This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X250-S-U-H — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X250-S-U-H 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-U-H (Discontinued) → MBL40X250-S-U-H 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-U-H, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X250-S-U-H is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 250mm stroke. It delivers 628N push and 528N pull at 0.5MPa using its G1/4 port. The exact drop-in replacement is the MBL40X250-S-U-H, matching the force, stroke, and mounting exactly. The legacy MAL features a threaded front and rear cover, whereas the modern MBL uses a riveted rolling-packed body for equally robust performance.
This SKU includes a U flat-end back cover for rigid rear mounting and an internal magnet (-S) for position sensing. Because it is an MAL, the magnet interfaces with the older CS1-M or DS1-M reed switches; upgrading to the MBL means switching to the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod is hardened with 20um chrome plating to resist wear. It uses a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X250-S-U-H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X250-S-U-H 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 628N of push force at 0.5MPa to reliably swing a heavy mechanical divert gate on a packaging conveyor over a 250mm travel distance.
Secures cast aluminum engine blocks during CNC machining, using the U flat-end cover for rigid rear mounting against the fixture plate.
Pushes heavy corrugated cartons into a case erector, using the CS1-M sensor to confirm the 250mm stroke is fully extended before the cycle continues.
To replace this MAL40X250-S-U-H, order the MBL40X250-S-U-H. It is a true drop-in upgrade retaining the 40mm bore, 250mm stroke, G1/4 port, PT thread, U flat-end cover, and magnet. If your application requires an adjustable air cushion to soften end-of-stroke impacts—which the MAL fixed rubber bumper cannot provide—step up to the MBLC40 series. If you need to hold a load vertically without air pressure, note that neither the MAL nor MBL acts as a lock; you must add an external rod lock or pilot-operated check valve.
For sizing flexibility, the next size down is the 32mm bore (delivering 402N push at 0.5MPa), and the next size up is the 50mm profile cylinder (not available in the MAL/MBL mini round family). Because this 250mm stroke exceeds 300mm, the 16mm rod has limited side-load tolerance; use a CA or SDB pivot mount or an external guide rail to prevent rod bending.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X250-S-U-H, offering the same 40mm bore, 250mm stroke, G1/4 port, U flat-end cover, and mounting interface. The main change is that the MBL uses a riveted body instead of threaded covers, and the -S magnet requires upgrading from the old CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG sensors.
At 0.5MPa it provides 628N push and 528N pull. At 0.7MPa the push force is 880N, with a theoretical maximum of 128kgf at 1.0MPa. It operates on filtered air at 0.1-1.0MPa, runs at 30-800mm/s, and uses a fixed rubber bumper rather than an adjustable air cushion.
