This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement MBL40X300SUFA, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MAL40X300SUFA (Discontinued) -> MBL40X300SUFA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the MBL40X300SUFA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300SUFA is a discontinued double-acting aluminum mini round cylinder delivering 628 N of push force at 0.5 MPa. It features a 40 mm bore, a 300 mm stroke, a G1/4 port, and an M12x1.25 rod-end thread. The direct replacement is the MBL40X300SUFA, which matches the original bore, stroke, output force, and mounting hardware. The legacy MAL utilized threaded front and back covers, whereas the modern MBL body uses a riveted rolling-packed construction for equally robust performance.
This specific SKU includes a magnet for position sensing, meaning the original MAL worked with older CS1-M or DS1-M switches. When upgrading to the MBL equivalent, you must update to the current CMSG, DMSG, or EMSG sensor family. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has a 20 um hard-chrome plating to resist wear. A self-lubricating bearing guide in the front cover further extends operational life.

Provides 628 N of push at 0.5 MPa to reliably divert heavy pallets along a 300 mm stroke in packaging conveyor lines.
Secures heavy cast iron blocks during machining, utilizing the rigid U flat-end back cover to withstand vibration while clamping.
Pushes finished goods from roller beds into corrugating machinery, where the FA flange ensures stable mounting under fast 30-800 mm/s cycling.
To replace the discontinued MAL40X300SUFA, order the MBL40X300SUFA. Confirm the 40 mm bore, 300 mm stroke, G1/4 port, and PT thread form are correct for your fittings. This SKU has a U flat-end back cover for rigid mounting and an FA flange accessory. Because it includes the -S magnet, plan to swap your legacy CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches on the new MBL. If your application requires adjustable end-of-stroke cushioning, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, you can step down to the 32 mm bore if your application requires less force, which provides 402 N of push at 0.5 MPa. If you need more power, there is no larger bore in this mini round family, so you would need to transition to an ISO 15552 profile cylinder. With a 300 mm stroke, the 16 mm rod is susceptible to bending under lateral stress; use the FA flange to maintain strict alignment or add an external guide rail to absorb side loads. Note that a plain MAL or MBL does not hold its position if air pressure drops; add a pilot-operated check valve or external rod lock for vertical loads.
Upgrade checklist
Yes, the MAL40X300SUFA is discontinued. The direct replacement is the MBL40X300SUFA. It offers the same 40 mm bore, 300 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and FA flange mounting. You can install it directly into your existing setup.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it works with older CS1-M and DS1-M switches; the MBL replacement requires CMSG, DMSG, or EMSG sensors.
