This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X40SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X40SU 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 MAL40X40SU (Discontinued) → MBL40X40SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 40mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X40SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X40SU is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 40mm stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X40SU, which matches the bore, stroke, output force, port size, and mounting accessories perfectly.
This legacy SKU features a built-in magnet (-S) for position detection, originally designed for the older CS1-M and DS1-M switches. When upgrading to the MBL40X40SU, you must update your sensors to the current CMSG, DMSG, or EMSG families. Additionally, the older MAL body uses threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body construction for enhanced durability. The U designation indicates a flat-end back cover, providing a rigid rear mount for straightforward inline installations.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X40SU 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 628N of push force at 0.5 MPa to eject small plastic parts from injection molds, utilizing the 40mm stroke for rapid retraction in tight machine cavities.
Actuates a diverter arm on a high-speed packaging conveyor, where the flat-end U cover ensures rigid rear mounting and the -S magnet confirms stroke completion.
Folds corrugated carton flaps during case erecting, relying on the self-lubricating front-cover bearing guide to maintain smooth operation over thousands of cycles.
To replace the MAL40X40SU, order the MBL40X40SU and verify your setup: confirm the 40mm bore, 40mm stroke, G1/4 port, PT thread form, flat-end U back cover, and the -S magnet requirement. Because this unit has a magnet, remember the MBL replacement mandates a sensor swap to CMSG, DMSG, or EMSG switches. If you need to adjust your force output, stepping down to the 32mm bore yields 402N push at 0.5 MPa, while stepping up to the 50mm profile cylinder provides significantly higher thrust. The 40mm stroke keeps side-load risk minimal, but the 16mm carbon-steel rod with 20um hard-chrome plating still requires an external guide if subjected to lateral loads. For applications needing end-of-stroke deceleration, remember the MAL uses a fixed rubber bumper; you must step up to the MBLC line for an adjustable air cushion. Finally, this cylinder will not hold a load if air pressure drops, so install an external rod lock for vertical or gravity-loaded tasks.
Upgrade checklist
Yes, the MAL40X40SU is discontinued. The exact drop-in replacement is the MBL40X40SU, which matches the 40mm bore, 40mm stroke, 628N force, G1/4 port, and U flat-end mounting. The MBL body uses a riveted rolling-packed design instead of threaded covers, and if your unit has a -S magnet, you must upgrade from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG sensor family.
The MAL40X40SU delivers a push force of 628N and a pull force of 528N at 0.5 MPa. At 0.7 MPa, the push force is 880N, with a maximum theoretical force of 128kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s within an operating pressure range of 0.1-1.0 MPa.
