This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X70SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X70SU 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 MAL40X70SU (Discontinued) → MBL40X70SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 70mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X70SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X70SU is a discontinued double-acting mini round cylinder featuring a 40mm bore and 70mm stroke. It delivers a robust 628N push and 528N pull force at 0.5MPa, making it the highest output class in this legacy aluminum-barrel series. AirTAC replaced it with the MBL40X70SU, a drop-in alternative retaining the exact same G1/4 port, M12x1.25 rod thread, and U flat-end rear cover.
This SKU includes a built-in magnet (-S) for position detection. A key upgrade detail is the body construction: the MAL uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body. Additionally, the MAL -S magnet interfaces with the older CS1-M / DS1-M switches, while the modern MBL utilizes CMSG / DMSG / EMSG sensors. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal that retains grease for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X70SU 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 MBL40X70SU 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.

Provides 628N of push force at 0.5MPa to eject small plastic parts from injection molds, utilizing the 70mm stroke to clear the mold cavity safely.
Actuates a diverter arm on a packaging conveyor, using the U flat-end cover for rigid mounting and the G1/4 port for high flow to cycle quickly.
Drives a printed circuit board test probe head into contact, relying on the -S magnet and CS1-M/DS1-M switches to confirm the 70mm extend position.
To replace the MAL40X70SU, order the exact MBL40X70SU drop-in equivalent. Verify your setup retains the U flat-end back cover for rigid mounting, the G1/4 port, and the PT tapered thread form. Because this SKU has the -S magnet, plan to upgrade your position sensing from the legacy CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG family used by the MBL. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on the MAL, step up to the MBLC variant on the current line.
For sizing alternatives, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up is not possible within the 40mm maximum mini-round series. Note that a plain MBL does not hold its load when air is lost; the rod drifts. For a held load, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X70SU is discontinued. The exact drop-in replacement is the MBL40X70SU, which shares the same 40mm bore, 70mm stroke, output force, G1/4 port, and U flat-end mounting. You simply order the MBL40X70SU, though you will need CMSG/DMSG/EMSG sensors for the magnet.
The MAL40X70SU provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping and does not feature an adjustable cushion; if you need adjustable cushioning, look at the current MBLC line.
