This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X30U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X30U 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 MAL40X30U (Discontinued) → MBL40X30U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 30mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X30U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X30U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 30mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The U designation indicates a rigid flat-end back cover, making it suitable for straightforward inline mounting arrangements.
The exact drop-in replacement is the MBL40X30U, matching the bore, stroke, output force, port size, and mounting hardware. A key upgrade in the MBL is its riveted rolling-packed body, which replaces the threaded front and back covers found on this legacy MAL. Additionally, because this specific SKU lacks a built-in magnet, it cannot accept a position sensor; if detection is needed on the new MBL, you must order an -S version which uses the modern CMSG, DMSG, or EMSG switch families rather than the older CS1-M/DS1-M sensors.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X30U 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 MBL40X30U 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.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Provides 628N of push force at 0.5MPa to eject small plastic parts from mold cavities, where the short 30mm stroke delivers rapid cycling without rod overhang.
Actuates a short diverting flap on a packaging conveyor, utilizing the rigid U flat-end back cover to maintain strict inline alignment during heavy carton deflection.
Deploys a physical stop block for lightweight pallets on a low-profile roller bed, absorbing impact with its fixed rubber bumper at the end of the 30mm extension.
To replace the MAL40X30U, order the MBL40X30U, confirming the 40mm bore, 30mm stroke, G1/4 port, default PT thread, and the U flat-end back cover. If your application requires a position sensor, note that this legacy SKU cannot support one without changing the part code to include an S, which subsequently requires upgrading to CMSG/DMSG/EMSG switches on the MBL. If you need to step down to the 32mm bore, expect 402N of push force at 0.5MPa; stepping up is not an option as 40mm is the largest standard MAL mini round size. The MAL uses a fixed rubber bumper for end-of-stroke deceleration; if your process demands an adjustable air cushion, you must switch to the MBLC variant on the current line. Remember that a plain cylinder does not hold its position or load when air is lost, as the rod drifts and the bumper provides no locking function.
Upgrade checklist
Yes, the MAL40X30U is discontinued. The exact drop-in replacement is the MBL40X30U, which matches the 40mm bore, 30mm stroke, 628N push force, G1/4 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed construction instead of the threaded covers used on the MAL.
The 40mm bore generates 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks an S designation for a built-in magnet, it cannot accept a position sensor; if detection is required, you must order the MBL40X30US and use CMSG, DMSG, or EMSG switches.
