This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X120SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X120SCM 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 MAL40X120SCM (Discontinued) → MBL40X120SCM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 120mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X120SCM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X120SCM is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Delivering 628 N of push force at 0.5 MPa, it features a 40 mm bore, a 120 mm stroke, and a G1/4 port. The direct drop-in replacement is the MBL40X120SCM, which matches the original bore, stroke, output force, and port size exactly. This CM round-end variant includes a built-in magnet for position sensing.
Unlike the legacy MAL body that used threaded front and back covers, the modern MBL replacement features a riveted rolling-packed body for equal rigidity. The -S magnet on this MAL unit interfaces with older CS1-M or DS1-M reed switches, whereas upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor families. The internal piston relies on a heterogeneous two-way seal that retains grease, while the carbon-steel rod is protected by a 20 µm hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X120SCM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X120SCM 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.

Using its 880 N push force at 0.7 MPa, this cylinder reliably ejects stamped metal parts from a 20-ton pneumatic press bed in tight tooling layouts.
The CM round-end pivot allows smooth articulation when swinging a diverter arm to route heavy cardboard cartons across a merging conveyor belt.
Provides robust 628 N push force at 0.5 MPa to open and close lightweight sliding safety gates on automated pallet wrapping machinery.
To replace the MAL40X120SCM, order the MBL40X120SCM. Confirm the 40 mm bore, 120 mm stroke, G1/4 port, and PT tapered thread are specified. This SKU includes a CM round-end back cover, which is ideal for accommodating slight rotational misalignment, and an -S magnet, meaning you must upgrade your legacy CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG family. The MAL uses a fixed rubber bumper; if your application needs adjustable end-of-stroke damping, step up to the current MBLC variant.
For sizing flexibility, stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa, while stepping up is not an option as 40 mm is the largest MAL mini round bore. At 120 mm of stroke, side-load tolerance is already low due to the 16 mm rod, so utilizing the CM round-end pivot is highly recommended to absorb arcing loads. Remember that a plain MAL or MBL does not hold its position when air pressure is lost; the rod will drift, so deploy an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X120SCM is discontinued. The exact drop-in replacement is the AirTAC MBL40X120SCM, which shares the same 40 mm bore, 120 mm stroke, G1/4 port, and CM round-end mounting. You also keep the -S magnet, but you must upgrade from the older CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG sensors.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa.
