This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X175-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X175-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 MAL40X175-U (Discontinued) -> MBL40X175-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 175mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X175-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X175-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 175mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and a Ø16mm carbon-steel rod with hard-chrome plating. The exact drop-in replacement is the MBL40X175-U, which matches the original bore, stroke, output force, port size, and U flat-end rear cover.
This legacy SKU uses a U flat-end back cover for rigid, non-articulating mounting, and because it lacks an -S code, it cannot accept a position sensor. The original MAL body relies on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both generations use a fixed rubber bumper rather than an adjustable cushion, though the current MBLC line offers an adjustable air cushion if end-of-stroke deceleration is required.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X175-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.

Pushes 15kg cardboard cartons off a powered roller conveyor using 628N of thrust at 0.5MPa, with the 175mm stroke clearing the adjacent belt lane.
Opens and closes a sliding safety guard on a horizontal machining center, relying on the rigid U flat-end rear cover to maintain parallel tracking without pivot sag.
Folds the lower side flaps of packing cases on a case erector, utilizing the fixed rubber bumper to soften the impact at the end of the 175mm extension.
To replace the MAL40X175-U, order the MBL40X175-U. Verify your 40mm bore, 175mm stroke, G1/4 port, and PT tapered thread form. The U flat-end back cover provides rigid alignment, so ensure your mounting face is square to prevent rod binding. If you need position detection, this specific non-magnet SKU cannot support it; an -S variant on the MBL line would be required, which also shifts the sensor family from the legacy CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches. If a cushion is needed to absorb kinetic energy, step up to the MBLC series, as the MAL bumper is fixed.
For sizing flexibility, the neighboring 32mm bore provides 402N of push force at 0.5MPa if your load is lighter, while no larger standard bore exists in this mini series, meaning you must transition to an ISO 15552 profile cylinder for higher force. Because the stroke is 175mm, the 16mm rod has limited side-load tolerance; use an external guide rail to prevent rod bending. Note that this cylinder drifts when air pressure is lost, so add an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X175-U is discontinued. The exact drop-in replacement is the MBL40X175-U, which provides the same 40mm bore, 175mm stroke, 628N push force at 0.5MPa, G1/4 port, and U flat-end mounting. The main physical change is that the original threaded body covers are replaced by a riveted rolling-packed body on the MBL.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it provides 880N push, with a theoretical maximum of 128kgf at 1.0MPa. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor; the -S variants on the MBL replacement use CMSG, DMSG, or EMSG switches.
