This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X400ULB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X400ULB 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 MAL40X400ULB (Discontinued) -> MBL40X400ULB 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 MBL40X400ULB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X400ULB is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 400mm stroke. 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 exact drop-in replacement is the MBL40X400ULB, matching the bore, stroke, output force, port size, and LB mounting footprint exactly.
This legacy SKU includes a U flat-end back cover for rigid rear mounting and an LB foot bracket accessory. Because this specific model lacks the -S magnet option, it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the current MBL upgrade features a riveted rolling-packed body for enhanced structural integrity.

The MBL40X400ULB 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 deflect packaged goods off a flat belt conveyor into a sorting chute at the end of a packaging line.
Employs the 400mm stroke to fully retract a heavy safety enclosure door, relying on the LB foot mount to stabilize the 16mm rod against vertical sag.
Drives a 400mm vertical material lift gate on a storage carousel, where the U flat-end back cover provides a rigid, non-articulating rear anchor point.
To replace the MAL40X400ULB, order the MBL40X400ULB and verify your 40mm bore, 400mm stroke, G1/4 port, and LB foot mounting holes align. The default PT tapered port thread remains unchanged. If your application requires position sensing, note that this specific no-magnet SKU cannot support a sensor; you would need to specify an -S magnet on the MBL, which upgrades the switch family from the legacy CS1-M/DS1-M to the modern CMSG/DMSG/EMSG sensors.
For sizing flexibility, stepping down to the 32mm bore neighbor yields 402 N push at 0.5 MPa, while stepping up is not an option as 40mm is the largest in this mini series. At 400mm of stroke, the 16mm rod is highly susceptible to bending under side loads; use an external guide rail or a pivot mount to prevent premature seal wear. The fixed rubber bumper softens end-of-stroke impacts but does not lock the load—if air pressure drops, the rod will drift, requiring an external rod lock for safety. If adjustable end-cushioning is needed for heavy moving masses, step up to the MBLC variant on the current line.
Upgrade checklist
Yes, the MAL40X400ULB is discontinued. The exact drop-in replacement is the MBL40X400ULB, which matches the 40mm bore, 400mm stroke, 628 N push force, G1/4 port, and LB foot mount. The MBL upgrades the body from threaded covers to a riveted rolling-packed construction.
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, with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor.
