This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X225-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X225-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 MAL40X225-S-U (Discontinued) → MBL40X225-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 225mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X225-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X225-S-U is a discontinued double-acting aluminum mini round cylinder with a 40 mm bore and 225 mm stroke. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL40X225-S-U, which matches the original bore, stroke, output force, G1/4 porting, and flat-end U back cover.
This legacy unit features a built-in -S magnet designed for the older CS1-M and DS1-M reed switches, whereas the modern MBL replacement utilizes the current CMSG, DMSG, or EMSG sensor families. The original MAL body relies on threaded front and back covers, while the updated MBL uses a riveted rolling-packed body for structural rigidity. Both generations share a fixed rubber bumper to soften end-of-stroke impacts, though neither provides adjustable air cushioning—that feature is exclusive to the MBLC variant on the current line.

| Max (@1.0 MPa) | 128 kgf | |
The MBL40X225-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 628 N push force at 0.5 MPa to swing a diverting arm on a packaging conveyor, with the 225 mm stroke providing the full reach needed to redirect heavy cardboard cartons.
Secures aluminum engine blocks during machining operations, relying on the rigid U flat-end back cover to maintain alignment under the 880 N thrust available at 0.7 MPa.
Pushes filled product boxes out of a filling station, where the -S magnet and CS1-M sensor confirm the full 225 mm extension before the conveyor advances.
To replace this MAL40X225-S-U, order the MBL40X225-S-U to retain the exact 40 mm bore, 225 mm stroke, G1/4 port, PT thread form, and U flat-end back cover. Because this SKU includes the -S magnet, note that your existing CS1-M or DS1-M switches will need to be upgraded to CMSG, DMSG, or EMSG sensors to fit the MBL body. If your application requires adjustable air cushioning rather than the fixed rubber bumper, step up to the MBLC40X225-S-U.
For sizing flexibility, stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up is not an option as 40 mm is the largest standard MAL mini round bore. At 225 mm of stroke, the 16 mm carbon-steel rod with 20 um hard-chrome plating has limited side-load tolerance; use an external guide rail or a pivot mounting accessory to prevent rod bending. Remember that the bumper only absorbs shock and does not hold the load—if air pressure is lost, the rod will drift, requiring an external rod lock for position holding.
Upgrade checklist
Yes, the MAL40X225-S-U is discontinued. The exact drop-in replacement is the MBL40X225-S-U, which provides identical 40 mm bore, 225 mm stroke, 628 N push force, G1/4 port, and U flat-end mounting. You must upgrade your sensors, as the MAL -S magnet uses older CS1-M or DS1-M switches, while the MBL requires CMSG, DMSG, or EMSG switches.
At 0.5 MPa, the 40 mm bore provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at the 1.0 MPa operating pressure limit.
