This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL40X50-U-FA, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL40X50-U-FA (Discontinued) -> MBL40X50-U-FA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL40X50-U-FA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-U-FA is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 50mm stroke. It delivers a robust 628N push force at 0.5MPa and uses a G1/4 port. The direct replacement is the MBL40X50-U-FA, which matches the original bore, stroke, output force, port size and FA flange mounting exactly. You simply order the MBL equivalent for a seamless upgrade.
This legacy SKU features a U flat-end back cover for rigid rear mounting and an FA flange for front attachment. Because this specific model lacks the -S magnet, it cannot accept a position sensor. Note that the older MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equal structural strength. The original MAL also relies on a fixed rubber bumper rather than an adjustable cushion.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X50-U-FA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 40 | Bore size in mm (20/25/32/40). |
| ×50 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBL uses CMSG/DMSG/EMSG). |
| CA / U / CM | Back cover: CA pivot, U flat-end or CM round-end. |
Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Uses the 628N push force at 0.5MPa to reliably shove populated circuit board trays sideways onto secondary packaging lines.
Short 50mm stroke rapidly knocks plastic parts out of small molds, relying on the FA flange for rigid front-face mounting.
Provides the heavy 128kgf peak thrust needed to fold thick corrugated cardboard flaps closed prior to case sealing.
To replace the MAL40X50-U-FA, order the MBL40X50-U-FA. Verify your 40mm bore, 50mm stroke, G1/4 port, PT tapered thread, U flat-end back cover and FA flange mounting before checkout. Since this SKU has no -S magnet, you cannot mount a sensor; if you now need position detection, upgrade to an MBL40X50S-U-FA and use the modern CMSG, DMSG or EMSG switches instead of the legacy CS1-M/DS1-M.
If you need to resize, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the 50mm bore is not available in this mini series. A plain MBL does not hold its load when air pressure drops, so add an external rod lock for vertical positioning. If end-of-stroke damping is insufficient, step up to the MBLC variant which offers an adjustable air cushion the MAL never had.
Upgrade checklist
Yes, the MAL40X50-U-FA is discontinued. The direct replacement is the MBL40X50-U-FA, which matches the 40mm bore, 50mm stroke, 628N force, G1/4 port and FA flange. The MBL uses a riveted body instead of threaded covers but retains full mechanical compatibility.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it provides 880N push; and the maximum theoretical force is 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept any position sensor.
