AirTAC has phased out the MAL series. The drop-in replacement is MBL40X125-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X125-S-CM 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 MAL40X125-S-CM (Discontinued) → MBL40X125-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 125mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X125-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X125-S-CM is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 125mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. This specific SKU includes a built-in magnet (-S) for position sensing and a CM round-end back cover. The exact drop-in replacement is the MBL40X125-S-CM, matching the bore, stroke, force, port, and mounting.
When upgrading to the MBL40X125-S-CM, note two structural changes. The legacy MAL uses threaded front and back covers on the barrel, whereas the MBL features a riveted rolling-packed body. Additionally, the -S magnet on this MAL works with the older CS1-M and DS1-M switches; the MBL replacement requires the current CMSG, DMSG, or EMSG sensor family. The MAL relies on a fixed rubber bumper for end-of-stroke damping, while the current line offers an adjustable air cushion via the MBLC variant. The piston uses a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide.

The MBL40X125-S-CM 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 small plastic parts out of a mold cavity using 628N of push force at 0.5MPa, where the CM round-end allows a pivoting ejector arm to clear the mold base.
Pushes a 125mm stroke actuator to redirect small packaged goods on a conveyor line, relying on the G1/4 port for rapid extension and retraction cycles.
Holds a circuit board fixture in place during automated electrical testing, using the -S magnet and a CS1-M sensor to verify the clamp is fully retracted before testing begins.
To replace the MAL40X125-S-CM, order the MBL40X125-S-CM. Confirm your 40mm bore, 125mm stroke, G1/4 port, and PT tapered thread. This SKU specifies a CM round-end back cover, which is ideal for directly mounting a rod clevis or knuckle that must articulate. Because it has the -S magnet, plan to upgrade your sensors from the legacy CS1-M or DS1-M to the modern CMSG, DMSG, or EMSG switches used by the MBL. If your application requires adjustable end-cushioning rather than the fixed rubber bumper, step up to the MBLC variant.
For sizing flexibility, stepping down to the 32mm bore yields 402N of push force at 0.5MPa, while stepping up is not an option as 40mm is the largest MAL mini round bore. A plain MBL does not hold its position or load when air is lost, as the rod drifts; the bumper only softens the stroke end. For a held load, use an external rod lock or a pilot-operated check valve. At 125mm stroke, side-load tolerance is moderate due to the 16mm rod, so ensure the CM cover articulation absorbs any angular misalignment.
Upgrade checklist
Yes, the MAL40X125-S-CM is discontinued. The exact drop-in replacement is the MBL40X125-S-CM, which matches the 40mm bore, 125mm stroke, G1/4 port, and CM round-end mounting. You must update your sensors, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
The 40mm bore provides a push force of 628N and a pull force of 528N at 0.5MPa. At 0.7MPa, the push force is 880N. The maximum theoretical force is 128kgf at 1.0MPa.
