This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X115SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X115SU 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 MAL40X115SU (Discontinued) → MBL40X115SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 115mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X115SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X115SU is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 115mm stroke. It delivers 628N push and 528N pull at 0.5MPa, making it the highest force class in this compact series. The exact drop-in replacement is the MBL40X115SU, matching the bore, stroke, G1/4 port, and U flat-end back cover exactly.
This legacy SKU includes a built-in magnet (-S) for position detection. On the MAL, this magnet pairs with the older CS1-M or DS1-M switches, whereas the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. The original MAL body uses threaded front and back covers, while the upgraded MBL features a riveted rolling-packed body for equally robust performance. Both generations use a fixed rubber bumper rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X115SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X115SU 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 the ejection plate on a 50-ton injection molding machine, using the 115mm stroke to clear the tooling and 628N push force to break small plastic parts free.
Actuates a heavy pneumatic diverter gate on a packaging conveyor, where the 40mm bore provides the 528N pull force needed to retract the heavy steel flap against friction.
Performs the final fold-and-press action on a case erector, relying on the 880N force at 0.7MPa to seal heavy corrugated flaps securely.
To replace the MAL40X115SU, order the MBL40X115SU. Confirm the 40mm bore, 115mm stroke, G1/4 port, PT thread form, and the U flat-end back cover. Because this SKU includes an -S magnet, you must update your position sensing: the legacy CS1-M and DS1-M switches are retired, so select CMSG, DMSG, or EMSG sensors for the MBL. If your application requires an adjustable air cushion rather than the fixed rubber bumper, step up to the MBLC variant on the current line.
For sizing flexibility, you can step down to the 32mm bore neighbor (providing 402N push at 0.5MPa) to save space, or step up to the 50mm profile cylinder class for higher force. Remember that a plain MAL or MBL does not hold a load when air pressure is lost; the rod will drift. For safety against dropping loads, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X115SU is discontinued. The exact drop-in replacement is the MBL40X115SU, which matches the 40mm bore, 115mm stroke, G1/4 port, U flat-end back cover, and S magnet. The MBL uses a riveted rolling-packed body instead of threaded covers, and its magnet requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches.
The 40mm bore provides 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 for end-of-stroke damping, not an adjustable cushion. If you need adjustable air cushioning, order the current-line MBLC variant.
