This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X450-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X450-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 MAL40X450-CM (Discontinued) -> MBL40X450-CM 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-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X450-CM is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 450mm stroke. It delivers a robust 628N push force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. As a legacy component, its exact drop-in replacement is the MBL40X450-CM, which matches the original bore, stroke, output force, port size, and mounting interface perfectly.
This specific SKU features a CM round-end back cover and lacks a built-in magnet, meaning it cannot support any position sensing. The original MAL body used threaded front and back covers on the barrel, whereas the modern MBL replacement upgrades to a riveted rolling-packed body construction. Both designs employ a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X450-CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X450-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.

Uses the 628N push force at 0.5MPa to positively eject heavy plastic moldings from the cavity without damaging the parting line.
Leverages the 450mm stroke and CM round-end cover to swing a diverter arm across a conveyor lane for routing heavy packaged goods.
Actuates a 450mm lifting stroke on a compact storage gate, relying on the 16mm hard-chrome rod to handle the dynamic load.
To replace the MAL40X450-CM, order the MBL40X450-CM and verify your setup accommodates the G1/4 port and PT tapered thread form. The CM round-end back cover must be paired with the appropriate clevis or rod-end knuckle to handle arcing movements. Because this is a non-magnetized model, you cannot mount a sensor; if position detection is required, you must upgrade to an MBL40X450-S-CM and switch from the legacy CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG family.
For sizing flexibility, stepping down to the 32mm bore yields 402N of push force at 0.5MPa, while stepping up to the 50mm profile cylinder provides significantly higher thrust. At 450mm of stroke, the 16mm carbon-steel rod is highly susceptible to bending under side loads; always use an external guide rail or a pivot mount to prevent premature seal wear. If your application requires precise end-of-stroke deceleration rather than a fixed rubber bumper, specify the MBLC variant for its adjustable air cushion. Remember that a plain cylinder drifts when air is lost, so add an external rod lock for fail-safe load holding.
Upgrade checklist
Yes, the MAL40X450-CM is discontinued. The exact drop-in replacement is the MBL40X450-CM, which matches the 40mm bore, 450mm stroke, 628N push force at 0.5MPa, G1/4 port, and CM round-end mounting. The MBL upgrades the body to a riveted rolling-packed design while retaining the same footprint.
The bore delivers 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 option, it cannot support any position sensors; legacy MAL sensors required the -S option, and the modern MBL replacement uses the CMSG/DMSG/EMSG switch family.
