This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X45SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X45SCA 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 MAL40X45SCA (Discontinued) -> MBL40X45SCA 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 MBL40X45SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X45SCA is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 45mm 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. AirTAC replaced this legacy unit with the MBL40X45SCA, a drop-in alternative retaining the exact same bore, stroke, output force, port size, and CA pivot mounting interface.
This specific SKU includes a built-in magnet (-S) for position sensing and a CA pivot back cover designed to swing on a pin for arcing loads. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Additionally, the -S magnet on this legacy cylinder operates with the older CS1-M and DS1-M switches; upgrading to the MBL requires transitioning to the modern CMSG, DMSG, or EMSG sensor families.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X45SCA 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 small plastic parts from injection molds, where the short 45mm stroke delivers rapid retraction within tight machine cavities.
Swings a diverter arm using the CA pivot back cover to route small packages on a conveyor line, leveraging the 880 N push force available at 0.7 MPa for positive shifting.
Folds minor flaps on small packaging cartons, utilizing the fixed rubber bumper to soften the end of stroke and the -S magnet to confirm flap closure to the machine controller.
To replace the MAL40X45SCA, order the MBL40X45SCA, confirming the 40mm bore, 45mm stroke, G1/4 port, and PT thread form. You must also account for the CA pivot back cover, which accommodates arcing loads by swinging on a pin, and the -S magnet, which necessitates a sensor upgrade from the legacy CS1-M/DS1-M to the current CMSG/DMSG/EMSG switches. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the MBLC series.
For sizing flexibility, stepping down to the 32mm bore yields 402 N of push force at 0.5 MPa, while this 40mm bore provides 628 N. Because this cylinder lacks a position lock, the rod will drift if air pressure is lost; a pilot-operated check valve or external rod lock is required to hold a load safely. The 45mm stroke is short enough that side-load tolerance is manageable, though the 16mm carbon-steel rod with 20 um hard chrome plating still relies on the self-lubricating front-cover bearing guide to minimize wear.
Upgrade checklist
Yes, the MAL40X45SCA is discontinued. The exact drop-in replacement is the MBL40X45SCA, which matches the 40mm bore, 45mm stroke, 628 N force, G1/4 port, and CA pivot mounting. The MBL upgrades the body to a riveted rolling-packed design and requires CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The double-acting MAL40X45SCA provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s, driven by filtered air over a 0.1-1.0 MPa pressure range.
