This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X70SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X70SCM 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 MAL40X70SCM (Discontinued) → MBL40X70SCM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 70mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X70SCM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X70SCM is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the legacy range, it delivers a robust 628 N push and 528 N pull at 0.5 MPa, utilizing a G1/4 port and a 16 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced this unit with the MBL40X70SCM, a drop-in alternative that preserves the exact 40 mm bore, 70 mm stroke, output force, and CM round-end back cover. The original MAL features a heterogeneous two-way seal that retains grease alongside a self-lubricating front-cover bearing guide.
Transitioning to the MBL40X70SCM brings structural updates while maintaining operational parity. The legacy MAL uses threaded front and back covers, whereas the current MBL uses a riveted rolling-packed body. This specific SKU includes the -S magnet; the older MAL works with CS1-M / DS1-M switches, but the MBL replacement requires the current CMSG / DMSG / EMSG sensor family. Both iterations rely on a fixed rubber bumper rather than an adjustable cushion, though buyers needing end-of-stroke damping can upgrade to the MBLC variant on the modern line.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X70SCM 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 capping torque heads on rotary beverage lines where 628 N of thrust securely seats threaded caps without crushing the plastic shell.
Actuates a diverter gate in a metal stamping scrap chute, using the CM round-end pivot to absorb angular rod stress during heavy chip ejection.
Pushes corrugated cartons onto a palletizing layer in tight packaging cells, relying on the 70 mm stroke to clear the conveyor lane quickly.
To replace the MAL40X70SCM, order the MBL40X70SCM to match the 40 mm bore, 70 mm stroke, PT thread, and CM round-end cover. Because this SKU includes the -S magnet, you must update your position sensing to the CMSG / DMSG / EMSG switch family, as the older CS1-M / DS1-M sensors are not compatible with the new body. If your fixture permits a smaller footprint, stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa. As the 40 mm bore is the maximum available in this mini round series, applications requiring more power must migrate to a larger ISO profile cylinder. Note that a plain MAL or MBL does not hold its position when air is lost; the rod drifts, so employ an external rod lock for suspended loads. If your cycle speed generates excessive end-impact, specify the MBLC model for an adjustable air cushion.
Upgrade checklist
Yes, the MAL40X70SCM is discontinued. The exact drop-in replacement is the MBL40X70SCM, which matches the 40 mm bore, 70 mm stroke, G1/4 port, and CM round-end mounting. You must update your sensors if you use the -S magnet, as the MBL requires CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
