This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X300-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X300-S-CM 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 MAL40X300-S-CM (Discontinued) -> MBL40X300-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X300-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300-S-CM is a discontinued double-acting aluminum mini round cylinder. It features a 40mm bore, a 300mm stroke, a built-in magnet (-S), and a CM round-end back cover. As the strongest bore in the MAL mini series, it delivers 628 N of push force and 528 N of pull force at 0.5 MPa. AirTAC ended this line, so the exact drop-in replacement is the MBL40X300-S-CM, which matches the original bore, stroke, output force, G1/4 port, and CM mounting profile.
The legacy MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for structural rigidity. This specific SKU includes a magnet for position sensing; the older MAL works with CS1-M or DS1-M reed switches, but upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor family. The 16mm carbon-steel rod has a 20-micron hard chrome plating, and the piston relies on a heterogeneous two-way seal that retains grease for long-term friction reduction.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X300-S-CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X300-S-CM 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.

Actuates a 300mm diverting gate on a packaging conveyor, using the 628 N push force at 0.5 MPa to reliably shift heavy loaded pallets onto a secondary track.
Opens and closes a 300mm stroke safety door on a CNC lathe, where the CM round-end back cover provides the pivot needed to handle slight mechanical misalignments during travel.
Folds large corrugated cardboard flaps on a heavy-duty case erector, leveraging the 128 kgf maximum theoretical force to overcome stiff packaging material resistance.
To replace the MAL40X300-S-CM, order the MBL40X300-S-CM. Verify that your existing setup uses the default PT tapered port thread, the CM round-end back cover, and the -S magnet. When upgrading, note that your existing CS1-M or DS1-M sensors will not mount to the MBL; you must switch to the CMSG, DMSG, or EMSG switch family. If your application requires an adjustable air cushion at the end of stroke, the fixed rubber bumper on the MAL cannot be tuned; you should step up to the MBLC variant on the current line instead.
When sizing, step down to the 32mm bore if you need less force (402 N push at 0.5 MPa), or step up to a larger ISO 15552 profile cylinder if you need more power, as 40mm is the maximum bore in this mini series. Because this is a 300mm stroke, the 16mm rod is vulnerable to bending under lateral stress; use an external guide rail or a pivot mount to absorb any arcing loads. Finally, a plain bumper does not lock the rod; if air pressure drops, the load will drift, so add an external rod lock or pilot-operated check valve for fail-safe holding.
Upgrade checklist
Yes, the MAL40X300-S-CM is discontinued. The exact drop-in replacement is the MBL40X300-S-CM. It matches the 40mm bore, 300mm stroke, G1/4 port, CM round-end back cover, and mounting dimensions. The MBL body uses a riveted rolling-packed design instead of threaded covers, and you must upgrade your position sensors from the old CS1-M/DS1-M to the current CMSG/DMSG/EMSG family.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. The operating speed ranges from 30 to 800 mm/s, operating pressure is 0.1-1.0 MPa, and it uses a fixed rubber bumper for end-of-stroke deceleration.
