This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X900-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X900-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 MAL40X900-S-U (Discontinued) → MBL40X900-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 900mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X900-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X900-S-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 900mm stroke. Because 900mm exceeds the 500mm standard limit, this is a non-standard, made-to-order stroke. It delivers 628N push and 528N pull at 0.5MPa, rising to 880N at 0.7MPa. The exact drop-in replacement is the MBL40X900-S-U, matching the force, G1/4 port, and U flat-end rear cover.
This legacy SKU features a built-in -S magnet for position detection via CS1-M or DS1-M switches; upgrading to the MBL40X900-S-U shifts you to the modern CMSG, DMSG, or EMSG sensor family. The original MAL body uses threaded front and back covers, whereas the MBL utilizes a riveted rolling-packed construction. A fixed rubber bumper absorbs end-of-stroke impact, but it is not an adjustable cushion or a position lock.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X900-S-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 MBL40X900-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.

Uses the 628N push force at 0.5MPa to index heavy pallets along a 900mm roller conveyor in packaging lines.
Extends a machine tool safety door across the full 900mm travel, relying on the U flat-end cover for rigid, non-arcing mounting.
Lifts stacked metal trays in a storage module, requiring an external guide to support the load over the 900mm extension.
To replace the MAL40X900-S-U, order the MBL40X900-S-U and verify your 40mm bore, 900mm stroke, G1/4 port, and PT thread form. You must also migrate your position sensing: the older CS1-M and DS1-M switches will not fit the MBL, so select current CMSG, DMSG, or EMSG sensors. If your application requires adjustable end-cushioning to tame the 16mm rod over 900mm, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up is not an option as 40mm is the largest MAL/MBL mini round bore. Because this is a 900mm stroke, the 16mm carbon-steel rod is highly susceptible to bending under side-loads; always use an external guide rail or a pivot mount. Note that a plain cylinder drifts when air is lost, so add an external rod lock or pilot-operated check valve if the load must be held.
Upgrade checklist
Yes, the MAL40X900-S-U is discontinued. The exact drop-in replacement is the MBL40X900-S-U, which matches the 40mm bore, 900mm stroke, G1/4 port, and U flat-end rear cover. The MBL uses a riveted rolling-packed body instead of threaded covers, and its -S magnet requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches.
At 0.5MPa it provides 628N push and 528N pull, increasing to 880N push at 0.7MPa, with a theoretical maximum of 128kgf at 1.0MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption, not an adjustable cushion. If adjustable cushioning is needed, the current-line MBLC variant offers that feature.
