This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X425SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X425SCA 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 MAL40X425SCA (Discontinued) → MBL40X425SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 425mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X425SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X425SCA is a discontinued double-acting aluminum mini round cylinder. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The exact drop-in replacement is the MBL40X425SCA, matching the 40 mm bore, 425 mm stroke, G1/4 port, and CA pivot mounting. The legacy MAL uses a threaded front and back cover assembly, whereas the modern MBL features a riveted rolling-packed body for equal structural integrity.
This specific SKU includes a built-in magnet (-S) and a CA pivot clevis back cover. Because of the -S magnet, the original cylinder pairs with older CS1-M or DS1-M reed switches; upgrading to the MBL requires migrating to the current CMSG, DMSG, or EMSG sensor family. The 16 mm carbon-steel rod has a 20 um hard-chrome plating and rides on a self-lubricating front-cover bearing guide with a heterogeneous two-way grease-retaining seal.

The MBL40X425SCA 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 425 mm of travel to eject deep-cavity plastic parts from injection molding machines, utilizing the 628 N push force to overcome mold friction.
Actuates a sweeping arm on a packaging conveyor, where the CA pivot clevis accommodates the arcing sweep motion without stressing the 16 mm rod.
Raises and lowers a 40 mm bore lift mechanism for heavy tote boxes, requiring the full 880 N push force at 0.7 MPa to overcome gravity.
To replace the MAL40X425SCA, order the MBL40X425SCA. Verify your 425 mm stroke, G1/4 port, PT thread form, and the CA pivot back cover. If your application requires an adjustable air cushion rather than the standard fixed rubber bumper, step up to the MBLC40 series on the current line. If you need to hold a load vertically during a pressure loss, note that neither the MAL nor the MBL bumper acts as a lock—you must add an external rod lock or pilot-operated check valve.
At 425 mm of travel, the 16 mm rod is highly susceptible to bending under lateral stress; the CA pivot clevis is essential here to absorb arcing loads and prevent rod binding. For sizing flexibility, stepping down to a 32 mm bore yields 402 N of push force at 0.5 MPa, while no larger standard mini-round bore exists in this family. The MAL40X425SCA provides a maximum theoretical output of 128 kgf at 1.0 MPa.
Upgrade checklist
Yes, the MAL40X425SCA is discontinued. The exact drop-in replacement is the MBL40X425SCA, which retains the same 40 mm bore, 425 mm stroke, G1/4 port, and CA pivot mounting. The main change is that your existing CS1-M or DS1-M sensors will need to be replaced with CMSG, DMSG, or EMSG switches to fit the MBL body.
The 40 mm bore provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf when operated at the 1.0 MPa pressure limit.
