This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X550-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X550-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 MAL40X550-S-CA (Discontinued) -> MBL40X550-S-CA 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 MBL40X550-S-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X550-S-CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 550mm stroke. Because 550mm exceeds the 500mm standard maximum, this specific length was a made-to-order configuration. It delivers 628N of push force and 528N of 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 MBL40X550-S-CA, which matches the bore, stroke, force, port, and CA pivot mounting exactly.
This legacy unit features a built-in magnet (-S) for position detection and a CA pivot clevis back cover designed to accommodate arcing side-loads. The older MAL body used threaded front and back covers on the barrel, whereas the current MBL replacement utilizes a riveted rolling-packed body construction. Additionally, the -S magnet on this discontinued model functions with the older CS1-M and DS1-M reed switches; upgrading to the MBL requires transitioning to the current CMSG, DMSG, or EMSG sensor families.

The MBL40X550-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.

Pushes and pivots a light welding head along a 550mm path. The CA clevis accommodates the slight arcing geometry, while the 628N thrust at 0.5 MPa easily overcomes guide friction.
Extends a sorting flap across a narrow conveyor belt. The 880N push force at 0.7 MPa ensures positive actuation, while the 40mm bore fits within tight transfer side-frames.
Strokes 550mm to push empty trays out of a vertical magazine. The built-in magnet (-S) confirms full extension before the lift mechanism lowers.
To replace the MAL40X550-S-CA, order the MBL40X550-S-CA. Confirm your exact requirements before ordering: the 550mm stroke is non-standard and made-to-order, the port is G1/4, and the thread form is PT (tapered). You must also specify the CA pivot back cover for arcing loads and the -S magnet. Because the -S magnet on the MAL works with CS1-M/DS1-M switches, you will need to update to CMSG/DMSG/EMSG sensors for the MBL replacement. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the MBLC series on the current line.
When sizing, step down to the 32mm bore (402N push at 0.5 MPa) if you need less force, or step up to the 50mm profile cylinder if you need more. At 550mm, the 16mm rod is highly susceptible to bending under side-loads; always use an external guide rail alongside the CA pivot. A plain cylinder does not hold its position when air is lost—the rod drifts and the bumper only softens the end of stroke, so add an external rod lock or pilot-operated check valve for fail-safe load holding.
Upgrade checklist
Yes, the MAL40X550-S-CA is discontinued. The exact drop-in replacement is the MBL40X550-S-CA, which provides the same 40mm bore, 550mm stroke, 628N push force at 0.5 MPa, G1/4 port, and CA pivot mounting. The MBL upgrades the body to a riveted rolling-packed design and requires CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The 40mm bore provides 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum theoretical force of 128kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion. If adjustable cushioning is needed, use the current MBLC series.
