This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X520CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X520CA 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 MAL40X520CA (Discontinued) -> MBL40X520CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 520mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X520CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X520CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and a 520mm stroke. Because this stroke exceeds the 500mm standard maximum, it was produced as a non-standard, made-to-order item. It delivers a robust 628N push force at 0.5MPa using a G1/4 port and an M12x1.25 rod-end thread. AirTAC replaced this legacy unit with the MBL40X520CA, a drop-in alternative that matches the exact bore, stroke, output force, port size, and CA mounting configuration.
This specific SKU features a CA pivot back cover, allowing the cylinder to swing on a pin to absorb arcing loads. It lacks an -S magnet, meaning it cannot accommodate a position sensor. The original MAL body utilized threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Both generations rely on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion, though an MBLC variant offers adjustable air cushioning if precise deceleration is required.

The MBL40X520CA 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 traversing guide bar on a yarn spinning machine, utilizing the 628N push force and CA pivot to accommodate the slight arcing motion of the guide mechanism over its 520mm travel.
Stages corrugated cartons on a packaging conveyor line, where the 520mm stroke provides the necessary reach and the CA clevis absorbs lateral offset stresses during transfer.
Actuates a sorting diverter arm in a distribution center, relying on the robust 40mm bore to push heavy totes while the pivot mount prevents rod binding.
To replace the MAL40X520CA, order the MBL40X520CA and verify your CA pivot pin and G1/4 pneumatic fittings. Because this SKU lacks a magnet, you cannot mount a sensor; if position detection is needed, upgrade to an MBL40X520CAS and note that the modern MBL uses CMSG/DMSG/EMSG switches rather than the older CS1-M/DS1-M family. For sizing flexibility, stepping down to a 32mm bore yields 402N push at 0.5MPa, while stepping up to a 50mm bore (available in other AirTAC series) provides higher force. At 520mm, the 16mm rod is highly susceptible to bending under side loads; always use an external guide rail or ensure the CA clevis pivot moves freely to prevent premature seal failure. Remember that the rubber bumper only softens impact and does not lock the rod; if gravity or air-loss drift is a concern, install an external pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X520CA is discontinued. The exact drop-in replacement is the MBL40X520CA, which offers identical bore, stroke, force, G1/4 port, and CA pivot mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. It uses a G1/4 port, a 16mm rod, and an M12x1.25 rod-end thread.
