This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X145SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X145SU 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 MAL40X145SU (Discontinued) → MBL40X145SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 145mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X145SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X145SU is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 145mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, making it the highest output class in the MAL family. AirTAC replaced this legacy unit with the MBL40X145SU, a drop-in alternative retaining the exact 16mm rod, M12x1.25 thread, G1/4 port, and U flat-end rear cover.
This SKU includes a built-in magnet for position sensing. The older MAL body uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed assembly. If you relied on CS1-M or DS1-M switches on this MAL, you must upgrade to CMSG, DMSG, or EMSG sensors for the MBL replacement. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20um hard-chrome plating to resist wear in dry environments.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X145SU 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 MBL40X145SU 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.

Drives folding mechanisms on packaging lines where 628N of push force at 0.5MPa firmly closes heavy cardboard flaps before taping.
Presses small bronze bushings into aluminum housings on an assembly jig, using the 145mm stroke to clear the tooling during part loading.
Acts as a pneumatic stop on a roller conveyor, holding back pallets weighing up to 128kgf using the rigid U flat-end rear cover.
To replace the MAL40X145SU, order the MBL40X145SU and verify your G1/4 porting, PT threads, and U flat-end back cover clearances. Because this SKU has the -S magnet, remember that CS1-M and DS1-M reed switches are retired; migrate to CMSG, DMSG, or EMSG electronic sensors on the MBL. The MAL relies on a fixed rubber bumper for end-of-stroke damping. If your application requires adjustable air cushioning to prevent shock at high speeds, step up to the current MBLC40 variant.
For sizing flexibility, you can step down to a 32mm bore if 563N of push at 0.7MPa is sufficient, or look beyond the family for larger profile cylinders if you need more than the 880N this 40mm bore provides at 0.7MPa. Note that a plain MAL or MBL does not hold its position when air pressure drops; the rod will drift. Use an external rod lock or pilot-operated check valve if the load must remain suspended during an air failure.
Upgrade checklist
Yes, the MAL40X145SU is discontinued. The exact drop-in replacement is the MBL40X145SU, which matches the 40mm bore, 145mm stroke, 628N push force, G1/4 port, and U flat-end mounting. You only need to update your position sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family.
The 40mm 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. It uses a fixed rubber bumper, not an adjustable cushion, and operates at speeds of 30-800mm/s.
