This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50SCASDB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50SCASDB 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 MAL40X50SCASDB (Discontinued) -> MBL40X50SCASDB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X50SCASDB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50SCASDB is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Delivering 628 N of push force at 0.5 MPa, it features a 40 mm bore, 50 mm stroke, and a robust Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. The exact drop-in replacement is the MBL40X50SCASDB, matching the original bore, stroke, 128 kgf maximum output, G1/4 port, CA pivot cover, and SDB mount exactly.
This specific SKU includes a built-in -S magnet for position detection. The legacy MAL magnet interfaces with older CS1-M and DS1-M reed switches, whereas the modern MBL replacement transitions to CMSG, DMSG, and EMSG solid-state sensors. A key structural upgrade differentiates the two generations: the obsolete MAL body relies on threaded front and back covers, while the current MBL utilizes a riveted rolling-packed body for superior structural integrity.

The MBL40X50SCASDB 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.

Uses the 628 N push force at 0.5 MPa to knock finished plastic parts out of tight mold cavities where the SDB pivot bracket accommodates slight misalignment.
Pivots a sorting flap on a logistics conveyor belt; the CA clevis back cover swings freely to absorb arcing motion during high-speed parcel routing.
Extends a 50 mm stroke blocking arm on an assembly line pallet conveyor, relying on the 128 kgf maximum output to halt heavy workpiece pallets safely.
To replace the MAL40X50SCASDB, order the MBL40X50SCASDB. Verify your installation requirements against the 40 mm bore, 50 mm stroke, G1/4 port, and default PT tapered thread. This configuration pairs a CA pivot back cover with an SDB pivot bracket, allowing the cylinder to swing on a pin to absorb arcing loads. If your mechanism requires adjustable end-of-stroke cushioning rather than the fixed rubber bumper found on the MAL, step up to the MBLC variant on the current line. Note that a plain MAL or MBL cylinder does not hold its load when air pressure is lost; the rod will drift. For safety against falling loads, install an external pilot-operated check valve or a dedicated rod lock.
If you are re-evaluating your force requirements, you can step down to the 32 mm bore (delivering 402 N push at 0.5 MPa) for lighter duties, or step up to the 50 mm bore class for heavier demands. Keep in mind that the small 8-16 mm rod diameter on these mini cylinders inherently limits side-load tolerance. Even at this 50 mm stroke, if your application induces lateral stress, rely on the CA pivot mechanism to articulate, or add an external guide rail to prevent rod bending.
Upgrade checklist
Yes, the MAL40X50SCASDB is discontinued. The exact drop-in replacement is the MBL40X50SCASDB. It matches the original 40 mm bore, 50 mm stroke, G1/4 port, CA pivot cover, and SDB mounting bracket. The main upgrade is a riveted rolling-packed body replacing the old threaded covers, and the -S magnet now uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The MAL40X50SCASDB operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s. At 0.5 MPa it provides 628 N of push force and 528 N of pull force. At 0.7 MPa the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It features a Ø16 mm carbon-steel rod with an M12x1.25 rod-end thread.
