This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X20SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X20SCM 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 MAL40X20SCM (Discontinued) -> MBL40X20SCM 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 MBL40X20SCM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X20SCM is a discontinued double-acting aluminum mini round cylinder. As a legacy 40mm bore unit, it delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and a 16mm carbon-steel rod with 20um hard chrome plating. The exact drop-in replacement is the MBL40X20SCM, matching the bore, stroke, output force, port size, and CM round-end back cover for a seamless transition.
This specific SKU includes a built-in magnet (-S) for position sensing. On the legacy MAL, this magnet interfaces with older CS1-M or DS1-M reed switches, whereas the modern MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. Additionally, the original MAL features threaded front and back covers, while the upgraded MBL utilizes a riveted rolling-packed body. Both designs rely on a fixed rubber bumper, meaning the rod will drift if air pressure is lost.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X20SCM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X20SCM 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.

Provides 628N of push force at 0.5MPa to eject small plastic parts from an injection mold cavity, utilizing the short 20mm stroke for rapid, high-frequency cycling.
Acts as a rugged stop gate on a packaging conveyor, using the CM round-end cover to pivot slightly and absorb the kinetic impact of passing cardboard cartons.
Deploys a 16mm hard-chrome plated rod to index and locate wooden pallets on an assembly line, relying on the G1/4 port for rapid actuation despite the compact body.
To replace the MAL40X20SCM, order the MBL40X20SCM. Verify your setup requires the 40mm bore delivering 628N of thrust at 0.5MPa. If your application needs less force, step down to the 32mm bore (402N push @0.5MPa); if you need more power, 40mm is the largest available mini round size in this series. Confirm your pneumatic plumbing matches the G1/4 port and that your mechanical linkage accommodates the CM round-end back cover. Because this model includes the -S magnet, you must update your sensing architecture: the older CS1-M/DS1-M switches will not fit the new body, so select CMSG, DMSG, or EMSG sensors for the MBL. If your process requires end-of-stroke deceleration rather than a hard stop, step up to the MBLC variant which offers an adjustable air cushion absent on the MAL. Finally, because the fixed rubber bumper is not a locking device, add an external rod lock or pilot-operated check valve if you need to hold a load safely during a compressed air failure.
Upgrade checklist
Yes, the MAL40X20SCM is discontinued. The exact drop-in replacement is the MBL40X20SCM. It offers the same 40mm bore, 20mm stroke, 628N push force, G1/4 port, and CM round-end mounting. You must update your sensors, as the old CS1-M/DS1-M switches are replaced by CMSG/DMSG/EMSG models on the MBL.
At 0.5MPa, the push force is 628N and the pull force is 528N. At 0.7MPa, the push force is 880N. The maximum theoretical force is 128kgf at 1.0MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption; it does not have an adjustable cushion. If adjustable cushioning is required, use the MBLC variant.
