This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X1250SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X1250SCA 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 MAL40X1250SCA (Discontinued) -> MBL40X1250SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 1250mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X1250SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X1250SCA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and a 1250mm stroke. Because 1250mm exceeds the 500mm standard limit, this unit was a special made-to-order configuration delivering 628 N push force at 0.5 MPa. It features a built-in magnet (-S) for position sensing and a CA pivot clevis back cover. AirTAC replaced the legacy MAL line with the MBL series, making the MBL40X1250SCA your exact drop-in replacement, matching the bore, stroke, output force, G1/4 port and mounting hardware.
Two structural details matter for your migration. First, the original MAL body uses threaded front and back covers, while the current MBL uses a riveted rolling-packed body for greater structural integrity under long-stroke stress. Second, the -S magnet on this legacy cylinder interfaces with the older CS1-M and DS1-M reed switches; upgrading to the MBL40X1250SCA requires the modern CMSG, DMSG or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X1250SCA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 128 kgf | |
The MBL40X1250SCA 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 width-adjustment tenter frame arms in a textile loom. The 628 N push force at 0.5 MPa easily overcomes fabric tension, while the CA pivot bracket accommodates the frame's slight angular shift over the 1250mm travel.
Pushes empty pallets from a high-speed packaging conveyor onto a diverter chain. The 880 N force at 0.7 MPa pushes heavy wooden pallets reliably, but an external guide rail is mandatory to prevent the 16mm rod from bending over the long stroke.
Raises loaded composite trays in a compact vertical lift station. The 1250mm stroke reaches the second-tier shelf, and the built-in -S magnet triggers a DS1-M reed switch to confirm the tray is fully stowed before the lift retracts.
To replace the MAL40X1250SCA, order the MBL40X1250SCA and confirm the PT tapered port thread, the CA pivot back cover, and the -S magnet configuration. The CA clevis mount is essential here because a 1250mm stroke creates severe side-load and rod-bending risks; the pivot allows the cylinder body to swing on a pin, absorbing arcing misalignment. You must use an external guide rail to support the load, as the 16mm carbon-steel rod alone cannot withstand lateral forces over 1.25 meters. If you need to adjust sizing, stepping down to the 32mm bore yields 402 N push at 0.5 MPa, while no larger mini-round bore exists in this family. Note that the fixed rubber bumper only softens end-of-stroke impacts and does not lock the load; if air is lost, the rod drifts, so add an external pilot-operated check valve for position holding. If your application needs adjustable end-cushioning to stop a heavy load, step up to the MBLC variant on the current line, as the MAL lacks this feature.
Upgrade checklist
Yes, the MAL40X1250SCA is discontinued. The exact drop-in replacement is the MBL40X1250SCA, which matches the 40mm bore, 1250mm stroke, 628 N force, G1/4 port, CA pivot mount and -S magnet. You only need to swap the older CS1-M or DS1-M sensors for the current CMSG, DMSG or EMSG switch family.
The 40mm bore 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 G1/4 port, a 16mm carbon-steel rod with M12x1.25 thread, operates at 0.1-1.0 MPa, and runs at 30-800 mm/s. The 1250mm stroke is non-standard and requires external side-load guidance.
