If you need adjustable air cushioning instead of a fixed rubber bumper, specify the MBLC series.
When sizing, you can step down to the 32mm bore (402N push at 0.5MPa) if your load is lighter, or step up to a larger ISO 15552 profile cylinder if you need more than 128kgf at 1.0MPa. Because this is a 400mm stroke, the 16mm rod is highly susceptible to bending under side-loads; use an external guide rail or a pivot mount. A plain MBL does not hold its position when air is lost—the rod drifts—so add an external rod lock or pilot-operated check valve for fail-safe load holding.
Upgrade checklist
Yes, the MAL40X400-U is discontinued. The exact drop-in replacement is the MBL40X400-U, which provides the same 40mm bore, 400mm stroke, 628N push force at 0.5MPa, G1/4 port, and flat-end U back cover. The MBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
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. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion; for adjustable air cushioning, use the current MBLC line.
