This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X125-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X125-S-U 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-U (Discontinued) -> MBL40X125-S-U 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-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X125-S-U 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 0.5 MPa, utilizing a G1/4 port and a 16mm carbon-steel rod with a 20um hard-chrome plating. The exact drop-in replacement is the MBL40X125-S-U, which matches the original bore, stroke, output force, port size, and U flat-end mounting configuration.
This legacy SKU features a built-in magnet (-S) for position sensing and a fixed rubber bumper. The older MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Additionally, the -S magnet on this discontinued model interfaces with legacy CS1-M or DS1-M reed switches, while the MBL upgrade requires the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X125-S-U 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 MBL40X125-S-U 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 0.5 MPa to eject small plastic parts from injection mold cavities, where the fixed rubber bumper safely absorbs the 125mm stroke impact without damaging the mold face.
Drives a mechanical arm to fold corrugated cardboard flaps on packaging lines, using the rigid U flat-end back cover to maintain alignment under the 528N retract load.
Actuates a routing gate on a conveyor system to sort small parcels, relying on the self-lubricating front-cover bearing guide to handle the 16mm rod movement over continuous cycles.
To replace the MAL40X125-S-U, order the MBL40X125-S-U. Confirm your bore, 125mm stroke, G1/4 port, and PT tapered thread are retained. The U flat-end back cover provides a rigid rear mount, differing from the CA pivot clevis which allows arcing side-play. Because this SKU includes the -S magnet, you must upgrade your position sensors: the legacy CS1-M and DS1-M switches will not fit the MBL, so select CMSG, DMSG, or EMSG switches instead. If your application requires adjustable end-cushioning rather than the fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing, if 628N of push force at 0.5 MPa is excessive, step down to the 32mm bore (402N push). If you need more power, note that 40mm is the largest standard MAL mini round bore, so exceeding 128 kgf at 1.0 MPa requires migrating to a larger ISO 15552 profile cylinder. Since the stroke is 125mm, the 16mm rod is manageable, but a plain double-acting cylinder drifts when air is lost—the bumper softens the end of stroke but does not lock the load, so add an external rod lock or pilot-operated check valve for position holding.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X125-S-U, which shares the same 40mm bore, 125mm stroke, G1/4 port, U flat-end cover, and 628N push force. You must upgrade your sensors, as the MBL body uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M models.
At 0.5 MPa, the 40mm bore provides 628N of push force and 528N of pull force. At 0.7 MPa, the push force reaches 880N. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
