This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X120U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X120U 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 MAL40X120U (Discontinued) -> MBL40X120U 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 MBL40X120U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X120U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 120mm stroke. It delivers 628N push and 528N pull at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X120U, which matches the bore, stroke, output force, port, and mounting dimensions exactly.
This legacy SKU features a U flat-end back cover for rigid rear mounting and has no internal magnet, meaning it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both designs rely on a fixed rubber bumper for end-of-stroke damping; if an adjustable air cushion is required, the current MBLC variant must be specified instead.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X120U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X120U 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.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Provides 628N of push force at 0.5 MPa to eject small plastic parts from injection mold cavities, utilizing the 120mm stroke to clear the mold plate fully.
Actuates a rigid diverter arm on a packaging conveyor, using the U flat-end back cover for a hard-mounted pivot that handles the 528N retract load reliably.
Folds heavy corrugated carton flaps during case packing, where the 40mm bore's 880N thrust at 0.7 MPa easily overcomes cardboard resistance without stalling.
To replace the MAL40X120U, order the MBL40X120U. Confirm the 40mm bore, 120mm stroke, G1/4 port, and PT tapered thread. This U flat-end configuration provides rigid rear mounting. Because this SKU lacks the -S magnet, it cannot support a sensor; if position detection is needed, order an MBL40X120US and note that the modern switch family changes from the legacy CS1-M/DS1-M to the current CMSG/DMSG/EMSG series.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5 MPa, while stepping up is not an option as 40mm is the largest standard MAL mini round bore (max 128 kgf at 1.0 MPa). The 120mm stroke exceeds 300mm? No, but it still requires attention: the 16mm carbon-steel rod has low side-load tolerance, so an external guide or pivot mounting is recommended to prevent rod bending. A plain cylinder does not hold loads when air is lost; add an external rod lock for fail-safe holding.
Upgrade checklist
Yes, the MAL40X120U is discontinued. The exact drop-in replacement is the MBL40X120U, which offers the same 40mm bore, 120mm stroke, G1/4 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design while maintaining identical output force.
The 40mm bore generates 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. This specific SKU lacks the -S magnet, so it cannot accept a position sensor; adding a sensor requires the MBL40X120US and CMSG/DMSG/EMSG switches.
