This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X20SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X20SU 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 MAL40X20SU (Discontinued) → MBL40X20SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 20mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X20SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X20SU is a discontinued double-acting aluminum mini round cylinder. It delivers 628 N push and 528 N pull at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard-chrome plating. The exact drop-in replacement is the MBL40X20SU, matching the 40 mm bore, 20 mm stroke, G1/4 port, and U flat-end back cover exactly. The legacy MAL features threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body for structural rigidity.
This SKU includes the -S magnet for position sensing. On the MAL, this magnet interfaces with the older CS1-M and DS1-M reed switches, but upgrading to the MBL requires migrating to the modern CMSG, DMSG, or EMSG sensor families. A heterogeneous two-way seal retains grease around the piston, while a self-lubricating bearing guide in the front cover reduces rod wear. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts, meaning it lacks adjustable air cushioning; if your application requires end-of-stroke deceleration tuning, you must step up to the MBLC variant on the current line.

| Max (@1.0 MPa) | 128 kgf | |
The MBL40X20SU 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.

Provides 628 N of push at 0.5 MPa to eject small plastic parts from tight mold cavities, utilizing the short 20 mm stroke for rapid cycling.
Actuates a diverter arm on a packaging conveyor, where the U flat-end cover provides rigid stability against lateral box impacts during routing.
Secures printed circuit boards during automated optical inspection, using the -S magnet and CS1-M/DS1-M switches to confirm clamp engagement.
To replace the MAL40X20SU, order the MBL40X20SU. Verify that your machine accepts the U flat-end back cover for rigid mounting and that your pneumatic lines match the G1/4 port. Because this SKU includes the -S magnet, you must account for a sensor family change: the legacy CS1-M and DS1-M switches will not fit the new body, so plan to purchase CMSG, DMSG, or EMSG sensors for the MBL. If your equipment requires adjustable air cushioning rather than a fixed rubber bumper, specify the MBLC40X20SU instead.
When sizing this cylinder, evaluate your force requirements carefully. If 628 N of push at 0.5 MPa is excessive for your payload, step down to the 32 mm bore, which provides 402 N of push force. Conversely, if you need substantially more power, there is no larger standard MAL mini-round bore, so you would transition to an ISO 15552 profile cylinder. Remember that a plain MAL or MBL does not hold its load when air pressure drops; the rod will drift. For vertical or gravity-loaded applications, install an external pilot-operated check valve or a dedicated rod lock.
Upgrade checklist
Yes, the MAL40X20SU is discontinued. The exact drop-in replacement is the MBL40X20SU, which matches the 40 mm bore, 20 mm stroke, G1/4 port, and U flat-end back cover. The MBL features a riveted rolling-packed body instead of the older threaded covers, and if your SKU has the -S magnet, you must upgrade from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG sensor family.
The 40 mm bore generates a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa.
