This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X640SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X640SCA 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 MAL40X640SCA (Discontinued) → MBL40X640SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 640mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X640SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X640SCA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and a 640mm stroke. Because 640mm exceeds the 500mm standard maximum, this is a made-to-order unit. It delivers a robust 628 N push force at 0.5 MPa. The exact drop-in replacement is the MBL40X640SCA, which matches the bore, stroke, force, G1/4 port, and CA pivot mount. You simply order the MBL equivalent.
This legacy SKU includes a built-in magnet (-S) for position detection and a CA pivot back cover that swings on a pin to absorb arcing loads. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Additionally, the -S magnet on this MAL works with the older CS1-M and DS1-M switches, but upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor family.

The MBL40X640SCA 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.

Drives the up-and-down shedding motion of heddle frames in wide weaving looms, utilizing the 628 N push force at 0.5 MPa and the CA pivot mount to handle the slight arcing deflection of the 640mm stroke.
Pushes heavy wooden pallets onto a branching gravity roller conveyor, where the 880 N push force at 0.7 MPa easily overcomes sliding friction across the 640mm travel distance.
Sweeps filled corrugated cartons from a high-speed packaging belt into a sorting chute, relying on the -S magnet and CS1-M sensors to confirm full extension before the conveyor advances.
To replace this MAL, order the MBL40X640SCA. Confirm your 640mm stroke requirement, as it is a non-standard length exceeding the 500mm standard limit. The G1/4 port and M12x1.25 rod-end thread remain identical. The CA pivot back cover is essential for this long 640mm stroke, as it accommodates arcing rod movements. If you need to step down, the 32mm bore neighbor provides 402 N push at 0.5 MPa; if you need more force, you are at the largest MAL size and must look outside this mini round series.
Because the stroke is 640mm, the 16mm carbon-steel rod is highly susceptible to bending under side loads—use an external guide rail to prevent premature seal wear. The fixed rubber bumper only softens end-of-stroke impacts and does not lock the rod; if air pressure drops, the load will drift, requiring an external pilot-operated check valve for position holding. If your application requires adjustable end-cushioning for heavy moving masses, step up to the MBLC variant on the current line, as neither the MAL nor standard MBL offers this feature.
Upgrade checklist
Yes, the MAL40X640SCA is discontinued. The exact drop-in replacement is the MBL40X640SCA, which offers the same 40mm bore, 640mm stroke, G1/4 port, and CA pivot mount. The MBL upgrades the body to a riveted rolling-packed structure, and you must update your position sensors from the older CS1-M or DS1-M to the current CMSG, DMSG, or EMSG family.
The double-acting MAL40X640SCA generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption, which is not an adjustable air cushion. If adjustable cushioning is required, you must use the MBLC variant on the current line.
