This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50CASDB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50CASDB 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 MAL40X50CASDB (Legacy) -> MBL40X50CASDB 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 MBL40X50CASDB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50CASDB is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 40 mm bore and a 50 mm stroke. The exact drop-in replacement is the MBL40X50CASDB, which matches the original bore, stroke, output force, G1/4 port, and SDB mounting configuration exactly.
This legacy SKU features a CA pivot clevis back cover paired with an SDB pivot bracket, allowing the body to swing on a pin to absorb arcing loads. Unlike the older MAL design with threaded front and back covers, the modern MBL replacement utilizes a riveted rolling-packed body for enhanced structural integrity. Because this specific model lacks the -S magnet option, it cannot support a position sensor; if detection is needed on the new MBL, you would order the -S version and use current CMSG, DMSG, or EMSG switches instead of the obsolete CS1-M or DS1-M series.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X50CASDB 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.

Swings on its SDB pivot bracket to push 20kg wooden pallets off a packaging line, utilizing the 628 N push force at 0.5 MPa without rigidly binding during the arcing motion.
Kicks small aluminum brackets out of a die press using its 50 mm stroke, relying on the fixed rubber bumper to soften the impact at the end of the extension cycle.
Folds corrugated cardboard flaps on a sealing machine where the CA clevis allows the body to pivot slightly as the box height varies, preventing rod bending.
To replace the MAL40X50CASDB, order the MBL40X50CASDB. Verify your setup retains the 40 mm bore, 50 mm stroke, PT threaded G1/4 port, and the combination of the CA pivot back cover with the SDB pivot bracket. If your application requires end-of-stroke cushioning, note that the MAL only has a fixed rubber bumper; you should step up to the current MBLC version for an adjustable air cushion. Furthermore, a plain cylinder does not hold its load when air pressure is lost—the rod will drift—so install an external pilot-operated check valve if you need fail-safe positioning.
When sizing, consider stepping down to the 32 mm bore if you need less force, which provides 402 N push at 0.5 MPa. If you need more power, the 40 mm is the largest available bore in this mini series, so for higher force requirements you would need to transition to a different cylinder family entirely. The 16 mm carbon-steel rod with 20 um hard chrome plating offers low side-load tolerance, but the CA and SDB pivot combination effectively manages angular misalignment.
Upgrade checklist
Yes, the MAL40X50CASDB is discontinued. The exact drop-in replacement is the MBL40X50CASDB. It matches the 40 mm bore, 50 mm stroke, 628 N push force, G1/4 port, and CA/SDB pivot mounting. The new MBL uses a riveted rolling-packed body instead of the older threaded covers.
The force ratings are 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. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor; the older MAL -S versions used CS1-M or DS1-M switches, while the MBL replacement uses CMSG, DMSG, or EMSG sensors.
