This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X500-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X500-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 MAL40X500-S-U (Discontinued) -> MBL40X500-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 500mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X500-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X500-S-U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 500mm stroke. It delivers a robust 628 N push force at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The U suffix denotes a flat-end back cover for rigid, straight-line mounting. As a legacy component, its exact drop-in replacement is the MBL40X500-S-U, which matches the bore, stroke, output force, port size, and mounting accessories perfectly.
Two critical engineering details define this transition. First, the original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Second, the -S magnet on this legacy unit interfaces with the older CS1-M and DS1-M reed switches; upgrading to the MBL40X500-S-U requires migrating to the current CMSG, DMSG, or EMSG sensor families to detect rod position.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X500-S-U 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 MBL40X500-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 628 N of push at 0.5 MPa to eject plastic parts from injection molds, where the 500mm stroke accommodates deep-cavity tooling.
Transfers heavy wooden pallets off a high-throughput conveyor line, utilizing the flat-end U cover for rigid mounting against the machine frame.
Drives a mechanical arm to fold large corrugated carton flaps during automated packaging runs, relying on the 40mm bore's 880 N thrust at 0.7 MPa.
To replace the MAL40X500-S-U, order the MBL40X500-S-U. Confirm your installation requires the 40mm bore delivering 628 N push at 0.5 MPa, along with the default PT tapered port thread and the U flat-end back cover. Because this SKU includes the -S magnet, you must update your sensing setup: the legacy CS1-M and DS1-M switches are incompatible with the MBL, which requires current CMSG, DMSG, or EMSG sensors. The MAL uses a fixed rubber bumper, so if your application demands adjustable end-of-stroke cushioning to absorb the kinetic energy of a 500mm stroke, step up to the MBLC variant on the current line.
At a 500mm stroke, the 16mm carbon-steel rod is highly susceptible to bending under side loads, requiring an external guide rail or a pivot mount to prevent premature seal failure. If you need to adjust sizing, stepping down to the 32mm bore drops the push force to 402 N at 0.5 MPa, while stepping up is not an option as 40mm is the largest available bore in this mini round series. Note that a plain cylinder does not hold its load when air pressure is lost; the rod will drift, so incorporate an external pilot-operated check valve if position holding is critical.
Upgrade checklist
Yes, the MAL40X500-S-U is discontinued. The exact drop-in replacement is the MBL40X500-S-U, which offers the same 40mm bore, 500mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and U flat-end back cover. You must update your sensors, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M and DS1-M.
The 40mm bore provides a push force of 628 N and a pull force of 528 N at 0.5 MPa, a push force of 880 N at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a G1/4 port and an M12x1.25 rod-end thread.
