This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X180U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X180U 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 MAL40X180U (Discontinued) → MBL40X180U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 180mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X180U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X180U is a discontinued 40mm bore, 180mm stroke double-acting aluminum mini round cylinder. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The U designation indicates a flat-end back cover for rigid, fixed mounting. Because this legacy series is end-of-life, you should order the exact drop-in replacement: the MBL40X180U. It matches the bore, stroke, output force, port size, and mounting accessories perfectly.
This SKU lacks a built-in magnet, meaning it cannot accept a position sensor. A key upgrade detail is that the MAL uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. The piston relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide. The carbon-steel rod has 20 um hard chrome plating to resist wear. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X180U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X180U 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.

Actuates a diverting gate on a packaging conveyor, using the 628 N push force at 0.5 MPa to reliably redirect 15kg cardboard cartons onto a secondary belt line.
Pushes 40mm aluminum bar stock into a lathe spindle, relying on the rigid U flat-end back cover to maintain precise axial alignment during the 180mm feed cycle.
Drives an external ejection arm to knock plastic parts off an injection mold tool, where the fixed rubber bumper safely absorbs the end-of-stroke impact without marking the parts.
To replace the MAL40X180U, order the MBL40X180U. Confirm the 40mm bore, 180mm stroke, G1/4 port, PT tapered thread, and the U flat-end back cover. Because this model has no -S magnet, it cannot support a sensor; if you need position detection, you must step up to an MBL40X180US and upgrade to the modern CMSG, DMSG, or EMSG switch family (the older CS1-M/DS1-M sensors are obsolete). If you need adjustable end-cushioning to handle the kinetic energy of this bore, step up to the current MBLC line, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, you can step down to the 32mm bore (402 N push at 0.5 MPa) if your load is lighter, or step up to the largest mini round bore available. At 180mm stroke, the 16mm rod is susceptible to bending under side loads; use a CA pivot back cover, an SDB pivot bracket, or an external guide rail to prevent rod damage. Note that a plain MBL does not hold its load when air is lost—the rod will drift—so install an external rod lock or pilot-operated check valve for fail-safe holding.
Upgrade checklist
Yes, the MAL40X180U is discontinued. The exact drop-in replacement is the MBL40X180U. It shares the same 40mm bore, 180mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and U flat-end mounting. The main physical difference is the MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N, and the maximum theoretical force is 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; you would need an -S variant and the modern CMSG/DMSG/EMSG switches for detection.
