This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X80-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X80-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 MAL40X80-S-U (Discontinued) -> MBL40X80-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 80mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X80-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X80-S-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore, 80mm stroke, a U flat-end back cover, and a built-in magnet (-S). It delivers a robust 628N push force at 0.5MPa, utilizing a 16mm carbon-steel rod with 20um hard-chrome plating and a G1/4 port. AirTAC replaced this legacy unit with the MBL40X80-S-U, a drop-in alternative matching the exact bore, stroke, output force, port size, and mounting interface.
Buyers upgrading to the MBL40X80-S-U gain a riveted rolling-packed body, replacing the older MAL threaded front and back covers. The -S magnet on this legacy MAL functions with the older CS1-M and DS1-M reed switches, whereas the current MBL replacement utilizes the modern CMSG, DMSG, or EMSG sensor families. Both generations rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X80-S-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X80-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.

Provides 628N of push force at 0.5MPa to eject small plastic parts from injection molds, where the 80mm stroke and U flat-end rigid mounting ensure precise, straight-line ejection.
Actuates a routing gate on a 120-bottles-per-minute filling line, using the 16mm hard-chrome rod and 880N push force at 0.7MPa to reliably shift filled glass containers between lanes.
Drives a mechanical flap-folding arm on a case packing machine, where the 40mm bore delivers enough pull force (528N at 0.5MPa) to close heavy corrugated flaps before tape sealing.
To replace the discontinued MAL40X80-S-U, order the MBL40X80-S-U and verify your 40mm bore, 80mm stroke, G1/4 port, PT thread, U flat-end back cover, and -S magnet requirement. Because this SKU includes the -S magnet, you must upgrade your position sensing from the legacy CS1-M or DS1-M switches to the current CMSG, DMSG, or EMSG sensor family used by the MBL. If your application demands precise end-of-stroke deceleration rather than a fixed rubber bumper, step up to the current-line MBLC40X80-S-U which offers an adjustable air cushion the MAL never had.
For sizing flexibility, you can step down to the 32mm bore neighbor (providing 402N push at 0.5MPa) for lighter duties, or step up to the 50mm profile cylinder class for heavier loads. Note that a plain MAL or MBL cylinder does not hold its load when air pressure is lost; the rod will drift. For vertical loads, install an external pilot-operated check valve or a dedicated rod lock.
Upgrade checklist
Yes, the MAL40X80-S-U is discontinued. The exact drop-in replacement is the MBL40X80-S-U, which matches the 40mm bore, 80mm stroke, 628N push force, G1/4 port, and U flat-end mounting. You must upgrade your position sensors from the old CS1-M or DS1-M switches to the modern CMSG, DMSG, or EMSG family.
At 0.5MPa operating pressure, 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 features a 16mm rod, an M12x1.25 rod-end thread, a G1/4 port, and operates at speeds of 30-800mm/s.
