This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X275U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X275U 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 MAL40X275U (Discontinued) -> MBL40X275U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 275mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X275U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X275U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 275mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, placing it in the heavy-duty class for compact pneumatics. AirTAC ended production of the MAL line, replacing it with the MBL40X275U. The MBL is a drop-in upgrade retaining the exact 275mm stroke, G1/4 port, and 128kgf maximum force, so it bolts right into your existing jig.
This legacy SKU features a U flat-end back cover for rigid rear mounting and uses the default PT tapered thread form. Because this specific model lacks the -S magnet option, it cannot accept a position sensor. The original MAL body used threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both designs rely on a fixed rubber bumper to soften end-of-stroke impacts, though an adjustable air cushion is available if you step up to the MBLC variant.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X275U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X275U 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, fitting neatly into tight mold bases where larger profile cylinders cannot fit.
Drives a 275mm stroke routing gate on a compact packaging conveyor, using the U flat-end cover for rigid mounting against the machine frame to handle carton traffic.
Folds heavy cardboard flaps on a case packing line, relying on the 880N push force available at 0.7MPa to cleanly crease thick corrugated material.
To replace the MAL40X275U, order the MBL40X275U, confirming the 40mm bore, 275mm stroke, G1/4 port, and U flat-end back cover. Since this SKU has no -S magnet, it cannot hold a sensor; if you need position detection on the new unit, specify an MBL40X275US and note that the modern switch family changes from the legacy CS1-M/DS1-M to the current CMSG/DMSG/EMSG. The fixed rubber bumper is not a lock; the rod will drift if air pressure drops, so add an external rod lock for vertical loads.
If you need to step down, the 32mm bore neighbor provides 402N push at 0.5MPa. If you need more force, 40mm is the largest available mini round size in this family. At 275mm of stroke, the 16mm rod is highly susceptible to bending under side loads; use an external guide rail or a pivot mount to prevent premature seal wear.
Upgrade checklist
Yes, the MAL40X275U is discontinued. The exact drop-in replacement is the MBL40X275U, which shares the same 40mm bore, 275mm stroke, G1/4 port, and U flat-end mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The 40mm bore generates 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
