This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X375SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X375SU 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 MAL40X375SU (Discontinued) → MBL40X375SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 375mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X375SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X375SU is a discontinued double-acting aluminum mini round cylinder. As a 40mm bore unit, it delivers a robust 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. Because this legacy series is end-of-life, AirTAC replaced it with the MBL40X375SU, a drop-in alternative retaining the exact stroke, output force, port size, flat U back cover, and magnet configuration.
This 375mm stroke SKU relies on a fixed rubber bumper to soften end-of-travel impacts rather than an adjustable cushion. The original MAL body features threaded front and back covers, whereas the MBL replacement upgrades to a riveted rolling-packed body. Additionally, the -S magnet on this MAL works with the older CS1-M and DS1-M switches, but the MBL successor requires the current CMSG, DMSG, or EMSG sensor families. A heterogeneous two-way seal retains grease for long-term friction reduction.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X375SU 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 MBL40X375SU 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.

Drives a 375mm stroke to push aluminum pallets between roller conveyor sections using 628N of 0.5MPa push force.
Shifts a heavy sliding machine tool door across its 375mm track, relying on the flat U back cover for rigid alignment.
Extends to fold large packaging flaps on a case erector, utilizing the fixed rubber bumper to prevent end-impact damage.
To replace the MAL40X375SU, order the MBL40X375SU and verify the 40mm bore, 375mm stroke, G1/4 port, and PT tapered thread. Confirm the U flat-end back cover for rigid mounting and the -S magnet, noting the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. If you need to step down, the 32mm neighbor provides 402N push at 0.5MPa; if stepping up is required, the 40mm is the largest MAL bore available. At 375mm, the 16mm rod is highly susceptible to bending, so an external guide or pivot bracket is mandatory. This cylinder drifts under air loss, so add a rod lock for position holding. If an adjustable air cushion is needed, specify the MBLC variant.
Upgrade checklist
Yes, the MAL40X375SU is discontinued. The exact drop-in replacement is the MBL40X375SU, which matches the 40mm bore, 375mm stroke, 880N push force at 0.7MPa, G1/4 port, U flat-end cover, and mounting. The MBL upgrades the body to a riveted rolling-packed design and shifts sensors to the CMSG/DMSG/EMSG family.
The double-acting MAL40X375SU delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. It uses a fixed rubber bumper, not an adjustable cushion; for adjustable air cushioning, step up to the MBLC variant.
