This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X275CALB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X275CALB 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 MAL40X275CALB (Discontinued) -> MBL40X275CALB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 275mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X275CALB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X275CALB is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 275mm stroke. It delivers 628N of push force and 528N of pull force at 0.5MPa, peaking at 880N push at 0.7MPa. The exact drop-in replacement is the MBL40X275CALB, matching the bore, stroke, force, G1/4 port, and LB mounting footprint exactly.
This legacy SKU includes a CA pivot back cover designed to swing on a pin for arcing loads, paired with an LB foot bracket for base mounting. The original MAL body used threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for equal strength. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, working alongside a self-lubricating front-cover bearing guide.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X275CALB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X275CALB 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.

Actuates routing arms on conveyor lines, using the 880N push force at 0.7MPa to push heavy wooden pallets onto branch tracks.
Pushes raw steel bar stock through the spindle, where the CA pivot back cover absorbs slight misalignment during long 275mm extensions.
Folds heavy corrugated cardboard flaps on packaging machines, relying on the LB foot mount to stabilize the 628N push stroke at 0.5MPa.
To replace the MAL40X275CALB, order the MBL40X275CALB. Verify your setup accommodates the G1/4 port, PT tapered thread, 16mm rod with an M12x1.25 end thread, the CA clevis back cover, and the LB foot mounting bracket. If your machine requires end-of-stroke cushioning, note that the MAL uses a fixed rubber bumper; for an adjustable air cushion, step up to the current MBLC line.
For sizing flexibility, stepping down to the 32mm bore neighbor yields 402N push at 0.5MPa, while stepping up is not possible as 40mm is the largest in this mini series. Because this 275mm stroke exceeds 300mm limits, the 16mm rod is susceptible to bending under side loads—always use an external guide or rely on the CA pivot to absorb radial stress. A plain cylinder drifts when air is lost, so add an external rod lock for position holding.
Upgrade checklist
Yes, the MAL40X275CALB is discontinued. The exact drop-in replacement is the MBL40X275CALB, which matches the 40mm bore, 275mm stroke, G1/4 port, CA pivot cover, and LB foot mount. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but maintains identical performance.
The 40mm bore generates 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; the -S versions use CS1-M/DS1-M switches, while the MBL replacement uses CMSG/DMSG/EMSG sensors.
