This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X620SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X620SU 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 MAL40X620SU (Discontinued) -> MBL40X620SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 620mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X620SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X620SU is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and a 620mm made-to-order stroke. It delivers 628 N of push force at 0.5 MPa and uses a G1/4 port with a 16mm carbon-steel rod. The exact drop-in replacement is the MBL40X620SU, which matches the bore, stroke, force, port, and flat-end U back cover. You simply order the MBL equivalent to keep your machine running.
This legacy SKU features a built-in -S magnet for position sensing. On the MAL, this magnet works with the older CS1-M and DS1-M reed switches, but the MBL replacement upgrades you to the current CMSG, DMSG, or EMSG sensor families. The original MAL body uses threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for equally robust performance. Both generations rely on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

The MBL40X620SU 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 reliably kick folded cardboard blanks into the forming station on high-speed packaging lines.
The 620mm made-to-order stroke provides the long linear travel needed to open and close safety access gates on large CNC router beds.
Leverages the G1/4 port and 16mm hard-chrome rod to swing heavy pallets onto a secondary conveyor track in distribution hubs.
To replace the MAL40X620SU, order the MBL40X620SU. Confirm your 40mm bore, 620mm non-standard stroke, G1/4 port, and the U flat-end back cover. Because this SKU includes the -S magnet, plan to upgrade your old CS1-M or DS1-M sensors to the modern CMSG, DMSG, or EMSG switches used on the MBL. If your application needs an adjustable air cushion rather than a fixed rubber bumper, step up to the current MBLC series.
With a 620mm stroke, the 16mm rod is highly susceptible to bending under side loads; you must use an external guide or a pivot mount to prevent premature seal wear. If you need to adjust sizing, stepping down to the 32mm bore yields 402 N of push force at 0.5 MPa, while stepping up is not an option as 40mm is the largest mini-round bore available. Remember that a plain MAL or MBL does not hold a load when air pressure is lost, so install an external rod lock for vertical safety.
Upgrade checklist
Yes, the MAL40X620SU is discontinued. The exact drop-in replacement is the MBL40X620SU, which matches the 40mm bore, 620mm stroke, G1/4 port, U flat-end back cover, and 628 N push force. You can order the MBL40X620SU as a direct fit, though you will need to upgrade any old CS1-M or DS1-M sensors to the modern CMSG, DMSG, or EMSG switch family.
The MAL40X620SU operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s. At 0.5 MPa it provides 628 N of push force and 528 N of pull force. At 0.7 MPa the push force is 880 N, and the theoretical maximum force is 128 kgf at 1.0 MPa.
