This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X120SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X120SU 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 MAL40X120SU (Discontinued) -> MBL40X120SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 120mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X120SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X120SU is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 120mm stroke. It delivers 628N push and 528N pull at 0.5MPa, peaking at 880N push at 0.7MPa. The exact drop-in replacement is the MBL40X120SU, matching the bore, stroke, 128kgf max force, G1/4 port, and U flat-end back cover for a seamless retrofit.
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 reed switches, whereas the MBL successor uses the current CMSG, DMSG, or EMSG sensor families. The original MAL features threaded front and back covers on the barrel, while the MBL upgrade utilizes a riveted rolling-packed body. Both share a fixed rubber bumper and a carbon-steel rod with 20um hard chrome plating, guided by a self-lubricating bearing.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X120SU 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 MBL40X120SU 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 628N of push at 0.5MPa to eject small plastic parts from tight mold cavities, utilizing the 120mm stroke to clear the mold base entirely before robotic pickup.
Shifts lightweight routing gates on a packaging conveyor, where the 528N pull force at 0.5MPa reliably retracts the 16mm hard-chrome rod against the friction of sliding guide rails.
Folds top flaps on small product cartons, where the U flat-end back cover mounts rigidly to the machine frame and the fixed rubber bumper absorbs the 120mm stroke impact without damaging the packaging.
To replace the MAL40X120SU, order the MBL40X120SU, ensuring you keep the 40mm bore, 120mm stroke, G1/4 port, PT thread, U flat-end back cover, and the -S magnet. Because the -S magnet is present, plan to upgrade your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG switches used on the MBL platform. The fixed rubber bumper softens end-of-stroke impact but is not an adjustable cushion; if your application needs precise end-of-stroke deceleration, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to a larger profile cylinder provides higher force. At 120mm stroke, side-load tolerance is moderate; the 16mm rod handles standard loads, but a U flat-end cover requires rigid alignment. A plain bumper does not hold the load if air pressure drops, so add an external rod lock or pilot-operated check valve for fail-safe position holding.
Upgrade checklist
Yes, the MAL40X120SU is discontinued. The exact drop-in replacement is the MBL40X120SU, which matches the 40mm bore, 120mm stroke, 128kgf max force, G1/4 port, and U flat-end mounting. The main upgrade is the body construction: the MAL uses threaded covers, while the MBL uses a riveted rolling-packed body.
The 40mm bore generates 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128kgf at 1.0MPa. Because this SKU includes the -S magnet, it works with older CS1-M or DS1-M switches; the MBL replacement requires upgrading to CMSG, DMSG, or EMSG sensors.
