This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X550-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X550-CA 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 MAL40X550-CA (Discontinued) → MBL40X550-CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 550mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X550-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X550-CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 550mm stroke. Because 550mm exceeds the 500mm standard maximum, this unit was a made-to-order configuration. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a robust Ø16mm carbon-steel rod with 20µm hard chrome plating. The CA back cover is a pivot clevis that swings on a pin to accommodate arcing motions.
AirTAC replaced this legacy unit with the MBL40X550-CA, a drop-in alternative retaining the exact same 40mm bore, 550mm stroke, 128kgf maximum force, G1/4 port, and CA mounting. The original MAL features threaded front and back covers, whereas the upgraded MBL uses a riveted rolling-packed body. Note that this specific SKU lacks an -S magnet, meaning it cannot accept a position sensor; if you ever relied on CS1-M or DS1-M switches on other MAL units, the MBL replacement requires the modern CMSG, DMSG, or EMSG family.

The MBL40X550-CA 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.

Drives the oscillating beater bar on a weaving loom, using the 628N push force at 0.5MPa to pack weft threads while the CA clevis absorbs the lateral arc.
Ejects heavy wooden pallets from a machining cell, relying on the 880N push force at 0.7MPa and the 550mm stroke to clear the workstation entirely.
Pushes steel hinge blanks into a robotic welding fixture, utilizing the 16mm hard-chrome rod to resist minor abrasive contact during the 550mm extension.
To replace the MAL40X550-CA, order the MBL40X550-CA to guarantee identical G1/4 ports, M12x1.25 rod-end threads, and CA pivot mounting. Since this 550mm stroke exceeds the 500mm standard limit, expect a non-standard production lead time. For sizing flexibility, stepping down to the 32mm bore yields 402N push force at 0.5MPa, while stepping up to larger ISO profile cylinders provides higher force if this 880N push at 0.7MPa is insufficient. At 550mm, the 16mm rod is highly susceptible to bending under side loads; always use the CA clevis to absorb angular misalignment or add an external guide rail. The fixed rubber bumper softens end-of-stroke impacts but does not lock the rod—if air pressure drops, the load will drift, requiring an external pilot-operated check valve for position holding. If adjustable cushioning is required for this long stroke, upgrade to the current MBLC series.
Upgrade checklist
Yes, the MAL40X550-CA is discontinued. The exact drop-in replacement is the MBL40X550-CA, which matches the 40mm bore, 550mm stroke, 128kgf max force, G1/4 port, and CA pivot mounting. The newer MBL features a riveted rolling-packed body instead of the older threaded covers.
At 0.5MPa, the 40mm bore provides 628N push and 528N pull force. At 0.7MPa, push force is 880N, with a theoretical maximum of 128kgf at 1.0MPa. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor like the older CS1-M or DS1-M switches.
