This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X165SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X165SU 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 MAL40X165SU (Discontinued) -> MBL40X165SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 165mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X165SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X165SU is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 165mm stroke. It delivers a robust 628 N push force at 0.5 MPa, utilizing a G1/4 port and a 16mm carbon-steel rod with a 20 um hard-chrome plating. The SKU includes a U flat-end back cover for rigid mounting and a built-in magnet (-S) for position detection.
AirTAC replaced this legacy unit with the MBL40X165SU, a true drop-in alternative matching the exact bore, stroke, output force, port size, and mounting interface. A key upgrade is the body construction: the MAL uses threaded front and back covers, whereas the MBL features a riveted rolling-packed body. Furthermore, the -S magnet on the MAL functions with the older CS1-M and DS1-M switches, while the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X165SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X165SU 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.

Halts 128 kgf pallet traffic on a packaging line using the 880 N push force at 0.7 MPa, leveraging the rigid U flat-end rear to absorb repeated end-of-stroke impacts.
Slides a heavy machine tool safety door open and closed across the 165mm stroke, relying on the 16mm hard-chrome plated carbon-steel rod for smooth, debris-resistant travel.
Folds large corrugated box flaps in an end-of-line packer, where the self-lubricating front-cover bearing guide ensures consistent motion without external grease maintenance.
To replace the MAL40X165SU, order the MBL40X165SU and verify the 40mm bore, 165mm stroke, G1/4 port, and PT thread form. Confirm the U flat-end back cover for your rigid rear setup, and note that your -S magnet requires upgrading from CS1-M/DS1-M to CMSG/DMSG/EMSG switches on the new MBL. If your application needs an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the MBLC variant on the current line. Keep in mind a plain MBL will not hold a load if air pressure drops; utilize an external rod lock for fail-safe positioning.
For sizing flexibility, stepping down to the 32mm bore yields 402 N of push force at 0.5 MPa, while stepping up is not an option as 40mm is the largest mini round bore available. At 165mm stroke, the 16mm rod is susceptible to bending under lateral stress; pair it with an external guide rail to prevent premature seal wear.
Upgrade checklist
Yes, the MAL40X165SU is discontinued. The exact drop-in replacement is the MBL40X165SU, which matches the 40mm bore, 165mm stroke, G1/4 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design and changes the sensor compatibility from CS1-M/DS1-M to CMSG/DMSG/EMSG switches.
At 0.5 MPa, the 40mm bore provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force reaches 880 N. The cylinder operates safely up to 1.0 MPa, yielding a theoretical maximum force of 128 kgf.
