This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X185SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X185SU 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 MAL40X185SU (Discontinued) → MBL40X185SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 185mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X185SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X185SU is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 185mm 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 MBL40X185SU, which matches the original bore, stroke, output force, port size, and flat-end U back cover for a seamless swap.
A key upgrade detail is that the legacy MAL uses threaded front and back covers on the barrel, whereas the modern MBL features a riveted rolling-packed body. Additionally, this SKU includes a built-in magnet (-S) for position sensing; the older MAL works with CS1-M or DS1-M switches, while the MBL replacement requires the current CMSG, DMSG, or EMSG sensor family. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20 um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X185SU 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 MBL40X185SU 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 628 N of push force at 0.5 MPa to eject small plastic parts from mold cavities, with the 185mm stroke reaching deep into the tooling.
Delivers 528 N of pull force to retract a routing flap on a packaging conveyor, ensuring parcels are sorted accurately at high speeds.
Acts as a rigid stop for lightweight assembly pallets using the flat-end U cover, absorbing impact with its fixed rubber bumper at the end of the 185mm stroke.
To replace the MAL40X185SU, order the MBL40X185SU and confirm the 40mm bore, 185mm stroke, G1/4 port, and U flat-end back cover. Because this SKU includes the -S magnet, you must upgrade your sensors from the legacy CS1-M/DS1-M to the modern CMSG/DMSG/EMSG switches. If your cycle produces heavy end-impact, note that the MAL relies on a fixed rubber bumper; for an adjustable air cushion, step up to the MBLC series.
For sizing flexibility, stepping down to the 32mm bore yields 402 N push at 0.5 MPa, while stepping up is not an option within this mini series as 40mm is the largest available bore. At 185mm stroke, the 16mm rod handles moderate loads, but a plain cylinder does not hold its position when air is lost—the rod drifts, so use an external rod lock or pilot-operated check valve for safety. The U flat-end cover provides a rigid rear mount, which is ideal when the chassis provides precise alignment.
Upgrade checklist
Yes, the MAL40X185SU is discontinued. The exact drop-in replacement is the MBL40X185SU, which offers the same 40mm bore, 185mm stroke, 880 N push force at 0.7 MPa, G1/4 port, and flat-end U back cover.
At 0.5 MPa it delivers 628 N push and 528 N pull, reaching 880 N push at 0.7 MPa with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this model includes the -S magnet, it works with older CS1-M/DS1-M switches, but the MBL replacement requires CMSG/DMSG/EMSG sensors.
