This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X150CALB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X150CALB 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 MAL40X150CALB (Discontinued) -> MBL40X150CALB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 150mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X150CALB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X150CALB is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 150mm stroke. It delivers a robust 628N push and 528N pull force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X150CALB, which matches the original bore, stroke, output force, port size, and LB foot mounting.
This legacy SKU features a CA pivot back cover that swings on a pin to absorb arcing rod loads, paired with an LB foot bracket for rigid base mounting. The original MAL body uses threaded front and back covers, whereas the modern MBL upgrade features a riveted rolling-packed body. Because this specific configuration lacks the -S magnet, it cannot accept a position sensor.
The MAL relies on a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable cushion. If your equipment requires precise end-of-stroke deceleration, step up to the current MBLC variant which offers adjustable air cushioning. The carbon-steel rod is protected by 20μm hard-chrome plating and guided by a self-lubricating bearing. Note that a plain cylinder does not hold its load when air pressure is lost; the rod will drift, so a separate pilot-operated check valve is required for position holding.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X150CALB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X150CALB 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 pallets onto a side spur track, where the CA pivot back cover absorbs the arcing load during the deflection arc.
Extends 150mm to fold heavy corrugated cardboard flaps on a case erector, relying on the LB foot mount to hold the cylinder rigidly against the machine frame.
Pushes a mold safety gate open with 880N at 0.7MPa, where the fixed rubber bumper provides adequate end-of-stroke damping for this short, repetitive motion.
To replace the MAL40X150CALB, order the MBL40X150CALB to retain the exact 40mm bore, 150mm stroke, G1/4 port, PT thread, CA pivot back cover, and LB foot mount. If you need to adjust the force, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the 50mm bore (available in the broader MBL line) provides higher thrust. Because this SKU has no -S magnet, it cannot support a sensor; if you need position detection, order the MBL40X150CAS and note that the modern MBL uses CMSG, DMSG, or EMSG switches rather than the legacy CS1-M/DS1-M family.
At 150mm stroke, the 16mm rod handles standard loads, but for any stroke of 300mm or more, you must manage side-load and rod bending by using the CA pivot, adding an external guide, or switching to a double-rod MBLD. Remember that the fixed rubber bumper is not a lock; if gravity or air-loss makes the load drift, install an external rod lock.
Upgrade checklist
Yes, the MAL40X150CALB is discontinued. The exact drop-in replacement is the MBL40X150CALB, which matches the 40mm bore, 150mm stroke, G1/4 port, CA pivot back cover, and LB foot mount. The modern MBL uses a riveted rolling-packed body instead of the older threaded covers, but all performance ratings remain identical.
At 0.5MPa it provides 628N push and 528N pull force, increasing to 880N push at 0.7MPa, with a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; the MBL40X150CAS variant is required for CMSG/DMSG/EMSG switch integration.
