This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50-S-CA 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 MAL40X50-S-CA (Discontinued) -> MBL40X50-S-CA 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 MBL40X50-S-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-S-CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 50mm stroke. It delivers a robust 628 N push and 528 N pull at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. AirTAC replaced this legacy unit with the MBL40X50-S-CA, a drop-in alternative that matches the original bore, stroke, output force, port size, and CA pivot mounting for a seamless swap.
This specific SKU features a built-in -S magnet for position sensing, which on the MAL works with older CS1-M or DS1-M reed switches. When upgrading to the MBL, you must switch to the current CMSG, DMSG, or EMSG sensor family. The original MAL body uses threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for equally robust performance. It relies on a fixed rubber bumper for end-of-stroke damping and a heterogeneous two-way seal that retains grease for long-term lubrication.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X50-S-CA 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 628 N of push force at 0.5 MPa to drive heavy cardboard folding mechanisms on continuous-flow packaging lines.
Uses the CA pivot back cover to swing a diverter arm smoothly across a conveyor belt, absorbing lateral arc stresses.
Utilizes the -S magnet and CS1-M sensor to confirm clamp extension before an automated PCB bed-of-nails tester descends.
To replace the MAL40X50-S-CA, order the MBL40X50-S-CA. Verify your existing setup: a 40mm bore, 50mm stroke, G1/4 port, PT thread form, and the CA pivot back cover that allows the cylinder to swing on a pin for arcing loads. Because this unit has the -S magnet, plan to upgrade your legacy CS1-M or DS1-M switches to CMSG, DMSG, or EMSG sensors to fit the MBL groove. If your application requires adjustable cushioning rather than the fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 32mm bore reduces the push force to 402 N at 0.5 MPa, while stepping up to a larger profile cylinder yields higher forces. Note that a plain MAL or MBL does not hold its position or load when air is lost, as the rod drifts; the bumper only softens the stroke end. For a held load, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X50-S-CA is discontinued. The exact drop-in replacement is the MBL40X50-S-CA, which matches the 40mm bore, 50mm stroke, 628 N push force, G1/4 port, and CA pivot mounting. You simply order the MBL equivalent.
At 0.5 MPa it delivers 628 N push and 528 N pull, reaching 880 N push at 0.7 MPa, with a theoretical max of 128 kgf at 1.0 MPa. The -S magnet works with older CS1-M or DS1-M switches; the MBL replacement requires CMSG, DMSG, or EMSG sensors.
