This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X270SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X270SCA 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 MAL40X270SCA (Discontinued) → MBL40X270SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 270mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X270SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X270SCA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 270mm stroke. It delivers a push force of 628N at 0.5MPa (880N at 0.7MPa) and uses a G1/4 port. The exact drop-in replacement is the MBL40X270SCA, matching the bore, stroke, force, port, and CA pivot mounting exactly.
This legacy SKU includes a built-in magnet (-S) for position detection with older CS1-M or DS1-M switches. The original MAL body used threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. The piston relies on a heterogeneous two-way seal that retains grease, while the carbon-steel rod has 20um hard chrome plating.

The MBL40X270SCA 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 beating mechanism on compact textile looms, using the 628N push force at 0.5MPa to pack weft threads tightly into place during high-speed weaving.
Actuates a pivoting diverter arm on a 40mm wide conveyor belt, relying on the CA clevis mount to swing packages smoothly into secondary packing lanes.
Pushes corrugated cardboard cases onto a lower pallet tier, utilizing the 270mm stroke to clear the stacking zone before retraction.
To replace the MAL40X270SCA, order the MBL40X270SCA. Verify your setup needs the CA pivot back cover, which swings on a pin to accommodate arcing loads. Because this is a -S magnet model, note that your legacy CS1-M/DS1-M sensors must be upgraded to CMSG/DMSG/EMSG switches on the new cylinder. The standard PT port thread is retained. If you need to step down, the 32mm bore neighbor provides 402N push at 0.5MPa; stepping up is not possible as 40mm is the largest MAL mini round size. At 270mm stroke, the 16mm rod has low side-load tolerance, so an external guide is recommended. The fixed rubber bumper softens end-of-stroke impact but does not lock the load—if air is lost, the rod drifts. For adjustable cushioning, step up to the MBLC line.
Upgrade checklist
Yes, the MAL40X270SCA is discontinued. The exact drop-in replacement is the MBL40X270SCA, which matches the 40mm bore, 270mm stroke, G1/4 port, CA pivot mount, and 880N push force at 0.7MPa. You simply order the MBL equivalent.
The 40mm bore provides a push force of 628N and a pull force of 528N at 0.5MPa. At 0.7MPa, the push force is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. It uses a G1/4 port and a 16mm carbon-steel rod with an M12x1.25 thread.
