This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X300-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X300-CM 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 MAL40X300-CM (Discontinued) -> MBL40X300-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X300-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300-CM is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 300mm stroke. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X300-CM, which matches the original bore, stroke, output force, port size, and CM round-end back cover for a seamless upgrade.
This legacy unit utilizes a carbon-steel rod with 20 um hard chrome plating and a heterogeneous two-way seal that retains grease, supported by a self-lubricating front-cover bearing guide. The original MAL body uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Note that this specific SKU lacks a built-in magnet, meaning it cannot support position sensing.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X300-CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X300-CM 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 628 N push force at 0.5 MPa to deflect heavy pallets onto a side branch, fitting within tight machinery frames.
The 300mm stroke reaches deep into a magazine to push the bottom box out of a vertical stack during packaging operations.
Cycles long raw material bars out of the spindle tube, relying on the 40mm bore's 128 kgf max force to overcome friction.
To replace the MAL40X300-CM, order the MBL40X300-CM, ensuring you retain the PT port thread, G1/4 port size, and CM round-end back cover. If you need to step down, the 32mm bore neighbor provides 402 N push at 0.5 MPa; if you need more force, 40mm is the largest available MAL mini round size, so stepping up further requires migrating to a different ISO 15552 profile cylinder family. Because this SKU has no -S magnet, it cannot accept a CS1-M or DS1-M sensor, and the MBL equivalent will similarly lack sensing capabilities unless you add the -S option (which changes the sensor family to CMSG / DMSG / EMSG).
With a 300mm stroke on a 16mm rod, side-load tolerance is low; an external guide rail or pivot mounting is strongly recommended to prevent rod bending. The MAL uses a fixed rubber bumper, not an adjustable cushion—if you need end-of-stroke deceleration for a heavy load, step up to the MBLC variant on the current line. A plain MBL does not hold its position when air is lost, so add an external rod lock or pilot-operated check valve for suspended loads.
Upgrade checklist
Yes, the MAL40X300-CM is discontinued. The exact drop-in replacement is the MBL40X300-CM, which matches the 40mm bore, 300mm stroke, 628 N push force, G1/4 port, and CM round-end back cover. The MBL upgrades the body to a riveted rolling-packed design instead of the original 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 is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot support position sensors; if you order an MBL with -S, it uses the newer CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M.
