This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X20CAH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X20CAH 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 MAL40X20CAH (Discontinued) -> MBL40X20CAH is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 20mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X20CAH, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X20CAH is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces requiring high thrust. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force, scaling to a maximum theoretical output of 128 kgf at 1.0 MPa. Because this legacy series has reached end-of-life, AirTAC mandates the MBL40X20CAH as the direct drop-in replacement. It matches the original 40 mm bore, 20 mm stroke, G1/4 port size, and CA pivot mounting exactly, ensuring a seamless retrofit without altering your existing pin or bracket geometry.
This specific SKU features a CA clevis back cover that swings on a pin to absorb arcing loads, distinguishing it from rigid flat-end U or round-end CM covers. Internally, the MAL uses a heterogeneous two-way seal that retains grease, riding on a hard-chrome plated carbon-steel rod. The original MAL body relies on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Note that this unit lacks a magnet (-S), so it cannot accept CS1-M or DS1-M position sensors.

The MBL40X20CAH 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.

Short 20 mm stroke delivers 880 N of push force at 0.7 MPa to kick small metal blanks out of a progressive stamping die.
The CA pivot clevis accommodates arcing mechanical motion as the 40 mm rod actuates a routing flap on a packaging conveyor line.
High 628 N thrust at 0.5 MPa firmly tucks heavy corrugated cardboard flaps during automated case erecting machinery cycles.
To replace the discontinued MAL40X20CAH, order the MBL40X20CAH. Confirm your pivot pin matches the CA back cover and that your air line utilizes the G1/4 port. Because this SKU lacks the -S magnet, it cannot support position sensing; if you require rod detection on the new unit, specify an MBL40X20CAHS and upgrade to the current CMSG, DMSG, or EMSG sensor family. The fixed rubber bumper on this cylinder softens end-of-stroke impact but is not an adjustable cushion; for decelerating heavier loads, step up to the MBLC series which offers adjustable air cushions.
When sizing this 40 mm bore actuator, evaluate your force requirements carefully. If 628 N of push at 0.5 MPa is excessive, step down to the 32 mm bore variant, which supplies 402 N of push force. Conversely, if you need more power, 40 mm is the largest available MAL mini round body, so exceeding 128 kgf theoretical output requires migrating to a different cylinder family entirely. Remember that a plain double-acting cylinder does not hold its position if air pressure drops; add a pilot-operated check valve or external rod lock for suspended load safety.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X20CAH, which matches the 40 mm bore, 20 mm stroke, G1/4 port, and CA pivot mounting. The modern MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. This unit has no magnet, so it cannot use CS1-M or DS1-M sensors.
