This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X45U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X45U 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 MAL40X45U (Discontinued) -> MBL40X45U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 45mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X45U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X45U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 45mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and a 16mm carbon-steel rod with 20um hard-chrome plating. Because this legacy series is end-of-life, the exact drop-in replacement is the MBL40X45U, which matches the original bore, stroke, output force, port size, and mounting accessories exactly.
This specific SKU features a U flat-end back cover for rigid rear mounting and lacks a built-in magnet, meaning it cannot accept any position sensor. The original MAL body used threaded front and back covers on the barrel, whereas the current MBL replacement features a riveted rolling-packed body for enhanced structural integrity. Both generations rely on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion, though the modern MBLC variant does offer adjustable cushioning if your application requires precise deceleration.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X45U 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 MBL40X45U 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 0.5MPa to eject small plastic parts from tight mold cavities, using the rigid U flat-end cover to maintain precise alignment against the machine platen.
Drives a 45mm stroke diverter arm on a packaging line, using the G1/4 port for rapid actuation to push cartons onto secondary routing belts without delay.
Actuates a testing head onto printed circuit boards, where the fixed rubber bumper safely absorbs the short 45mm stroke impact without damaging delicate electronic components.
To replace the MAL40X45U, order the MBL40X45U and verify your 40mm bore, 45mm stroke, G1/4 port, and PT tapered thread requirements. Confirm your flat-end U back cover and your specific mounting accessory, as the MBL keeps the identical mounting footprint. Because this SKU has no -S magnet, it cannot support a position sensor; if you need rod detection, you must upgrade to an MBL40X45US and switch from the old CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG family. The 45mm stroke is short, but if you need to step down, the 32mm bore provides 402N push at 0.5MPa; if you need to step up, note 40mm is the largest MAL mini-round size available. For load holding when air is lost, add an external rod lock, as the rubber bumper will not prevent drift.
Upgrade checklist
Yes, the MAL40X45U is discontinued. The exact drop-in replacement is the MBL40X45U, which offers the same 40mm bore, 45mm stroke, 628N push force, G1/4 port, and U flat-end mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
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. This specific SKU lacks a built-in magnet, so it cannot accept a position sensor; adding detection requires switching to an MBL40X45US model using CMSG/DMSG/EMSG switches.
