This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X400-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X400-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 MAL40X400-S-U (Discontinued) → MBL40X400-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 400mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X400-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X400-S-U is a discontinued double-acting aluminum mini round cylinder, delivering a robust 628 N push force at 0.5 MPa. Featuring a 40 mm bore and 400 mm stroke, it utilizes a G1/4 port and a Ø16 mm carbon-steel rod with 20 um hard chrome plating. The U suffix denotes a rigid flat-end back cover, while the -S indicates a built-in magnet for position sensing. AirTAC replaced this legacy unit with the MBL40X400-S-U, a drop-in alternative retaining the exact bore, stroke, output force, port size, and mounting interface.
When upgrading to the MBL40X400-S-U, note that the original MAL threaded front and back covers are replaced by a riveted rolling-packed body for structural rigidity. Furthermore, the -S magnet on this legacy cylinder interfaces with older CS1-M or DS1-M reed switches, whereas the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The MAL relies on a fixed rubber bumper for end-of-stroke deceleration; if your application requires adjustable pneumatic cushioning, you must step up to the current-line MBLC variant.

The MBL40X400-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 positively eject heavy wooden pallets from a transfer line, relying on the 400 mm stroke to clear the conveyor width entirely.
Drives a heavy sliding machine tool door over the 400 mm travel, where the rigid U flat-end back cover maintains alignment and the fixed rubber bumper prevents slamming at high cycle speeds.
Folds large corrugated carton flaps on a continuous packaging conveyor, utilizing the 880 N push force at 0.7 MPa to overcome cardboard spring-back in tight machinery spaces.
To replace the MAL40X400-S-U, order the MBL40X400-S-U and verify your setup accommodates the G1/4 port, M12x1.25 rod-end thread, and rigid U flat-end back cover. Because this SKU includes the -S magnet, plan to replace any existing CS1-M or DS1-M sensors with CMSG, DMSG, or EMSG switches to match the MBL's updated magnetic profile. If you need to adjust force, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while no larger mini round body exists in this range. Note that a plain MBL does not hold its position or load when air is lost, as the bumper only softens the stroke end and is not a lock; utilize an external rod lock for suspended loads.
With a 400 mm stroke on a 16 mm rod, this cylinder has low side-load tolerance and is highly susceptible to rod bending. You must support the load with an external guide rail or use a pivot mounting accessory to absorb any arcing motion. The self-lubricating front-cover bearing guide and heterogeneous two-way grease-retaining seal help manage friction, but they cannot compensate for severe misalignment over a long stroke.
Upgrade checklist
Yes, the AirTAC MAL40X400-S-U is discontinued. The exact drop-in replacement is the MBL40X400-S-U, which matches the 40 mm bore, 400 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and U flat-end mounting. You must update your sensors, as the older CS1-M/DS1-M switches are replaced by CMSG/DMSG/EMSG on the MBL.
The MAL40X400-S-U delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a G1/4 port, a 16 mm rod, and operates at 30-800 mm/s with a fixed rubber bumper.
