This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X125-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X125-U 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-U (Discontinued) -> MBL40X125-U 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-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X125-U is a discontinued double-acting mini round cylinder with a 40mm bore and 125mm stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa, utilizing a G1/4 port and a rigid flat-end U back cover. AirTAC replaced this legacy unit with the MBL40X125-U, a drop-in alternative retaining the exact stroke, output force, port size, and mounting interface.
This SKU lacks a built-in magnet, so it cannot support position sensing. The original MAL body uses threaded front and back covers, whereas the MBL upgrade features a riveted rolling-packed body for equal strength. Additionally, the MAL relies on a fixed rubber bumper for end-of-stroke damping, while the current MBLC variant offers an adjustable air cushion if you need softer deceleration.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X125-U 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 MBL40X125-U 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.
Drives mechanical folding arms on packaging lines to close top flaps, using the 628N push force at 0.5 MPa to overcome cardboard resistance.
Ejects small stamped metal parts from a die bed, relying on the 125mm stroke to clear the tooling before the strip advances.
Pushes lightweight pallets or tote boxes onto a side conveyor lane, where the rigid flat-end U cover withstands direct impact without pivot wear.
To replace the MAL40X125-U, order the MBL40X125-U and confirm your 40mm bore, 125mm stroke, G1/4 port, PT thread, and flat-end U back cover. Because this configuration has no magnet, you cannot mount a sensor; if you need position detection, upgrade to an MBL40X125-S-U and switch from the legacy CS1-M/DS1-M to the modern CMSG/DMSG/EMSG switches. The cylinder uses a carbon-steel rod with 20um hard chrome and a self-lubricating bearing guide.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5 MPa, while stepping up is not an option as 40mm is the largest MAL mini round size. A plain bumper does not lock the rod, so add an external pilot-operated check valve if you must hold a load during air loss. At 125mm stroke, side-load tolerance is moderate, but the 16mm rod handles it well if guided.
Upgrade checklist
Yes, the MAL40X125-U is discontinued. The exact drop-in replacement is the MBL40X125-U, which matches the 40mm bore, 125mm stroke, G1/4 port, and flat-end U mounting. The MBL uses a riveted body instead of threaded covers, but performance remains identical.
It delivers 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept a position sensor; you must buy an -S model and use CMSG/DMSG/EMSG switches on the MBL replacement.
