This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X250-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X250-S-CM 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 MAL40X250-S-CM (Discontinued) -> MBL40X250-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 250mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X250-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X250-S-CM is a discontinued double-acting aluminum mini round cylinder with a 40 mm bore and 250 mm 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. The exact drop-in replacement is the MBL40X250-S-CM, which matches the bore, stroke, output force, port size, and mounting accessories exactly.
This legacy unit features a CM round-end back cover and a built-in -S magnet. The older MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Additionally, the -S magnet on this discontinued cylinder operates with legacy CS1-M or DS1-M reed switches; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor families.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X250-S-CM 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.

Diverts flat packaging pallets on a 90-degree conveyor junction using 628 N of push force at 0.5 MPa to overcome carton friction.
Stages filled cardboard cases into a case sealer, using the 250 mm stroke to clear the incoming packaging line completely.
Pushes rejected metal castings into a reject chute, relying on the CM round-end back cover to accommodate slight angular misalignment.
To replace the MAL40X250-S-CM, order the MBL40X250-S-CM. Confirm your 40 mm bore, 250 mm stroke, G1/4 port, PT thread, CM round-end back cover, and -S magnet. Because the -S magnet is present, note that your existing CS1-M or DS1-M sensors will not fit the new MBL body; you must upgrade to CMSG, DMSG, or EMSG switches. If your application needs an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the MBLC variant on the current line. The 250 mm stroke creates a long lever arm on the 16 mm rod, so side-load tolerance is low; use an external guide rail or a pivot mount to prevent rod bending. If you need to adjust force, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while stepping up to a larger profile cylinder provides higher force. Remember that a plain MAL or MBL does not hold its load when air is lost—the rod drifts—so install an external rod lock or pilot-operated check valve for vertical loads.
Upgrade checklist
Yes, the MAL40X250-S-CM is discontinued. The exact drop-in replacement is the MBL40X250-S-CM, which shares the same 40 mm bore, 250 mm stroke, G1/4 port, and CM round-end mounting. You will need to upgrade your sensors because the legacy CS1-M and DS1-M switches used on the MAL -S magnet are replaced by CMSG, DMSG, or EMSG switches on the MBL.
The 40 mm bore 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 uses a fixed rubber bumper for end-of-stroke impact absorption and lacks an adjustable cushion; if adjustable cushioning is required, use the current-line MBLC variant.
