This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X450-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X450-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 MAL40X450-S-CA (Discontinued) → MBL40X450-S-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-S-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X450-S-CA is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. Operating at 0.5 MPa, it delivers 628 N of push force and 528 N of pull force, utilizing a G1/4 port and a Ø16 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced this legacy unit with the MBL40X450-S-CA, a drop-in alternative that matches the exact bore, stroke, force, port size, and CA pivot mounting for seamless integration.
This specific SKU includes a built-in magnet (-S) and a CA clevis back cover that pivots on a pin to absorb arcing loads. The legacy MAL relies on threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body. Furthermore, the -S magnet on this discontinued cylinder pairs with older CS1-M or DS1-M reed switches; upgrading to the MBL requires the current CMSG, DMSG, or EMSG sensor family. The MAL uses a fixed rubber bumper and a heterogeneous two-way grease-retaining seal.

The MBL40X450-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.

Swings a diverting arm on a packaging conveyor using the 628 N push force, while the CA pivot absorbs the arcing load as the 450 mm stroke extends.
Pushes a loaded tool tray out of an enclosure; the 880 N force at 0.7 MPa handles the mass, and the fixed rubber bumper softens the end of stroke.
Extends 450 mm to fold large carton flaps on a packing line, relying on the self-lubricating front-cover bearing guide to maintain smooth travel.
To replace the MAL40X450-S-CA, order the MBL40X450-S-CA, ensuring you retain the 40 mm bore, 450 mm stroke, G1/4 port, PT thread form, CA pivot back cover, and magnet. Because this SKU uses a -S magnet, you must swap your existing CS1-M or DS1-M switches for CMSG, DMSG, or EMSG sensors on the new MBL. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on the MAL, step up to the MBLC variant on the current line.
For sizing flexibility, you can step down to the 32 mm bore (providing 402 N push at 0.5 MPa) if your load is lighter, or step up to a larger profile cylinder if 628 N is insufficient. A plain MAL or MBL does not hold its position when air is lost, so add an external rod lock for suspended loads. Because the 450 mm stroke is long and the rod is only 16 mm, side-load tolerance is low; the CA pivot helps, but an external guide rail is recommended to prevent rod bending.
Upgrade checklist
Yes, the MAL40X450-S-CA is discontinued. The exact drop-in replacement is the MBL40X450-S-CA, which matches the 40 mm bore, 450 mm stroke, G1/4 port, and CA pivot mounting. The MBL body uses a riveted rolling-packed design instead of threaded covers, and you must upgrade your -S magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
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. The maximum theoretical force is 128 kgf at 1.0 MPa.
