This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X300ULB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X300ULB 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 MAL40X300ULB (Legacy) → MBL40X300ULB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X300ULB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300ULB is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 300mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. AirTAC replaced this legacy series with the MBL40X300ULB, a true drop-in alternative retaining the exact same bore, stroke, output force, port size, and LB foot mounting pattern for seamless integration.
This specific SKU features a U flat-end back cover for rigid rear mounting and an LB foot bracket. Because it lacks the -S magnet option, this cylinder cannot accept a position sensor. The original MAL body used threaded front and back covers, whereas the modern MBL upgrade features a riveted rolling-packed body. Both designs rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X300ULB 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 MBL40X300ULB 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.

Pushes medium-weight product pallets off a main conveyor line, utilizing the 628N push force at 0.5MPa to overcome sliding friction over a 300mm diversion gap.
Actuates folding arms on a packaging line to tuck top flaps prior to tape sealing, relying on the rigid LB foot mount and U flat-end back cover to maintain bracket alignment.
Raises and lowers a light-duty CNC router spindle head through a 300mm travel range, using the G1/4 port for rapid double-acting actuation during tool changes.
To replace the discontinued MAL40X300ULB, order the MBL40X300ULB. Confirm your 40mm bore, 300mm stroke, G1/4 port, PT thread, U flat-end back cover, and LB foot mounting accessory all match the new unit. If your application requires adjustable end-cushioning to absorb heavy kinetic energy, step up to the current MBLC40X300ULB variant, as the standard MAL only provides a fixed rubber bumper. If you need position sensing, note that this specific legacy SKU lacks a magnet and cannot hold a sensor; an MBL equivalent with the -S suffix is required, which also shifts the compatible switch family from the older CS1-M / DS1-M to the modern CMSG / DMSG / EMSG series.
For sizing flexibility, you can step down to the 32mm bore neighbor (providing 402N push at 0.5MPa) if your load is lighter, or step up to a larger profile cylinder if 628N is insufficient. A plain MAL or MBL cylinder does not hold its load when air pressure is lost; the rod will drift, so an external rod lock or pilot-operated check valve is required for vertical safety. Furthermore, driving a 300mm stroke with the 16mm rod demands careful alignment; the fixed U flat-end cover offers no angular forgiveness, so use external guides or pivot mounts to prevent rod bending under side loads.
Upgrade checklist
Yes, the MAL40X300ULB is discontinued. The exact drop-in replacement is the MBL40X300ULB, which matches the 40mm bore, 300mm stroke, G1/4 port, and LB foot mount. The new MBL uses a riveted rolling-packed body instead of the older threaded covers, but maintains the same force ratings and mounting footprint.
The 40mm bore generates a push force of 628N and a pull force of 528N at 0.5MPa. At 0.7MPa, the push force increases to 880N. The maximum theoretical force is 128kgf at 1.0MPa. Note that this specific SKU lacks a magnet, so it cannot support position sensors.
