This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X275SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X275SCA 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 MAL40X275SCA (Discontinued) → MBL40X275SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 275mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X275SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X275SCA is a discontinued double-acting aluminum mini round cylinder engineered for compact automation. Delivering 628 N of push force at 0.5 MPa, it features a 40 mm bore, a 275 mm stroke, and a CA pivot back cover. AirTAC replaced this legacy unit with the MBL40X275SCA, a drop-in alternative retaining the exact same bore, stroke, output force, G1/4 port, and CA mounting interface.
This SKU includes a built-in magnet (-S) for position detection. Because the original MAL body used threaded front and back covers, it structurally differs from the riveted rolling-packed body of the modern MBL. Furthermore, the -S magnet on this discontinued cylinder interfaces only with legacy CS1-M or DS1-M reed switches, whereas the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families.

The MBL40X275SCA 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 a sliding safety door on a CNC lathe, utilizing the 880 N push force at 0.7 MPa to reliably overcome guide resistance and move the 275 mm stroke.
Swings a diverter arm on a packaging conveyor via the CA pivot back cover, using the 628 N force to push heavy cardboard cartons onto a secondary lane.
Ejects filled product cases from a palletizer station, depending on the 128 kgf maximum theoretical force to overcome box weight friction over the 275 mm travel.
To replace the MAL40X275SCA, order the MBL40X275SCA and verify your CA pivot pin and G1/4 pneumatic fittings. The 275 mm stroke on a 16 mm rod demands careful alignment; for strokes of 300 mm or more, side-load tolerance drops significantly, requiring an external guide rail or a pivot mount to prevent rod bending. If you need to step down, the 32 mm bore neighbor provides 402 N push at 0.5 MPa; stepping up is not an option as 40 mm is the largest available MAL mini round body. Note that the fixed rubber bumper cannot hold this load if air pressure drops, so add a pilot-operated check valve for position holding. If end-of-stroke impact is too harsh, upgrade to the current MBLC which offers an adjustable air cushion.
Upgrade checklist
Yes, the MAL40X275SCA is discontinued. The exact drop-in replacement is the MBL40X275SCA, which matches the 40 mm bore, 275 mm stroke, CA pivot cover, and G1/4 port. You must update your sensor inventory, as the MAL -S magnet uses legacy CS1-M/DS1-M switches while the MBL uses CMSG/DMSG/EMSG sensors.
The 40 mm bore uses a 16 mm carbon-steel rod with an M12x1.25 end thread. At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it provides 880 N push. The maximum theoretical force is 128 kgf at 1.0 MPa.
