This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X20U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X20U 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 MAL40X20U (Discontinued) → MBL40X20U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 20mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X20U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X20U is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces requiring high thrust. Delivering 628 N of push force at 0.5 MPa, this 40 mm bore unit utilizes a 16 mm carbon-steel rod with 20 um hard-chrome plating. Because the MAL series has reached end-of-life, AirTAC mandates the MBL40X20U as the exact drop-in replacement. It matches the original bore, 20 mm stroke, G1/4 port, and U flat-end back cover perfectly.
This specific SKU features a U-type flat-end back cover for rigid, non-pivoting mounting and lacks a built-in magnet, meaning it cannot accept position sensors. A notable upgrade in the MBL successor is the transition from the MAL's threaded front and back covers to a riveted rolling-packed body. Both generations rely on a fixed rubber bumper rather than an adjustable air cushion, though the current MBLC variant does offer adjustable cushioning if your application demands softer end-of-stroke deceleration.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X20U 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 the robust 628 N push force needed to eject dense plastic parts from tight mold cavities where a smaller 32 mm cylinder would stall.
Acts as a rigid halt mechanism using the U flat-end mount to absorb the momentum of heavy transfer pallets arriving at an assembly workstation.
Secures thick, multi-layer printed circuit boards against a testing bed, using the short 20 mm stroke to rapidly apply and release 628 N of clamping pressure.
To replace the discontinued MAL40X20U, order the MBL40X20U. Verify your setup accommodates the G1/4 port and M12x1.25 rod-end thread. Because this SKU has no -S magnet, it cannot support a sensor; if you need position detection, step up to an MBL40X20US and prepare to upgrade from the legacy CS1-M or DS1-M switches to the modern CMSG, DMSG, or EMSG families. If your fixture requires arcing movement rather than the rigid U flat-end, select the CA pivot cover instead.
For sizing flexibility, stepping down to a 32 mm bore drops the push force to 402 N at 0.5 MPa, while this 40 mm bore provides 628 N. As the largest standard MAL mini round cylinder, there is no larger neighbor in this family. Note that the fixed rubber bumper is not a locking device; the rod will drift if air pressure is lost, so employ an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X20U is discontinued. The exact drop-in replacement is the AirTAC MBL40X20U, which shares the identical 40 mm bore, 20 mm stroke, 628 N force, G1/4 port, and U flat-end back cover. The MBL upgrades the body construction from threaded covers to a riveted rolling-packed design.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. This SKU lacks a magnet, so it cannot accept position sensors.
