This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X125-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X125-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 MAL40X125-S-CA (Discontinued) → MBL40X125-S-CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 125mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X125-S-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X125-S-CA is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the legacy range, it delivers a robust 628 N push force at 0.5 MPa (880 N at 0.7 MPa) along a 125 mm stroke. AirTAC replaced this unit with the MBL40X125-S-CA, a drop-in alternative that retains the exact 40 mm bore, G1/4 port size, M12x1.25 rod thread, and CA pivot mounting.
This SKU includes a built-in magnet (-S) for position detection and a CA clevis back cover that pivots on a pin to absorb arcing loads. The legacy MAL body relies on threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. If you previously used CS1-M or DS1-M reed switches on this cylinder, note that the MBL successor requires the newer CMSG, DMSG, or EMSG sensor families.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X125-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.

Provides 628 N of push force at 0.5 MPa to eject small plastic parts from a mold cavity, utilizing the 125 mm stroke to clear the tooling entirely.
Swings a routing gate on a packaging line using the CA pivot back cover, absorbing the arcing momentum of passing 40 kg product pallets.
Drives a testing probe head into contact with a circuit board, using the -S magnet to trigger a CS1-M sensor and confirm the 125 mm extend position.
To replace this discontinued unit, order the MBL40X125-S-CA, ensuring you keep the PT tapered port thread, the CA pivot back cover, and the magnet option. If your application requires adjustable air cushioning at the end of stroke—which the fixed rubber bumper on this MAL lacks—you should step up to the MBLC variant on the current line. For sizing flexibility, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while no larger standard mini round bore exists in this family. Because the stroke is 125 mm, the 16 mm rod handles moderate loads well, but a plain cylinder cannot hold a load if air pressure drops; utilize an external rod lock for vertical safety.
Upgrade checklist
Yes, the MAL40X125-S-CA is discontinued. The exact drop-in replacement is the MBL40X125-S-CA, which matches the 40 mm bore, 125 mm stroke, G1/4 port, and CA pivot mounting. The new MBL body uses a riveted rolling-packed design instead of threaded covers, and you must upgrade to CMSG, DMSG, or EMSG sensors since the older CS1-M and DS1-M switches are incompatible.
The 40 mm bore uses a 16 mm carbon-steel rod with an M12x1.25 end thread. At 0.5 MPa it provides 628 N push and 528 N pull force. At 0.7 MPa the push force is 880 N, and the maximum theoretical force is 128 kgf at 1.0 MPa.
