This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X190U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X190U 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 MAL40X190U (Discontinued) -> MBL40X190U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 190mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X190U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X190U is a discontinued double-acting aluminum mini round cylinder engineered for compact actuation. Delivering 628 N of push force at 0.5 MPa (528 N pull), it utilizes a G1/4 port and a 16 mm carbon-steel rod with 20 um hard chrome plating. The U suffix denotes a rigid flat-end back cover, making the rear non-articulating for rigid mounting. AirTAC replaced this legacy unit with the MBL40X190U, a drop-in upgrade retaining the exact bore, stroke, port size, and output force.
Unlike the older MAL body which relies on threaded front and back covers, the MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Because this specific SKU lacks a built-in magnet, it cannot accept any position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease alongside a self-lubricating front-cover bearing guide. Impact at end-of-stroke is absorbed by a fixed rubber bumper, which softens the stop but does not lock the load.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X190U 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 MBL40X190U 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 628 N push force at 0.5 MPa, this 40 mm bore cylinder acts as a rigid stop gate for 190 mm of travel on conveyor lines carrying heavy packaged goods.
The flat-end U cover provides a rigid rear mount for ejecting molded plastic parts, using the 16 mm hard-chrome rod to withstand 190 mm of repetitive extraction travel.
Delivering 528 N of pull force at 0.5 MPa, the double-acting retract stroke securely folds heavy cardboard flaps on automated packaging machinery within tight spatial constraints.
To replace the MAL40X190U, order the exact MBL40X190U drop-in equivalent. Verify your setup accommodates the U flat-end back cover for rigid, non-pivot mounting and the default PT tapered port thread. Since this unit lacks the -S magnet, no position sensing is possible without upgrading to an -S variant (which shifts sensors from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG family). If your application requires adjustable end-cushioning rather than a fixed rubber bumper, step up to the current MBLC series.
For sizing flexibility, stepping down to a 32 mm bore yields 402 N push at 0.5 MPa, while stepping up to a larger profile cylinder provides higher force. Note that a plain bumper does not hold a load when air pressure is lost; the rod will drift, requiring an external rod lock for fail-safe positioning. Furthermore, the 190 mm stroke combined with a 16 mm rod dictates careful side-load management; rigid U-end mounting transfers lateral stress directly to the rod, so an external guide rail is recommended to prevent premature bearing wear.
Upgrade checklist
Yes, the MAL40X190U is discontinued. The exact drop-in replacement is the MBL40X190U, which matches the 40 mm bore, 190 mm stroke, G1/4 port, and U flat-end mounting. The newer MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor.
