This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X550CMLB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X550CMLB 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 MAL40X550CMLB (Discontinued) -> MBL40X550CMLB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 550mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X550CMLB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X550CMLB is a discontinued double-acting compact aluminum mini round cylinder with a 40mm bore and 550mm stroke. As a non-standard made-to-order stroke exceeding the 500mm maximum, it delivers a robust 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBL40X550CMLB, which matches the force, G1/4 port, and LB foot mounting exactly.
This legacy unit features a CM round-end back cover paired with an LB foot mounting bracket. Because this specific SKU lacks the -S magnet option, it cannot accept any position sensor. The original MAL body used threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body for equally durable performance. If adjustable cushioning is required for this heavy 128kgf class, the current MBLC line offers that feature, whereas the MAL only provides a fixed rubber bumper.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X550CMLB 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 MBL40X550CMLB 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.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Provides 628N of push force at 0.5MPa to eject plastic parts from tight mold spaces, utilizing the 550mm stroke to clear deep mold cavities safely.
Drives a heavy diverter arm on a packaging line, where the LB foot mount and CM round-end back cover handle the arcing pivot motion required to redirect pallets.
Executes long-reach folding of large corrugated carton flaps, relying on the 880N push force at 0.7MPa to overcome cardboard springback during case erecting.
To replace the MAL40X550CMLB, order the MBL40X550CMLB, ensuring you keep the CM round-end back cover, LB foot mounting, and PT tapered thread. Since this SKU has no -S magnet, you cannot mount a CS1-M or DS1-M sensor; if you now require position detection, specify an MBL with the -S option to use the current CMSG/DMSG/EMSG switches. If you need to step down, the 32mm bore offers 402N push at 0.5MPa; if stepping up, note that 40mm is the largest available bore in this mini series. The 550mm stroke on this 16mm rod demands strict side-load management—use an external guide rail to prevent rod bending, as the fixed rubber bumper only softens end-of-stroke impact and provides no load-holding capability when air is lost. For those needing end-of-stroke deceleration control rather than a simple bumper, the MBLC variant provides an adjustable air cushion.
Upgrade checklist
Yes, the MAL40X550CMLB is discontinued. The exact drop-in replacement is the MBL40X550CMLB, which matches the 40mm bore, 550mm stroke, G1/4 port, and LB foot mount. The MBL uses a riveted rolling-packed body instead of the original threaded covers, and if you need an adjustable cushion, look at the MBLC variant.
At 0.5MPa, the push force is 628N and the pull force is 528N. At 0.7MPa, the push force is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept position sensors; the MBL replacement with -S uses CMSG/DMSG/EMSG switches.
