This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X1150-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X1150-S-CA 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 MAL40X1150-S-CA (Discontinued) -> MBL40X1150-S-CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 1150mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X1150-S-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X1150-S-CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and a 1150mm non-standard stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X1150-S-CA, matching the original bore, stroke, force, port, and CA pivot mounting for seamless integration.
This legacy unit features a built-in magnet (-S) that pairs with older CS1-M or DS1-M switches, whereas the modern MBL replacement utilizes current CMSG, DMSG, or EMSG sensors. The older MAL body uses threaded front and back covers, while the upgraded MBL features a riveted rolling-packed body. A 1150mm stroke on a 16mm rod demands careful handling: the fixed rubber bumper only softens end-of-stroke impacts and provides no position holding if air pressure drops, so external guide rails and a pivot mount are essential to prevent rod bending.

The MBL40X1150-S-CA 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.

Drives the 1150mm stroke beater mechanism on a weaving loom, leveraging 628N of push force at 0.5MPa to pack weft threads tightly.
Extends a strapping head across a wide conveyor lane, using the CA pivot clevis to accommodate slight angular misalignment during the 1150mm travel.
Pushes heavy totes from a deep-shelf ASRS rack, relying on the 880N thrust at 0.7MPa to overcome carton friction over the long extension.
To replace the MAL40X1150-S-CA, order the MBL40X1150-S-CA. Verify your 40mm bore, 1150mm non-standard stroke, G1/4 port, and PT tapered thread. The CA back cover provides a pivot clevis that swings on a pin, which is critical for managing arcing loads across this long stroke. Because this SKU includes the -S magnet, remember that your legacy CS1-M or DS1-M switches will not fit the new body; you must upgrade to CMSG, DMSG, or EMSG sensors.
For sizing flexibility, stepping down to the 32mm bore yields 402N of push force at 0.5MPa, while stepping up is not an option as 40mm is the largest MAL/MBL mini round bore. At 1150mm, the 16mm carbon-steel rod with 20um hard chrome plating has low side-load tolerance, so an external guide is mandatory to prevent deflection. The MAL relies on a fixed rubber bumper; if your application requires an adjustable air cushion, step up to the MBLC variant on the current line. A plain cylinder drifts when air is lost, so add an external rod lock for strict position holding.
Upgrade checklist
Yes, the MAL40X1150-S-CA is discontinued. The exact drop-in replacement is the MBL40X1150-S-CA, which matches the 40mm bore, 1150mm stroke, CA pivot mounting, and G1/4 port. The MBL uses a riveted body instead of threaded covers, and you must upgrade your -S magnet sensors from the old CS1-M/DS1-M to the modern CMSG/DMSG/EMSG family.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it provides 880N push, with a maximum theoretical force of 128kgf at 1.0MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion; for adjustable cushioning, use the current MBLC line.
