This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X450-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X450-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 MAL40X450-CA (Discontinued) -> MBL40X450-CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 450mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X450-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X450-CA is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the legacy range, it delivers a push force of 628 N at 0.5 MPa (880 N at 0.7 MPa) across a 450 mm stroke. AirTAC replaced this unit with the MBL40X450-CA, a drop-in alternative retaining the exact 40 mm bore, G1/4 port, and CA clevis mounting. This SKU lacks a magnet, so it cannot accept a position sensor.
Two structural details distinguish the old from the new. The MAL body uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body for structural rigidity. Additionally, the MAL relies on a fixed rubber bumper to soften end-of-stroke impacts; if your application requires adjustable air cushioning, you must step up to the current MBLC line rather than seeking an adjustable MAL.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X450-CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X450-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.

Uses the 880 N push force at 0.7 MPa to knock stamped metal blanks out of a die, relying on the 450 mm stroke to clear the press bed entirely.
Extends a sweeping arm to redirect heavy pallets on a packaging line, where the CA pivot bracket accommodates the geometric arc of the shifting load.
Raises a heavy guard panel on a CNC machine, taking advantage of the 628 N pull force at 0.5 MPa to retract the 450 mm stroke safely out of the work zone.
To replace this MAL, order the MBL40X450-CA, confirming the 40 mm bore, 450 mm stroke, PT thread, and CA pivot back cover are retained. Because this is a non-magnet SKU, it cannot support a CS1-M or DS1-M sensor; if you need position detection, specify an MBL40X450S-CA and migrate to the modern CMSG/DMSG/EMSG switch family. If you need to adjust force, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while no larger bore exists in this mini series. A plain cylinder does not hold its load when air is lost—the rod drifts—so use an external rod lock for suspended loads.
At 450 mm of stroke, the 16 mm carbon-steel rod is highly susceptible to bending under lateral stress. The CA pivot back cover is explicitly designed for this, allowing the cylinder body to swing on a pin and absorb arcing loads. Even with the pivot, you should use an external guide rail to support the tooling and prevent side-load wear on the self-lubricating front-cover bearing.
Upgrade checklist
Yes, the MAL40X450-CA is discontinued. The exact drop-in replacement is the MBL40X450-CA, which matches the 40 mm bore, 450 mm stroke, G1/4 port, and CA pivot mounting. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but the performance ratings are identical.
The 40 mm bore provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. Note that this specific SKU has no magnet and cannot support a position sensor.
