This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X280SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X280SU 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 MAL40X280SU (Discontinued) → MBL40X280SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 280mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X280SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X280SU is a discontinued double-acting compact aluminum mini round cylinder. It delivers a robust 628 N push force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard chrome plating. The exact drop-in replacement is the MBL40X280SU, matching the 40 mm bore, 280 mm stroke, G1/4 port, and flat-end U back cover.
This legacy unit features a built-in -S magnet for position sensing with older CS1-M or DS1-M switches. The modern MBL replacement upgrades you to a riveted rolling-packed body instead of the MAL's threaded covers, and requires current CMSG, DMSG, or EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, though it cannot hold the load if air pressure is lost.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X280SU 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 MBL40X280SU 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.

Actuates a 280 mm diverter gate in end-of-line packaging, using the 628 N push force at 0.5 MPa to reliably redirect heavy loaded pallets onto a secondary belt.
Provides 528 N of pull force at 0.5 MPa to hold an electronics assembly fixture securely during a 280 mm routing cycle, relying on the -S magnet for end-of-stroke confirmation.
Drives a 280 mm folding arm on a high-speed cartoning machine, where the fixed rubber bumper absorbs the kinetic energy of 40 mm bore thrust at the end of each stroke.
To replace the MAL40X280SU, order the MBL40X280SU. Verify your 280 mm stroke, G1/4 port, PT thread, and the rigid U flat-end rear cover. Because this SKU includes the -S magnet, plan to swap your legacy CS1-M/DS1-M switches for CMSG/DMSG/EMSG sensors on the new body. If your cycle speeds demand adjustable cushioning instead of the fixed rubber bumper, step up to the MBLC40 variant on the current line.
For sizing flexibility, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while no larger standard mini-round exists. At 280 mm stroke, the 16 mm rod is highly susceptible to bending under side loads; use an external guide rail or a pivot mount to prevent premature seal failure. Remember that a standard bumper softens impact but does not lock the rod—add a pilot-operated check valve if you must hold a load vertically during an air-loss event.
Upgrade checklist
Yes, the MAL40X280SU is discontinued. The exact drop-in replacement is the MBL40X280SU, which matches the 40 mm bore, 280 mm stroke, 628 N push force, G1/4 port, and U flat-end cover. You simply order the MBL equivalent, but note the -S magnet now requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M/DS1-M switches.
The 40 mm bore delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a G1/4 port and a 16 mm rod with an M12x1.25 thread.
