This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X450-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X450-S-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 MAL40X450-S-U (Discontinued) -> MBL40X450-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 450mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X450-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X450-S-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 450mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. AirTAC replaced this legacy unit with the MBL40X450-S-U, a drop-in alternative retaining the exact same bore, stroke, output force, port size, flat-end rear cover, and mounting accessories.
This specific SKU includes a built-in magnet (-S) for position detection; the legacy MAL uses older CS1-M or DS1-M switches, whereas the current MBL replacement requires CMSG, DMSG, or EMSG sensors. A key structural upgrade is the body construction: the old MAL used threaded front and back covers, while the modern MBL features a riveted rolling-packed body for enhanced integrity. Both generations rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion, though the current line offers an MBLC variant if adjustable cushioning is required.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X450-S-U 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 MBL40X450-S-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 heavy pallets off a packaging conveyor using 628N of thrust at 0.5MPa, with the 450mm stroke providing the reach needed to clear the belt.
Actuates a routing machine gate where the -S magnet and CS1-M/DS1-M switch confirm the door is fully open before the spindle starts.
Folds heavy cardboard carton flaps prior to sealing, relying on the flat-end U rear cover for rigid mounting against the machine frame.
To replace the MAL40X450-S-U, order the MBL40X450-S-U and verify your setup accommodates the newer CMSG/DMSG/EMSG sensor family instead of the older CS1-M/DS1-M switches. Confirm the G1/4 port and M12x1.25 rod thread match your existing fittings. If 628N push at 0.5MPa is excessive, step down to the 32mm bore (402N push); if you need more power, note this 40mm bore is the largest available in this mini series. Because this is a 450mm stroke, the 16mm carbon-steel rod with 20um hard chrome plating is highly susceptible to bending under side loads—use an external guide rail or a pivot mount to prevent premature seal wear.
Remember that the fixed rubber bumper softens impact but does not lock the rod; a plain MBL will drift and drop its load when air pressure is lost. For position holding, install an external pilot-operated check valve. If your application demands precise end-of-stroke deceleration rather than a rubber bumper, upgrade to the MBLC variant on the current line for adjustable air cushioning.
Upgrade checklist
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL40X450-S-U, which matches the 40mm bore, 450mm stroke, 628N force, G1/4 port, and flat-end cover. Note that the -S magnet on the new MBL uses CMSG, DMSG, or EMSG sensors instead of the older CS1-M/DS1-M switches.
At 0.5MPa, it provides 628N push and 528N pull force. At 0.7MPa, the push force is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. The operating speed ranges from 30-800mm/s.
