This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X300-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X300-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 MAL40X300-U (Discontinued) -> MBL40X300-U 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-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 300mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and a rigid U flat-end back cover. AirTAC replaced this legacy unit with the MBL40X300-U, a drop-in alternative that matches the exact bore, stroke, output force, port size, and mounting interface.
This SKU lacks a built-in magnet, so it cannot support position sensing without external modifications. The original MAL features threaded front and back covers, whereas the current MBL replacement uses a riveted rolling-packed body for structural rigidity. Additionally, the MAL relies on a fixed rubber bumper to soften end-of-stroke impacts; if your application requires adjustable air cushioning, you must step up to the current MBLC line, as the MAL never offered this feature.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X300-U 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 MBL40X300-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.

Uses the 628N push force at 0.5MPa to deflect heavy packaging pallets on a sorting line, with the 300mm stroke providing full lane separation.
Moves a sliding safety enclosure on a machine tool, relying on the rigid U flat-end back cover to maintain axial alignment across the 300mm travel.
Ejects filled cardboard cartons from a filling station, where the fixed rubber bumper absorbs the repeated impact of the 40mm bore reaching end of stroke.
To replace the MAL40X300-U, order the MBL40X300-U. Confirm the 40mm bore, 300mm stroke, G1/4 port, and the default PT tapered thread form are retained. The U flat-end back cover provides rigid axial mounting, but because this unit lacks the -S magnet, it cannot accept CS1-M or DS1-M sensors. If you need position detection on the new unit, add an S to the MBL order code, which will require the current CMSG, DMSG, or EMSG switch family.
For sizing flexibility, stepping down to a 32mm bore drops the 0.5MPa push force to 402N, while stepping up is not an option as 40mm is the largest MAL/MBL mini round bore available. Because this 300mm stroke is relatively long for a 16mm rod, side-load tolerance is low; use an external guide rail or a pivot mounting accessory to prevent rod bending. Remember that neither the MAL nor the MBL holds its position when air pressure is lost, so install an external rod lock for vertical loads.
Upgrade checklist
Yes, the MAL40X300-U is discontinued. The exact drop-in replacement is the MBL40X300-U, which provides identical bore, stroke, force, G1/4 port, and U flat-end mounting. The main physical change is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The 40mm bore operates on a G1/4 port. At 0.5MPa it provides 628N of push force and 528N of pull force. At 0.7MPa the push force is 880N, and the maximum theoretical force is 128kgf at 1.0MPa.
