This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X280U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X280U 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 MAL40X280U (Discontinued) -> MBL40X280U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 280mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X280U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X280U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 280mm stroke. Delivering 628N of push force and 528N of pull force at 0.5MPa, it utilizes a G1/4 port and a rigid U flat-end back cover. The exact drop-in replacement is the MBL40X280U, which matches the original bore, stroke, output force, port size, and mounting dimensions perfectly.
This legacy unit features threaded front and back covers, whereas the modern MBL40X280U upgrade utilizes a riveted rolling-packed body for enhanced structural integrity. The MAL40X280U SKU lacks a built-in magnet, meaning it cannot support any position sensing. Additionally, it relies on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion, a feature only available on the current MBLC line.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X280U 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.

Acts as a pneumatic stop gate in end-of-line pallet conveyors, using 628N of thrust at 0.5MPa to halt heavy 40x120cm Euro pallets before the wrapping station.
Drives a mechanical arm to fold major flaps on large corrugated shipping cartons, where the 280mm stroke provides the reach needed to clear tall box profiles.
Ejects lightweight aluminum die-cast parts from a small press bed, utilizing the 16mm hard-chrome plated rod to push parts clear of the lower die.
To replace the MAL40X280U, order the MBL40X280U and verify your 40mm bore, 280mm stroke, G1/4 port, and default PT tapered thread. Confirm the U flat-end back cover is appropriate for your rigid mounting setup. Since this SKU lacks an -S magnet, no position sensor can be installed; if you need end-of-stroke detection, you must upgrade to an MBL40X280US and switch to the modern CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are obsolete. If you need adjustable end-cushioning to dissipate kinetic energy, step up to the MBLC40X280U.
For sizing flexibility, stepping down to the 32mm bore yields 402N of push force at 0.5MPa, while stepping up is not an option as 40mm is the largest MAL/MBL mini round bore. Because the stroke is 280mm, the 16mm carbon-steel rod is susceptible to bending under side-loads; use an external guide rail, a pivot mount, or a double-rod MBLD40X280U to prevent premature seal wear. Remember that a plain MBL cylinder does not hold its position or load when air pressure is lost, as the rubber bumper only softens impact and does not act as a rod lock.
Upgrade checklist
Yes, the MAL40X280U is discontinued. The exact drop-in replacement is the MBL40X280U, offering the same 40mm bore, 280mm stroke, 628N push force at 0.5MPa, G1/4 port, and U flat-end mounting. The MBL uses a riveted rolling-packed body instead of the old threaded covers, but requires no machine modifications.
At 0.5MPa, the push force is 628N and the pull force is 528N. At 0.7MPa, the push force reaches 880N. The maximum theoretical force is 128kgf at 1.0MPa. Note that this specific SKU has no magnet, so position sensing is not possible.
