This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X20SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X20SCA 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 MAL40X20SCA (Discontinued) → MBL40X20SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 20mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X20SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X20SCA is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. As the largest bore in the MAL family, it delivers a robust 628 N push force at 0.5 MPa (880 N at 0.7 MPa) over a short 20 mm stroke. AirTAC replaced this legacy unit with the MBL40X20SCA, a drop-in alternative that matches the exact bore, stroke, force, G1/4 port, and CA pivot mounting.
This legacy SKU features a built-in magnet (-S) and a CA pivot back cover designed to absorb arcing loads. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. If your application requires end-of-stroke deceleration, note that this cylinder relies on a fixed rubber bumper rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X20SCA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X20SCA 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 628 N push force at 0.5 MPa to knock small metal stampings out of a die, with the CA pivot absorbing the slight angular misalignment of the ejection arm.
Swings a lightweight routing gate on a packaging conveyor, where the short 20 mm stroke provides rapid actuation without extending into the walkway.
Deploys a heavy-duty stop pin to halt 40 mm pallets on an assembly line, relying on the 128 kgf maximum theoretical holding capability against forward momentum.
To replace the MAL40X20SCA, order the MBL40X20SCA. Verify your setup accommodates the G1/4 port and M12x1.25 rod-end thread. Because this SKU includes the -S magnet, you must update your sensing electronics: the older CS1-M and DS1-M switches are retired alongside the MAL, so migrate to the current CMSG, DMSG, or EMSG sensor family for the MBL.
When sizing, step down to a 32 mm bore if you need less force (it provides 402 N push at 0.5 MPa). If you need to scale up, note that 40 mm is the maximum diameter available in this mini round series. The 16 mm carbon-steel rod with 20 um hard-chrome plating offers minimal side-load tolerance on this short 20 mm stroke; for any drifting or suspended loads, add an external rod lock, as the rubber bumper only softens impact and will not hold position.
Upgrade checklist
Yes, the MAL40X20SCA is discontinued. The exact drop-in replacement is the AirTAC MBL40X20SCA, which matches the 40 mm bore, 20 mm stroke, G1/4 port, and CA pivot mount. You must upgrade your sensors from the old CS1-M / DS1-M to the modern CMSG / DMSG / EMSG switches.
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 operating pressure.
