This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50-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 MAL40X50-U (Discontinued) → MBL40X50-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X50-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 50mm stroke. It delivers 628N push and 528N pull force at 0.5MPa, making it the highest thrust class in this compact series. AirTAC replaced this unit with the MBL40X50-U, a drop-in alternative retaining the exact 40mm bore, 50mm stroke, 880N push force at 0.7MPa, G1/4 port, and flat-end rear cover.
This legacy SKU features a U flat-end back cover for rigid mounting, and because it lacks the -S magnet option, it cannot support a position sensor. The original MAL body used threaded front and back covers on the barrel, whereas the current MBL replacement utilizes a riveted rolling-packed body for equivalent durability. Both generations rely on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X50-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 128 kgf | |
The MBL40X50-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 tight mold cavities where a compact 40mm bore is required.
Shifts lightweight pallets on a packaging line using its 50mm stroke and 528N pull force, fitting neatly into tight conveyor frame clearances.
Secures printed circuit boards for electrical testing, applying reliable 0.7MPa clamping thrust without overwhelming the delicate testing head assembly.
To replace the MAL40X50-U, order the MBL40X50-U and verify your PT tapered port thread, 50mm stroke, and the U flat-end back cover. If your machine requires end-of-stroke cushioning adjustment, step up to the MBLC series since the MAL only has a fixed rubber bumper. Because this SKU lacks the -S magnet, it cannot accept a sensor; if you need position feedback, order the MBL40X50S-U and note that the MBL family uses the newer CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M sensors.
For sizing flexibility, you can step down to the 32mm bore (402N push at 0.5MPa) if your application requires less thrust, or step up to larger ISO 15552 profile cylinders if you need significantly higher force. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost; the bumper softens the stroke end but does not lock the load. For vertical or suspended loads, add an external rod lock or pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X50-U is discontinued. The exact drop-in replacement is the MBL40X50-U, which matches the 40mm bore, 50mm stroke, G1/4 port, and U flat-end back cover. The MBL uses a riveted rolling-packed body instead of the original threaded covers.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. It uses a G1/4 port, a 16mm carbon-steel rod, and lacks a magnet, so it cannot support a position sensor.
