This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X390SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X390SCA 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 MAL40X390SCA (Discontinued) -> MBL40X390SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 390mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X390SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X390SCA is a discontinued double-acting aluminum mini round cylinder engineered for a 40mm bore and 390mm stroke. Delivering 628N of push force at 0.5MPa, it utilizes a G1/4 port and a robust Ø16mm carbon-steel rod with 20um hard-chrome plating. AirTAC has replaced this legacy unit with the MBL40X390SCA, a drop-in alternative retaining the exact same force, porting, and CA pivot mounting.
This specific SKU features a built-in -S magnet and a CA pivot back cover designed to swing on a pin for arcing loads. The original MAL body relies on threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Furthermore, while the MAL -S magnet pairs with older CS1-M or DS1-M switches, upgrading to the MBL requires transitioning to current CMSG, DMSG, or EMSG sensors.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X390SCA 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.

Steers 30kg pallets along a sorting line using 628N of push force at 0.5MPa, with the CA pivot absorbing angular misalignment during the 390mm arc.
Pushes finished plastic parts out of a mold cavity, relying on the 16mm hard-chrome plated rod and self-lubricating bearing to handle repetitive 390mm extraction cycles.
Raises and lowers lightweight access gates in packaging machinery, using the 880N push force available at 0.7MPa to overcome initial static friction.
To replace the MAL40X390SCA, order the MBL40X390SCA, ensuring you match the 40mm bore, 390mm stroke, PT thread form, and CA pivot back cover. Because this SKU includes the -S magnet, note that your existing CS1-M or DS1-M switches will need to be swapped for CMSG, DMSG, or EMSG sensors on the new MBL. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this cylinder, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to a 32mm bore drops the push force to 402N at 0.5MPa, while no larger bore exists in this mini round series. Because the stroke is 390mm, the 16mm rod is susceptible to bending under lateral stress; always use the CA clevis to allow self-alignment or add an external guide to prevent side-load damage. Remember that the rubber bumper only softens end-of-stroke impacts and does not hold the load if air pressure is lost.
Upgrade checklist
Yes, the MAL40X390SCA is discontinued. The exact drop-in replacement is the MBL40X390SCA, which matches the 40mm bore, 390mm stroke, G1/4 port, and CA pivot mounting. You will need to update your sensors, as the older CS1-M and DS1-M switches are replaced by CMSG, DMSG, or EMSG models on the MBL.
At 0.5MPa, the push force is 628N and the pull force is 528N. At 0.7MPa, the push force increases to 880N. The maximum theoretical force is 128kgf at 1.0MPa. Operation is double-acting, with a speed range of 30-800mm/s.
