This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50-CM-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50-CM-LB 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 MAL40X50-CM-LB (Discontinued) → MBL40X50-CM-LB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X50-CM-LB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-CM-LB is a discontinued double-acting aluminum mini round cylinder. It features a 40mm bore and 50mm stroke, delivering 628N push and 528N pull at 0.5MPa, and up to 880N push at 0.7MPa. The exact drop-in replacement is the MBL40X50-CM-LB, matching the bore, stroke, force, G1/4 port, and LB foot mounting. This legacy MAL unit uses threaded front and back covers, whereas the modern MBL upgrade features a riveted rolling-packed body for equally robust performance.
This specific SKU includes a CM round-end back cover and an LB foot mounting bracket for rigid base installation. It lacks a built-in magnet (-S), meaning it cannot accept a position sensor. The internal piston uses a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support the Ø16mm carbon-steel rod. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X50-CM-LB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X50-CM-LB 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.

Uses the 628N push force at 0.5MPa to deflect heavy wooden pallets onto a side spur track, where the LB foot mount holds the cylinder rigidly against the repeated lateral shock of impact.
Drives steel dowel pins into aluminum housings on an assembly line, leveraging the 880N push force at 0.7MPa to seat the pins fully without requiring a massive ISO 15552 profile cylinder.
Folds heavy corrugated cardboard flaps on a case sealer, where the CM round-end back cover allows slight angular alignment to the folding arm while the 50mm stroke cycles rapidly at up to 800mm/s.
To replace the MAL40X50-CM-LB, order the MBL40X50-CM-LB. Verify that your setup matches the G1/4 port, PT tapered thread, Ø16mm rod with an M12x1.25 end thread, CM round-end back cover, and LB foot mount. Because this SKU has no -S magnet, you cannot mount a sensor; if position detection is needed, switch to an MBL40X50S-CM-LB and upgrade to the modern CMSG, DMSG, or EMSG switch family (the older CS1-M/DS1-M sensors do not fit the new body). The fixed rubber bumper softens end-of-stroke impacts but is not a lock; the rod will drift if air pressure drops. For adjustable air cushioning, step up to the current MBLC line.
If you need to resize, step down to the 32mm bore (402N push at 0.5MPa) for lighter loads, or step up to the 50mm profile cylinder class for higher force. At 50mm stroke, side-load stress is minimal, but the 8-16mm rod diameter still means external guides are recommended for any off-axis loads.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X50-CM-LB. It matches the 40mm bore, 50mm stroke, 628N push force, G1/4 port, CM round-end back cover, and LB foot mount. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but drops right into the same application.
At 0.5MPa, the push force is 628N and pull is 528N. At 0.7MPa, push is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If you need sensing, order the MBL40X50S-CM-LB and use CMSG, DMSG, or EMSG switches.
