This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X230SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X230SU 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 MAL40X230SU (Discontinued) -> MBL40X230SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 230mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X230SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X230SU is a discontinued double-acting aluminum mini round cylinder. Built for compact spaces, this 40 mm bore unit delivers 628 N of push force at 0.5 MPa. It features a built-in magnet (-S) for position sensing and a U flat-end back cover for rigid mounting. The exact drop-in replacement is the MBL40X230SU, matching the bore, stroke, force, G1/4 port, and mounting hardware.
Two engineering details distinguish this legacy unit. First, the original MAL body uses threaded front and rear covers, whereas the modern MBL replacement features a riveted rolling-packed body for faster assembly. Second, the -S magnet on this MAL works with the older CS1-M and DS1-M reed switches; upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20 um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X230SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X230SU 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 40 kg cardboard cartons off a narrow-belt conveyor using 628 N of thrust at 0.5 MPa, fitting into tight 40 mm frame gaps.
Opens and closes a heavy sliding safety shield on a CNC lathe, using the 230 mm stroke and the U flat-end cover for rigid, straight-line tracking.
Folds corrugated box flaps on an automated case erector, relying on the fixed rubber bumper to prevent denting the cardboard at end of stroke.
To replace the MAL40X230SU, order the MBL40X230SU. Confirm your 230 mm stroke, the G1/4 port, the default PT tapered thread form, the U flat-end back cover, and the magnet. Because the -S magnet is present, plan to swap your existing CS1-M or DS1-M switches for CMSG, DMSG, or EMSG sensors on the new MBL. If your application requires adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper.
At 230 mm of stroke, the 16 mm rod is susceptible to bending under lateral stress; use an external guide rail to support the load. If you need to step down, the 32 mm bore neighbor provides 402 N of push force at 0.5 MPa. If you need more power, note that 40 mm is the largest bore in this mini round family, so you would need to transition to a different ISO 15552 profile cylinder for higher force. Remember that the fixed rubber bumper softens the end of travel but does not hold the load; a plain MAL/MBL will drift if air pressure is lost, so add an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X230SU is discontinued. The exact drop-in replacement is the AirTAC MBL40X230SU. It provides the same 40 mm bore, 230 mm stroke, 628 N output force, G1/4 port, and U flat-end mounting. The primary change is that the MBL uses a riveted rolling-packed body instead of the threaded covers on the MAL, and if you use the -S magnet, you must upgrade from the old CS1-M or DS1-M switches to the current CMSG, DMSG, or EMSG sensors.
The 40 mm bore double-acting cylinder provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force is 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. It operates on filtered air at 0.1-1.0 MPa, runs at 30-800 mm/s, and has a 16 mm carbon-steel rod with an M12x1.25 thread.
